What is the Advantage of Phosphating?

Phosphating is the chemical procedure designed for the steel's surface. In the whole procedure, you rarely get the soluble metal phosphate layers formed on its base. The layers which are created through this are porous and absorbent. It can be converted into the conversion layer for the subsequent powder coating. The Phosphating is also known as temporary corrosion protection if subsequently treated with water, oil & passivation! Let's check what the areas of application are.

 

What are the Phosphate coatings?

Phosphating is the process of transforming a steel surface to iron Phosphate. This method is mostly used for the pretreatment method in conjunction with another corrosion method. The Phosphating layer includes materials like zinc, iron, manganese crystals and more! 

The Phosphate coatings are mostly applied for low alloy steel, carbon steel & cast iron. This solution is mostly applied by spraying or immersing it into the substance. When the steel & iron parts are placed in the Phosphoric acid, it causes a metal reaction that depletes the Hydronium. The Phosphate coating has 2 major functions: paint and powder coatings. The Phosphating procedure contains cleaning the surface, rinsing, surface activation, Phosphating, Rinsing, Neutralizing rinse and Drying.

The Phosphate coating offers improved paint & powder coating adhesion. The phosphating procedure also acts as the corrosion barrier that works as the organic coating. The Phosphating is used as the stand-alone coating for the other procedures. The most basic Phosphating procedures are zinc phosphate, iron phosphate, and manganese phosphate. The phosphating process improves the Phosphate process for balancing the temperature requirements. Let's take a look at some major benefits of Phosphating are:

 

• The corrosion protection is in conjunction with the organic coatings that are polymer films and the paints.
• It protects the corrosion with the waxes and oils protection with zero subsequent treatment.
• These Phosphating procedures are beneficial for improving the anti-friction properties. These are useful for the properties such as wear resistance, anti-galling, friction coefficient and a break-in.
• It offers a strong adhesion bonding for the subsequent painting & other organic coating procedures.
• The cold-forming processes facilitate these for wire drawing & tube drawing, or deep drawing.
• It protects the steel from corrosion and is good for colour coating.
• It improves the electrical insulation & sliding properties.

Overall the Phosphating procedures are beneficial for transmission applications, especially gears. The Phosphated surface offers a vast number of benefits for gears. This Phosphate surface treatment is used to transform the small surface depth for depositing material into this. To get more information, visit A-GAS Electronic Materials.
