摘要：PROBLEM TO BE SOLVED: To provide a copper alloy having wear resistance and excellent in slidability by mixing copper alloy powder with a specified amt. of ceramic powder of specified particle size previously coated with copper or the component the same as those in the copper alloy or the same alloy series and executing sintering. SOLUTION: Into copper alloy powder, ceramic particles previously coated with the components the same as those in the copper or the same alloy series or copper only by a sputtering method are dispersed. As for the ceramic particles, the particle size is regulated to <=10μm. The coating layer of the components the same as those in the copper alloy or copper is applied so as to regulate the thickness to 0.1 to 3μm. The dispersing ratio of the ceramic powder to the copper alloy powder is regulated to 5 to 30 vol.%. As the ceramic powder, diamond, boron nitride, sapphire, graphite, molybdenum disulfide, tungsten disulfide, silicon carbide and boron carbide are used.
