Tungsten Carbide Coating

Protective coatings are provided in the form of hard chrome plating or tungsten carbide (WC) coating by HVOF process. These coatings are provided by sophisticated machinery which is supported by skilled technicians for finish polishing providing excellent surface finishes and dimensional accuracy. These skilled technicians also carry out the finish polishing of hard chrome plated rotors. In certain cases, chrome plating is replaced by tungsten carbide when the pitting depth on the rotor is found to be higher than that recommended for hard chrome plating.

Micro porosities formed during coating are filled by the densification process. Rainbow provides densification using chemical sealants and baking which increases the life of the coating.
