MACHINE COMPONENT AND PRODUCTION METHOD FOR SAME

摘要

One example of this machine component is a sprocket that is provided with a base that comprises a first metal and with a build-up layer (90) that is disposed in contact with the base so as to cover at least one section of the surface of the base. The build-up layer (90) includes a parent phase (95) that comprises a second metal, and includes hard particles (91) that are dispersed in the parent phase (95). The surface (90A) of the parent phase (90) is a forged surface. The hard particles (91) that are positioned inside a build-up layer surface region (90B) that is within the average particle size of the hard particles (91) from the surface (90A) of the build-up layer (90) are embedded in the build-up layer (90) side by side.
