Zusammenfassung:	A sliding part (10) with a wear resistant coating includes a sliding part (12), and a wear resistant coating (14) provided on a sliding surface (12a) of the sliding part (12), and made of a cobalt alloy containing chromium and silicon. In the wear resistant coating, oxide particles (16) are dispersed which include an oxide containing chromium and silicon, and have a particle size of 100 µm or less when a cross section of the wear resistant coating (14) is observed using an optical microscope with a magnification of 100 times.
