Abstract'IBC Materials&Technologies'is proposing to use Plasma Electrolytic Oxidation (PEO) technology to apply a hard, ductile, 100-150 micrometer (.004 - .006 in) thick coating on the bearing housing wall, to be used as anti-fretting, anti-wear, anti-corrosion protection in contact with the bearing steel surface. PEO performance is superior to conventional hard anodizing or plasma spray, is applied at temperatures under 100 degC (212 degF), using environmentally acceptable electrolytes. The microhardness is in the range of 1,800 - 2, 500 HV (microhardness Vickers)and lubricated friction is very low. The porous surface can be easily impregnated with the gear box lubricant
