Tour Black (QPQ)

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.

Common applications of the process are for piston rods of shock absorbers, cylinders and rods for hydraulic systems, pumps, axles, spindles, valves, and now even Golf Clubs.
