Degreasing Coating Raw Parts Cleaning & Phosphating Drying
Degreasing
Pre-treatment operations are used to remove oils and light rust prior to coating.
Coating Raw Parts
The dry bulk zinc aluminium powders are combined with parts and heated at prescribed times and temperature in the retort chamber.
Cleaning & Phosphating
Parts are rinsed to remove coating dust after the heating cycle and passivated with a zinc phosphate solution.
Drying
All parts are dried and packed for shipment.

COATINGS THAT WITHSTAND CHALLENGING CONDITIONS.
 

GREENKOTE® offers coatings for hard surface applications and coatings for high temperature conditions.

HC – Hard coatings group

Our HC series features hard-facing coatings based on chromium and vanadium, carbides and nitrides, in addition to inter-metallic options. Hard coatings work best for steels, stainless steels, cast irons, titanium and nickel alloys. They are adaptable to specific needs at low, medium and high temperatures. In addition, this coating line offers:

  • Wear resistance and low friction
  • Metal-to-metal anti-seizing properties

HT – High temperature coatings group

Our HT-Tri metal coatings are for high temperatures oxidation protection and anti-seizing properties. HT-2A is suited for stainless steels and nickel alloys. HT-2C works best with carbon and low-alloy steels and cast iron. HT-2T is used on titanium alloys.

This coating line offers:

  • High temperature oxidation resistance
  • High temperature anti-seizing
  • High temperature wear resistance
  • Base material cost savings
