砲能低下または故障に至るという不具合が生じ易い。For example, in a rotary compressor, a cylinder chamber is defined by a vane whose tip end is pressed against an eccentric roller. When this type of vane is used for a long period of time, the tip or the mating member such as the biased roller will wear out.
Problems that can lead to decreased gun performance or malfunction are likely to occur.

フィング摩耗が発生する。This is because the material of the vane is usually made of steel or cast iron, and the material of the vane is usually made of synthetic resin material, and although it is a slippery material that cannot be expected to form a lubricating oil film, it has a low PV value (surface pressure). This causes adhesive wear and scuffing wear with mating parts.

度摩耗が少い結果を得た。For example, in a machine in which the row 27 is made of cast iron and the base material of the page 78 is made of chromium-based steel, according to experimental data that detected the wear state of each after 2000 hours of operation, vanes 8 and rollers whose pressure welding parts 10 are ceramic coated. No wear was observed at all in the mutually sliding contact parts of No. 7, and the wear was about 10 to 100 times less than the specification without ceramic coating.
