摘要：【課題】圧接部の高摩擦係数と摺接部の低摩擦係数を両立できる高効率な自動変速機を提供する。【解決手段】本発明の自動変速機は、対向する一対の圧接面を有する圧接部と、対向する一対の摺接面を有する摺接部と、圧接面間および摺接面間に介在する作動潤滑油とを備える。摺接面の少なくとも一方は、Bを含有した非晶質炭素膜(以下「B−DLC膜」という。)により被覆されている。作動潤滑油は、Mo:50ppm以下およびZn:50ppm以下であると共に、B:90〜300ppmを含む。作動潤滑油はMoやZnを含まないため、B−DLC膜で被覆されていない圧接部で高摩擦係数が確保される。一方、Bを従来よりも多く含む作動潤滑油と摺接面を被覆するB−DLC膜とが相乗的に作用することにより、摺接部における摩擦係数を大幅に低減できる。こうして本発明によれば、従来よりも低損失で高効率な自動変速機を提供できる。【選択図】図3

摘要： PROBLEM TO BE SOLVED: To provide an amorphous-carbon coated member exhibiting not only good wear resistance but also low aggressiveness against mating member simultaneously.
SOLUTION: The amorphous-carbon coated member according to the present invention comprises a conductive substrate, and an amorphous carbon film fixed onto a part of a surface of the substrate at least. Moreover, the amorphous carbon film comprises a compositionally gradient film. The compositionally gradient film is composed of carbon as a major component, silicon whose concentration inclines continuously so that the silicon concentration is the highest on the substrate side, and hydrogen whose concentration inclines continuously so that the hydrogen concentration is the lowest on the substrate side. Since the amorphous carbon film comprises the compositionally gradient film in which the silicon concentration inclines gradually so that the silicon concentration is the highest on the substrate side, the amorphous carbon film exhibits the highest hardness on the substrate side so that the substrate side can secure the strength of the amorphous carbon film. Additionally, since the amorphous carbon film comprises the compositionally gradient film in which the hydrogen concentration inclines continuously so that the hydrogen concentration is the lowest on the substrate side, the amorphous carbon film exhibits the lowest hardness on the outer side so that the aggressiveness against mating member is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a low friction sliding member with which the friction between a counterpart member and itself can be lowered even if the surface roughness of a sliding surface is large.
SOLUTION: The low friction sliding member 1 is constituted of a base material 11 and a sliding layer 21 which is formed on the sliding surface side of the base material 11 and brought into contact with the counterpart member formed in a sliding state. The sliding layer 21 is formed from amorphous carbon containing carbon as a main component, >30 to 2 -hybrid orbital is contained in an amount of 40-70 atomic% in the carbon. As the low friction sliding member 1 has a soft sliding layer 21, a sliding surface 21f can be made smooth by sliding even when the surface roughness of the sliding surface 21f is large. A wear resistant layer 22 formed from amorphous carbon containing hydrogen in an amount lower than that of the hydrogen contained in the amorphous carbon of the sliding layer 21 may be provided between the base material 11 and the sliding layer 21. The wear resistant layer 22 imparts a high wear resistance to the soft, low friction sliding member 1.
