** Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is a diffusion process that provides distortion-free dimensional stability while hardening the surface of the part (up to three times the strength of carbon steel) thereby producing superior wear resistance, improved fatigue strength, and surface lubricity. Unlike a plating or a coating, salt bath nitriding adds virtually no dimensions to the part and there is nothing to chip or flake off.
