An Alternative to Hard Chrome Plating

A process of Nickel-Tungsten-Silicon Carbide plating was developed as an alternative to hard chrome plating.

This new plating process has superior abrasion resistance and several advantages over hard chrome plating.

One meritorious effect of this process is that the plating bath contains no hazardous ingredients such as hexavalent chromium contained in a chrome plating bath.

The plating solution is neutral in pH and causes no pollution control or labor safety problems.

Therefore this process will be an environmentally suitable candidate for a replacement process to hard chrome plating in the aerospace industry.

This paper describes various features of the process.
