Title: Sliding member with composite plating coat
Inventor: KAWACHI TOSHIAKI
IPC: C22C11/06
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce the wear amount of a sliding member itself as well as the wear amount of a mating material and provide an excellent fatigue resistance in the sliding member having a composite plating coat formed by diffusing inorganic particles into a lead alloy including Cu. SOLUTION: The ratio of the inorganic particles to all occupied in the composite plating coat 4 is 0.3 to 25 vol.%, the ratio of Cu to all occupied in the composite plating coat 4 is 0.1 to 10 wt.%, and the inorganic particles and Cu are not contained in an outermost surface layer 4b having a thickness of 10 to 40% of the thickness of the composite plating coat 4. Also, Cu is not contained in the outermost surface layer 4b of the lead alloy composite plating coat 4. Even if Cu is present therein, its amount is very small and, therefore, the initial running-in of the composite plating coat 4 at the start of the operation can be improved, and an abrupt seizure problem can be eliminated.  When wear moves to a normal wear after sufficient running-in, the layer containing the inorganic particles and Cu under the outermost surface layer 4b is exposed and, therefore, the wear of the sliding member can be prevented and the sliding member becomes hard to cause a fatigue.
