Phosphating: Unparalleled Surface Protection

Introduction

Phosphate Wires

Surface treatment has been an integral part of metal finishing for centuries, and one method that has stood the test of time is phosphating. This chemical conversion process, dating back to the 19th century, has evolved and found diverse applications in modern industries. In this blog post, we explore the historical roots, general aspects, benefits, and applications of three common types of phosphating: zinc, manganese, and iron phosphating.

Historical Roots of Phosphating

The earliest work on phosphating can be traced back to the 19th century. Initially, it was used as a method to improve the corrosion resistance of iron surfaces. Over the years, researchers refined the process, and its applications expanded to various metals, including steel, aluminium, and zinc. During World War II, the technique found its initial widespread application in the production of firearms for the United States military.

General Aspects of Phosphating

Phosphating is a chemical conversion process that involves the formation of a phosphate coating on metal surfaces. It is typically performed through immersion or spraying in a solution containing phosphoric acid or other phosphates. The reaction between the metal surface and the phosphate solution results in the formation of metal phosphate compounds, creating a protective layer.

Three Common Types of Phosphating

Zinc Phosphating: This type of phosphating is widely used due to its superior corrosion resistance and paint adhesion properties. It is commonly applied to steel and iron surfaces, protecting them from rusting and ensuring better paint adhesion for subsequent coatings.

Manganese Phosphating: Manganese phosphating provides excellent wear resistance, making it ideal for applications in which metal surfaces are subject to friction, such as gears and automotive components. Additionally, it offers moderate corrosion protection.

Iron Phosphating: Iron phosphating is commonly used as a pretreatment method for steel surfaces before painting. It enhances paint adhesion and provides moderate corrosion protection.

Benefits of Phosphating

  • Corrosion Resistance: Phosphating forms a protective layer on metal surfaces, shielding them from corrosive environments, such as saline or coastal regions, and increasing their lifespan.
  • Paint Adhesion: Phosphating provides an ideal surface for the adhesion of paints, primers, and coatings, ensuring long-lasting and durable finishes.
  • Lubricity and Wear Resistance: Certain types of phosphating, like manganese phosphating, offer lubricity and wear resistance, reducing friction and extending the life of components subject to mechanical stress.

Applications in Various Industries

From automotive to aerospace, phosphating finds applications in diverse industries, ensuring that metal components stand strong against the challenges of time and the elements. The versatility of phosphating has led to its widespread adoption across numerous industries, including:

  • Automotive: Used for automotive components like fasteners, chassis, and engine parts to improve corrosion resistance and paint adhesion.
  • Aerospace: Phosphating protects aircraft components from the harsh conditions of the sky, enhancing their longevity and reliability.
  • Machinery: Metal gears, shafts, and hydraulic components benefit from phosphating’s wear resistance and anti-corrosion properties.
  • Construction: Steel used in construction applications benefits from the enhanced corrosion protection provided by phosphating.

Phosphating, with its historical roots and continued relevance in modern industries, remains a vital surface treatment process. Whether it’s zinc, manganese, or iron phosphating, this time-tested technique offers numerous benefits, including corrosion resistance, paint adhesion, and improved wear resistance.

Advantages of zinc aluminum flake coating.

Different advantages of zinc aluminum flake coating are as follows :

  1. No Hydrogen embrittlement – The treatment process of zinc aluminum flake coating do not involve treatment with acid for removal of corrosion products like mill scales, rust. Mechanical cleaning (shot blasting, grit blasting) followed by coating avoids the risk of hydrogen embrittlement.
  2. Overall coverage – The coating process is non electrolytic. Articles are coated by dip mode of application or spray mode of application depending on size, weight of article. The articles are coated ensuring complete coverage.
  3. Corrosion resistance – The corrosion resistance is higher due to overall coverage and also due to sacrificial protection of zinc /aluminum flakes. The film structure is like brisk wall minimizing penetration moisture. The film also has self healing property.
  4. Thermal stability – Cured film of zinc aluminum flakes do not changes its properties even at higher temperatures. There is no degradation in corrosion resistance property.
  5. Excellent adhesion and recoat ability – Zinc aluminum flakes coating film adheres firmly to metal surface. It has also excellent recoat ability. Top coat with different lubrication properties can be applied on zinc aluminum flake coating to further enhance different properties.
  6. Free from pollution – The water-based zinc aluminum flake coating process do not involve generation of waste water. The coating is free from water and air pollution.

Generally zinc aluminum flake coating process involves cleaning to remove oil, shot blasting to remove rust/mill scales, coating and curing. Desired properties are achieved essentially with two coats. The properties are further enhanced by application of suitable top coat.

Zinc Aluminum Flake Coatings

Use of ferrous and non- ferrous material is unavoidable in the industry due to its availability, strength, durability, work-ability and ability to recycle. Automobiles, bridges, house- hold appliances, power generation equipment’s, railways, engines etc. are manufactured using ferrous and non -ferrous materials by adjusting metal properties in terms of hardness, flexibility, resistance to corrosion, weight to strength ratio etc.

Loss of metal due to various types of corrosion processes is a perennial problem in the industry. Thousands of dollars are wasted due to loss of metal (corrosion) and also thousands of dollars are invested in protecting the metal from corrosion. This in turn increases the life span of manufactured items, avoids the probable risk of accident.

Use of different types of fasteners, nuts, bolts, clips are necessary to manufacture different articles. The adequate strength required for the articles is provided by different sizes of fasteners, nuts and bolts.  Fasteners are subjected to failure due to atmospheric corrosion, hydrogen embrittlement, temperature variations and bi- metallic corrosion.

Different types of phosphating systems and also painting systems with different types of resins, film thickness varying from few microns to few millimeters are used to protect the main structure. However higher film thickness of any coating is a limiting factor for fasteners.

 Different types phosphating, blackodizing, zinc plating followed by passivation layers are used to improve the corrosion protection of fasteners. However, zinc plating has limitations in terms of corrosion protection and possibility of hydrogen embrittlement. Adverse effect on environment due to use of hazardous chemicals also needs to be considered while using such coatings.

Zinc aluminum flake coating is developed with the extensive research to provide protection against all types of corrosion for fasteners, brake disc etc with a very thin film of 6~10 microns. Zinc aluminum flakes with water or solvent based, binders free from hexavalent chromium (environmentally friendly) and adequate additives to improve different properties are widely used in the industry. Even at low film thickness zinc aluminum flake coating provides excellent protection against corrosion considering different environmental cycles. Zinc aluminum flake coating also helps in preventing bi metallic corrosion.

Electroless Nickel – All You Need to Know

Electroless Nickel Plating (ENP) is the deposit of a nickel-phosphorous alloy coating by autocatalytic chemical reduction – without the electric current.

The majority of ENP for engineering purposes is a nickel-phosphorus alloy deposit containing 2 to 13% phosphorus by weight.

Higher the phosphorus content the greater is the corrosion resistance, however, on increasing the phosphorus content, the hardness of the coating decreases.

  • Highphos ENP: P-content 10 – 13%, high corrosion resistance (>25 µm, >1000 hrs NSS), hardness as plated 450 – 550 HV
  • Midphos ENP: P-content 6 – 9% moderate corrosion resistance (>25 µm, >96 hrs NSS), hardness as plated 550 – 650 HV
  • Lowphos ENP: P-content 2 – 5% low corrosion resistance (>25 µm, >24 hrs NSS), hardness as plated 700 – 800 HV

ENP is deposited by reducing Ni2+ cation to metallic nickel with a chemical reducing agent such as sodium hypophosphite or borohydride or DMAB. In the course of chemical reduction, some phosphorous generated gets deposited along with reduced Ni-metal to form a Ni-P Alloy Thickness of 15 – 75 µm, this is very common for most of the application, but for some specific applications high phosphorus ENP can edge above 75 µm also, especially, for very high corrosion and wear resistance requirements.

The advantages of electroless nickel plating

ENP offers excellent corrosion resistance against most of the common corrodents such as saltwater, carbon dioxide, oxygen, and hydrogen sulphide, etc.

High phosphorus deposit of ENP (10-13% phosphorous) is amorphous in nature, which means that there are no grain or phase boundaries to create active sites for the initiation corrosion.

The uniformity of ENP versus electrolytic deposits is very advantageous for plating irregular and complicated shapes of substrates. ENP deposits a uniformly thick coating across the whole substrate; even in slots, holes, and inside walls of the tubing.

Without heat treatment, corrosion-resistant of high phosphorus ENP is very high and also has good hardness and wear resistance properties. Hardness can be increased more than doubled by heat treatment with a bit of compromise in corrosion protection.

ENP offers a cost-effective solution for applications subject to conditions where wear and corrosion are factors; extending service life and providing a lower-cost alternative to corrosion-resistant alloys, particularly where carbon steel suffers localised corrosion; flange attack or weld corrosion.

What are the properties of the deposit and factors affecting them?

ENP provides excellent corrosion protection and uniformity in thickness of deposit along with good hardness. The phosphorus content of the deposit can be chosen as per the requirement of the application.

At Grauer & Weil our technical team understands each customers’ application and its requirement before recommending the optimum phosphorus level – the higher the phosphorus content the greater the corrosion resistance but lower the hardness.

Hardness of ENP can be increased by heat treatment but this produces a micro-crack in the deposit which reduces the corrosion resistance of the coating.

Uniform thickness distribution and alloy composition on complex shapes are the biggest advantages of Electroless plating over electroplating.

How does heat treatment affect ENP?

ENP is at its most corrosion-resistant in its amorphous phase. Heat treatment causes particles of nickel phosphide (Ni-Ni3P) to precipitate, destroying the amorphous character of the deposit. With highphos ENP deposits, this occurs at temperatures between 300 and 395 °C.

How well does ENP adhere to substrates?

Adhesion is dependent on effective cleaning of the substrate. With good surface preparation adhesion to carbon steel is between 200-420 MPa. With stainless steels, the bond strength is usually between 120-160 MPa.

What factors affect plating quality?

There are several factors affecting plating quality and they should be effectively managed by your surface finishing partner.

– Surface preparation: Rough, badly machined surfaces with uneven metal surfaces, burrs, or cold shuts cannot be effectively plated.

– Cleaning: Surfaces must be free from oils, dirt, and soaps formed by saponification of oils by alkaline cleaners.

– Control of the baths and operating parameters: Temperature, pH, nickel ion concentration, and hypophosphite concentration all need to be carefully managed to ensure high quality and consistent plating finish.

What are the fabrication/finishing requirements before plating?

Weld spatter should be removed, sharp edges radiuses and weld roots ground smooth. When refurbishing/remanufacturing components it is important that corroded areas are ground to a flat surface.

Some other key considerations

When looking to choose a suitable partner for your electroless nickel plating requirements it is important to check for several factors:

– Will surface inspection be completed prior to plating?

– Are the chemicals supplied by a certified ENP product supplier?

– Are ENP solutions made up with demineralized (DM) water?

– Is continuous filtration of the bath to 3 microns done along with air agitation?

– Is bath chemistry (Ni2+, hypo, buffer, etc.) monitored regularly by chemical analysis?

– How regularly are plating Tanks cleaned?

– Is the inspection of the plating line carried out to sufficient levels?

Heart of plating.

At Growel, automation is at the heart of all our plating plants. Keeping this in mind our team, in technical collaboration with Utikal Automation Germany, is working with GalvCon V4.0, a PC-based software exclusively developed for atomization of surface finishing processes. The software is developed to be rich in features and provide ease in operation even when there is a need for replacement and modification.

This automation package is developed in such a way that the “intelligent part” of the software is written on the PC whereas the “driving program”, which rarely requires any changes, is written to the PLC. A highly reliable and powerful TCP/IP connection is established with Siemens S7 controller which requires no special drivers or third-party software for communication.

Initiating the plant operation is as easy as entering the article number and quantity to be loaded, the software initiates the cycle with minimum manual intervention.

Each article is pre-assigned with a unique process flow program (sequence of movement with time) and a power program (current density setting). Every article is capable of having a different process flow and current density program. The system has no limitation on the number of articles and their subsequent programs. The process program is designed to include parameters such as order of the baths, residence times, current setting in electrolytic baths, automatic dosing, temperature control in heating/cooling baths, and control of accessories along with visualization. The most powerful feature of this software is the capability of having flexible cycles. With this feature different articles having different process flow programs (different articles need to be processed in different baths with different timings) can be loaded onto the plant as per the user’s output demand.

The software is designed in such a way that the operator is allowed to load articles randomly as required and the intelligence of the software will decide the right sequence of the flight bar movement in the plant. The loaded flight bars may be temporarily stored at the buffer station or maybe directly taken for processing. The software will calculate the most efficient sequence of flight bar entry into the plant ensuring the most optimal usage of the baths and the transport wagons.

GalvCon V4.0 enjoys the following features and advantages:

  • Multi-level Password protection for avoiding operator level errors.
  • Multiple computers can be connected in the network for visualization but only one PC has the master process control.
  • Remote system connectivity is possible for process and status visualization through the Internet.
  • A special Loading terminal can be provided, to select the article while loading with visual identification.
  • Vast flexibility for process control.
  • Software can be quickly tailored to suit user needs.
  • Process and current programs can easily adapt to change in plant structure.
  • High stability and reliability.
