• Navy CH-46 program providing $800K to Boeing for rig testing of
HVOF-coated aft-vertical shaft and forward carrier shaft
• ESTCP Project Manager to issue short-term contracts to companies
to develop test requirements for insertion into a JTP
OEM Tasks Under Contracts
• Conduct analysis of types of dynamic components onto which
OEM applies hard chrome or thermal spray coatings, including
operating environments, mating surfaces, stresses in service
• Conduct visit to NADEP Cherry Point and/or Corpus Christi
Army Depot to perform analysis of types of dynamic components
being repaired at depots, including above parameters
• Identify materials tests that OEM believes would be required to
qualify HVOF coatings on various components onto which either
OEM or depot currently applies hard chrome
• Identify component tests required to qualify HVOF coatings
• Participate in meetings to develop Joint Test Protocol(s) and assist
in writing of JTP
