Phosphate Conversion
Phosphate conversion is the treatment of metals with acidic phosphate solutions.
This process converts the metal surface into a phosphate coat. The phosphating process produces a nonmetallic, oil-absorptive coating on iron and steel surfaces.
Benefits & Properties
- Permits rapid break-in of moving parts without scuffing or welding by preventing metal to metal contact between the bearing surfaces.
- Increases lubrication of treated surfaces due to the oil-absorptive coating.
- Removes light metal scratches remaining from machining operations.
- Retards corrosion.
- Promote the adhesion of paints
We offer 2 types of phosphate coatings
- Zinc phosphate (3 to 5 microns thick, light gray in colour)
- Manganese phosphate (4 to 10 microns thick, dark gray in colour)
