Summary: | [Problem] To provide a sliding member equipped with an overlay such that good fatigue resistance can be achieved while preventing peeling between layers. [Solution] A sliding member is provided with an overlay formed of a Bi-Sb alloy film, and is characterized in that the concentration of Sb in the overlay increases with depth from the surface thereof.
Le problème décrit par la présente invention est de fournir un élément coulissant doté d'un revêtement de sorte qu'une résistance à la fatigue satisfaisante puisse être obtenue, tout en empêchant un pelage entre les couches. La solution selon l'invention porte sur un élément coulissant qui est pourvu d'un revêtement formé d'un film d'alliage de Bi-Sb, et qui est caractérisé en ce que la concentration de Sb dans le revêtement augmente proportionnellement à la profondeur à partir de la surface de ce dernier.
【課題】層間の剥離を防止しつつ良好な耐疲労性を実現可能なオーバーレイを備えた摺動部材を提供する。 【解決手段】BiとSbの合金めっき被膜によって形成されたオーバーレイを備えた摺動部材であって、前記オーバーレイにおいて、表面からの深さが深くなるにつれてSbの濃度が高くなる、ことを特徴とする。 |
