This program covers an investigation of the effect of various maintenance chemicals and fluids on high velocity oxygen fueled (HVOF) coated landing gear and hydraulic piston rods.  HVOF coatings are being used in aerospace industry and in the military to replace chrome-plated parts.  New environmental and health regulations will be severely curtailing exposure levels to the hexavalent chrome present during plating operations.  HVOF plated components are currently being sprayed at Hill AFB and Navy Depots.  A new HVOF system for gas turbine engine parts will be operational next year at Oklahoma City ALC.

This program will screen a number of fluids, such as deicers, hydraulic oil, biocides, cleaners, and fuels to check for potential problems with corrosion of tungsten-carbide-cobalt coat HVOF coated landing gear.  A limited series of tests on HVOF coated hydraulic actuator rods will look at the wear characteristics of the seals during exposure to some of the fluids.  The testing will be conducted at the AFRL on base and at UDRI on-campus.
