What are the anti-corrosion treatment methods for metals?

There are many ways to treat metal surfaces. If the anticorrosion requirements of metal parts are high, special treatment technology is needed. QPQ treatment process is a kind of heat treatment process, which can increase the hardness of the mechanical workpiece to be treated and improve the wear resistance, corrosion resistance and bite resistance.

QPQ treatment is a composite treatment technology, which is based on nitriding and oxidizing salt bath treatment, and realizes the composite treatment of nitriding and oxidizing at the same time. QPQ treatment can greatly improve the wear resistance and corrosion resistance of metal surface, which is 60 times higher than that of conventional hardening treatment.
