CORROSION RESISTANT COATING

THIN DENSE CHROMIUM PLATING (TDC)

Thin Dense Chromium plating can be applied to both the combined roller bearings & the steel rails. However, it is the bearings that are more frequently coated as, unlike the steel, they can not be painted or galvanised.

What is it?

A thin deposit of Chromium from 1 to 15 microns thick is deposited on all external surfaces.

These meet ASTM adhesion and bend tests. Surface hardness shows no brittleness or micro-cracks when viewed at magnification x 500.

Samples shall pass standard ASTM B-117 & B-287 Salt spray tests. A detailed brochure on this specific method is available on request.
