Abstract:
1. A slide part configured to be used in an environment where there is a lubricant containing molybdenum dialkyldithiocarbamate and/or molybdenum dithiophosphate, the slide part comprising a hard protective layer formed on an outermost surface of a substrate of the slide part, and a plurality of interlayers sandwiched between the hard protective layer and the substrate, wherein: the hard protective layer includes 59 at. % or more of carbon, and includes nitrogen, and a metal element; the hard protective layer is composed of a complex of an amorphous carbon body containing nitrogen and a compound crystal of the metal element; the compound crystal is composed of at least one of a metal carbide, a metal nitride, and a metal carbonitride; a surface hardness of the hard protective layer is 1800 or larger in Vickers hardness, the plurality of interlayers are composed of a first interlayer formed of the metal element immediately on the substrate, a second interlayer formed of the metal element and the metal carbide immediately on the first interlayer, and a third interlayer formed of the metal carbide and the amorphous carbon body immediately on the second interlayer, and a composition profile of at least the second interlayer continuously varies from an interface with the first interlayer to an interface with the third interlayer in a thickness direction.
