Thermal fatigue of WC coatings deposited with HVOF

More Information
  • Received Date: July 04, 2005
  • The thermal shock resistance of the WC coating deposited with HVOF was studied. The results indicated that HVOF coatings after 15 times thermal shock are all perfect without any defects as crack, spalling. In contrast with, the coatings deposited with plasma have cracked and spalled completely after 3 times thermal shock. HVOF WC coatings resistance ability to thermal shock is very excellent.
