Title (EN) SLIDING MEMBER
(FR) ÉLÉMENT GLISSANT
(JA) 摺動部材
Abstract:
(EN) Provided is a sliding member having excellent abrasion resistance and high hardness in an environment in which a high load is applied. With this sliding member the surface of a sliding layer that supports an object to be slidably moved is subjected to a shot blast process, and a sliding surface having a concavo-convex shape with an arithmetic mean roughness (Ra) of 1.0-2.5 μm, a ten-point mean roughness (Rz) of 5.0-10.0 μm, and a surface hardness (Hv) of 220-250 is formed on the surface of the sliding layer.
(FR) L'invention porte sur un élément glissant ayant une excellente résistance à l'abrasion et une haute dureté dans un environnement dans lequel une forte charge est appliquée. Avec cet élément glissant, la surface d'une couche glissante qui supporte un objet qui doit être déplacée de façon glissante est soumise à une opération de grenaillage, et une surface glissante ayant une forme concavo-convexe qui présente une rugosité moyenne arithmétique (Ra) de 1,0-2,5 µm, une rugosité moyenne sur dix points (Rz) de 5,0-10,0 µm et une dureté de surface (Hv) de 220-250 est formée sur la surface de la couche glissante.
(JA)  高荷重が掛かる環境下に適した硬度を持ち耐磨耗性に優れた摺動部材を提供する。 被摺動物を摺動可能に支持する摺動層の表面にショットブラスト処理が施され、摺動層の表面に、算術平均粗さ(Ra)が1.0~2.5μm、十点平均粗さ(Rz)が5.0~10.0μm、表面硬度(Hv)が220~250の凹凸形状を持つ摺動面が形成された摺動部材である。
