Abstract
A sprocket wheel, which is an example of the machine component, includes a base made of a first metal, and an overlay disposed in contact with the base to cover at least a part of a surface of the base. The overlay includes a matrix made of a second metal, and hard particles dispersed in the matrix. The surface of the overlay is a forged surface. The hard particles located in an overlay surface region within an average particle diameter of the hard particles from the surface of the overlay are arranged side by side while being embedded in the overlay.
