'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… More

The development of the F-35 LiftFan has revealed the possibility of fretting between the fan input shaft bearing OD surface and the aluminum gearbox housing. A steel insert is currently used to provide protection against fretting of the gearbox housing. In order to provide an effective solution… More

Pyrowearr 675 is noted as a high performance bearing material used in turbine engine and other higher temperature applications. The mechanical properties and stability necessary for these applications is achieved via carburizing by design. The carbides that form to provide the hot hardness and… More
