Surface technology process: Phosphating

Phosphating, depending on the crystal structure, is very suitable as a primer for subsequent coatings. It improves drawing, sliding properties and also guarantees a temporary corrosion protection, especially in combination with suitable oil.

In the HEICHEGROUP the following phosphates used:
Manganese phosphate , Zinc phosphate & Zinc calcium phosphate

Advantages of manganese phosphating at a glance:

Good temporary corrosion protection, corrosion resistance up to 72 h salt spray test. Fine crystalline layer structure. Reduction of the coefficient of friction. Improvement of the sliding properties / the running-in behavior of gear elements.

We use this process for these materials:
