Phosphating

Phosphating is a chemical process for treating the surface of steel, where barely soluble metal-phosphate layers are formed on the base material. The layers created are porous, absorbent and suitable as a conversion layer for subsequent powder coating without further treatment. They are also ideal as temporary corrosion protection if subsequently treated with oil, water or passivation.

 

Main areas of application/advantages

  • Temporary corrosion protection for steel, which is to be stored for a limited period before further treatment
  • Good promotion of adhesion for subsequent colour coating
  • Improves the sliding properties with cold forming steel
  • Electrical insulation
