A coating consists essentially of one or more selected from the group of nitrides of one or more first metals of titanium, zirconium and hafnium beyond 0 at % but less than 100 at % and a balance of silicon, and nitrides of one or more second metals of vanadium, niobium and tantalum.

Compressor vane or blade for engine

When a compressor vane or blade for an engine is used in an environment containing abundant foreign substances, deposits originated from the foreign substances are likely to deposit on surfaces of the vane or blade. The compressor vane or blade according to the present disclosure has a base body of the compressor vane or blade; and a coating covering the base body, which consists essentially of one or more selected from the group of molybdenum disulfide and tungsten disulfide.
