A plain bearing with composite interplayer

摘要

This invention relates to a method of applying a coating layer 90 to a bearing substrate 93 which contains a matrix of particles 91 within the coating. The particules 91 are contained within an electrolytic solution along with the surface to be coated 93. Electoplating is used to deposit the metal ions 92 as well as the hard or soft tribologically useful particulates 91 onto the surface 93. Ultrasonic or megasonic agitation is used to scatter and disperse the particles 91 within the electrolytic solution to ensure a uniform concentration of particles 91 near the surface 93 of the part.
