Zinc Phosphate Coating Services

Zinc phosphating, also known as zinc phosphate coating, is a type of conversion coating used to protect steel surfaces. Here's a detailed profile:
Process

• Cleaning: The steel surface is thoroughly cleaned to remove any contaminants.
• Rinsing: The cleaned surface is rinsed to remove any cleaning agents.
• Phosphating Bath: The steel is immersed in a zinc phosphate solution, typically at a temperature of around 50-75°C. This causes a chemical reaction that forms a layer of zinc phosphate on the surface.
• Rinsing: The phosphated surface is rinsed again to remove any residual chemicals.
• Sealing: The surface is often sealed with oil or another protective coating to enhance corrosion resistance.

Benefits

• Corrosion Resistance: Provides excellent protection against rust and corrosion.
• Adhesion: Enhances the adhesion of subsequent coatings or paints.
• Wear Resistance: Improves the wear resistance of the treated surface.

Applications

• Automotive Industry: Used for engine components, gears, and other parts that require high wear resistance.
• Military and Defense: Applied to weapons and ammunition for corrosion protection.
• Machinery: Used in various machinery parts to improve durability and performance
