摘要

#CMT# #/CMT# Bearing component comprises a coating for electrical insulation, comprising a silane and/or a siloxane compound, a metal alcoholate, polyether ether ketone (PEEK) and/or polytetrafluoroethylene (PTFE) as dispersion. #CMT# : #/CMT# An independent claim is also included for a coating method for a bearing component, comprising applying the coating on the bearing component, and subsequently sintering by pulsed magnetic induction on the component surface. #CMT#USE : #/CMT# The bearing component is useful in food industries, electronics manufacturing, power transmission and hydraulic and other media-lubricated applications. #CMT#ADVANTAGE : #/CMT# By the bearing component and/or by the coating method, it is possible to combine excellent tribological properties with simultaneous mechanical strength and electrical insulation in a layer. The layer exhibits a thermal stability of 350-380[deg] C. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The silane- and/or siloxane compound is acyloxy silane, alkyl silane, aminosilane, bis-silyl-silane, epoxy silane, fluoro alkyl silane, glycidoxy silane, isocyanate silane, mercapto silane, (meth)acrylate silane, mono-silyl-silane, multi-silyl silane, sulfur containing silane, ureido silane and/or vinyl silane. Preferred Method: The method is performed under protective gas atmosphere or vacuum. The produced coating has a thickness of 1-25 mm (sic), preferably 1-10 mm (sic). The coating is applied on a rolling bearing component made of 16MnCr5, C45, 100Cr6, 31CrMoV9 or 80Cr2 steel. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Composition: The coating further comprises a solvent mixture made of organic solvent, an organic polymer, which is obtained by polymerization of olefinic unsaturated monomers, a surfactant comprising a wetting agents, deaerators and/or defoamers. #CMT#EXAMPLE : #/CMT# No suitable example given.
