摘要： In the field of biocompatible Co—Cr—Mo alloys for use in artificial joints or the like, the formation of wear debris in a living body is a matter of concern. The purpose of the invention is to provide a technique for improving the wear resistance of a Co—Cr—Mo alloy for use in an artificial joint to thereby prevent the formation of wear debris in a living body. The improvement in wear resistance of a Co—Cr—Mo alloy for use in an artificial joint can be achieved by finely dividing the crystal particles of the alloy, by preparing an alloy composition having a higher Mo content than any known standard Co—Cr—Mo alloy (e.g., Co-29Cr-6Mo alloy), by increasing the proportion of the σ phase that is dispersedly precipitated, by sintering an alloy powder produced by gas atomization technique to form pores on the surface of the alloy material, or the like. The Co—Cr—Mo alloy having high wear resistance is applicable to medical devices including artificial hip joints, artificial knee joints and the like which have less biotoxicity, namely which are safer and have a longer useful life.
