Quench-Polish-Quench (QPQSM)
HP&C is the only company in Houston authorized to provide the remarkable QPQSM process.
QPQSM or Quench-Polish-Quench, is particularly important to companies such
as oil field service firms whose parts operate for extended periods in highly corrosive environments and
are subject to high levels of friction. QPQSM is a deposition 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. The QPQSM
excellent corrosion protection of cast iron and steel components, and is an effective and environmentally
acceptable alternative to chrome and cadmium coatings.
Additionally, the QPQ process produces a cosmetically appealing black finish.
