ABSTRACT:
The present invention relates to a composite sliding member having a backing metal and a sliding layer consisting of lead-containing copper alloy and being bonded to the backing metal, and to the method of producing the same. The present invention resides in more superior sliding performance exhibited due to uniform and fine distribution of lead particles in the copper alloy matrix. The method of the present invention to produce composite sliding members comprises using the atomized powder in which lead particles are finely and uniformly distributed in the alloy matrix and forming a cladding layer as the sliding layer through a plasma arc welding apparatus.
