    摘要: A composite nickel plated sliding surface is obtained by the formation of a composite nickel plating film on a sliding surface of an automobile part such as an engine cylinder or piston by electroless nickel plating. The plating film contains at least one member of wear resistant particles having an average particle size of 0.1 to 1.0.mu. selected from SiC, TiC, WC, BC.sub.4, TiN, Al.sub.2 O.sub.3 or the like, and also at least one member of lubricating particles having an average particle size of 1 to 10.mu. selected from BN, MoS.sub.2, and Teflon. The nickel plating bath is adjusted to have a phosphorus concentration of 0.5 to 12%. When the matrix of the nickel plating film has a phosphorus concentration of 0.5 to 5%, the film hardness is improved.
