ABSTRACT:
In a part for a rotary machine, a ceramic hard film is formed on a surface of a base material, the density of droplets which exist in a surface of the ceramic hard film is set to be within 1000 pieces/mm2, and the density of droplets whose mean particle diameter is 1 μm or less is set to be within 550 pieces/mm2. A method for manufacturing the part of a rotary machine is a method for forming the ceramic hard film by at least an ion plating method or a sputtering method.
