CHROMIUM PLATING

Chromium plating is used for corrosion protection, as a decorative coating and to create a wear-resistant and hard surface.

 

WHICH MATERIALS ARE SUITABLE FOR CHROMIUM PLATING?

Several types of metal are suitable for chromium plating:

Steel Cast iron
Stainless steel

Nitro-carburised steel (<10 μm)

Aluminium

Tenifer-treated steel and sintered materials 

Brass

Copper and copper alloys 

 

PRE-TREATMENT

If you want a shiny surface, the item should be burnished and polished. The surface is typically coated with polished copper and polished nickel previous to chromium plating: The copper levels and smooths out the surface, while the nickel gives it a hard base. The nickel coating can be either shiny or matt.

The chromium and nickel coating functions as a barrier to the surroundings and should be fully sealed. The typical thickness of the layer is 2-12 μm, providing moderate protection. For outdoor use the thickness should be increased or a middle layer of copper should be added.

 

THE PROCESS OF CHROMIUM PLATING

  • The items are degreased and pickled.
  • Chromium plating is deposited electrolytically.
  • The items are dried in a fan-assisted oven.

Lacquering and colour-printing can be done subsequently.
