The vanadium carbide coating technology transforms the working surface of the tools into a super hard protective layer. Multiple heat treatments are not required.
Steps in the vanadium carbide process include cleaning, preheating, coating, cooling or quenching and subsequent tempering as required.
Cleaned parts are preheated and then immersed in an environmentally benign fused salt bath. Parts are soaked until the required coating thickness is achieved, and then removed from the furnace for quenching, slow cooling, and tempering.The thickness is normally about 15 microns.
