Chemical conversion treatments allow the formation of a crystalline phosphate layer, including Mn, FeMn, Zn, ZnFe, and ZnCa types.
Main characteristics:
– Manganese-type phosphating:
– Reduces friction- Improves the adhesion of lubricating films
Zinc-type phosphating:
– Increases corrosion resistance
– Provides an excellent base for organic coatings
Applicable materials:
– Ferrous alloys – Aluminum coatings – Zinc alloys – Cadmium coatings
Typical applications:
– Spur gears – Gleason couplings – Transmission pinions – Camshafts – Rocker arm shafts – Automatic weapon bolts – Firearm components – Tie plate pins – Faucet bodies – All overmolding applications – Automotive fasteners
