Phosphate Coating Services
Phosphate coating is a chemical treatment applied to steel and iron surfaces to improve corrosion resistance, paint adhesion, and wear resistance. Often used as a pretreatment for painting or lubricating, phosphate coatings form a thin, crystalline layer that enhances surface performance in demanding environments.
Types Offered:
- Zinc Phosphate – Ideal for corrosion resistance and as a base for paint or powder coating
- Manganese Phosphate – Provides excellent wear resistance and is often used in engine components or parts requiring oil retention
- Iron Phosphate – A lighter coating used mainly for paint adhesion and moderate corrosion protection
Key Benefits:
- Improves corrosion resistance
- Enhances paint and coating adhesion
- Reduces friction and wear
- Uniform surface finish
- Cost-effective surface treatment for steel components
Typical Applications:
- Automotive parts
- Fasteners and hardware
- Military and aerospace components
- Tooling and mechanical assemblies
At Directional Manufacturing, our phosphate coating process is controlled to meet industry standards such as MIL-DTL-16232, TT-C-490, and ASTM B633 (where applicable), ensuring consistent quality and performance.
