Phosphating

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

Main areas of application/advantages

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