Sliding part with wear resistant coating and method of forming wear resistant coating

A sliding part with a wear resistant coating, comprising:

• a sliding part;
• and
• a wear resistant coating provided on a sliding surface of the sliding part, and made of a cobalt alloy containing chromium and silicon, wherein
• spherical oxide particles are dispersed in the wear resistant coating, the spherical oxide particles being made of an oxide which contains chromium and silicon, and having a particle size of 100 μm or less when a cross section of the wear resistant coating is observed using an optical microscope with a magnification of 100 times,
• when a 300 μm×300 μm area in the cross section of the wear resistant coating is observed using the optical microscope with the magnification of 100 times, 10 or more spherical oxide particles with a particle size of 10 μm or less are present therein, and
• the spherical oxide particles are dispersed in a surface of the wear resistant coating, and in a thickness direction of the wear resistant coating, and
• the wear resistant coating comes into direct contact with a counterpart and slides thereon.
