Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). This process is often used when two or more of the following properties are required in a workpiece: * wear resistance * corrosion resistance * lubricity * fatigue strength
