Title (EN) SLIDING MEMBER
(FR) ÉLÉMENT COULISSANT
(JA) 摺動部材
Abstract: front page image
(EN)A sliding member (11) is provided with a substrate (12) and an overlay layer (13) superposed on the substrate (12). The overlay layer (13) has, arranged in the thickness direction, a plurality of regions from a region (13a) on a sliding surface (14) side, where sliding with a counterpart member occurs, to a region (13b) on the substrate (12) side. The material for forming the overlay layer (13) has a plurality of crystal planes. The orientation index of at least one crystal plane of the plurality of crystal planes differs between the region (13a) on the sliding surface (14) side of the overlay layer (13) and the region (13b) on the substrate (12) side of the overlay layer (13).
(FR)La présente invention se rapporte à un élément coulissant (11) qui est pourvu d'un substrat (12) et d'une couche de recouvrement (13) superposée sur le substrat (12). La couche de recouvrement (13) présente, une pluralité de régions agencées dans le sens de l'épaisseur depuis une région (13a) côté surface coulissante (14), sur laquelle se produit le coulissement avec un élément conjugué, jusqu'à une région (13b) côté substrat (12). Le matériau permettant de former la couche de recouvrement (13) présente une pluralité de plans cristallins. L'indice d'orientation d'au moins un plan cristallin de la pluralité de plans cristallins est différent entre la région (13a) côté surface coulissante (14) de la couche de recouvrement (13) et la région (13b) côté substrat (12) de la couche de recouvrement (13).
(JA)摺動部材11は、基材11と、基材11に重ねて設けられているオーバレイ層13とを備える。オーバレイ層13は、厚さ方向に相手側部材と摺動する摺動面14側の領域13aから基材12側の領域13bまで複数の領域を有している。オーバレイ層13を形成する材料は、複数の結晶面を有している。複数の結晶面のうち少なくとも一つの結晶面の配向指数は、オーバレイ層13の摺動面14側の領域13aと基材12側の領域13bとで異なっている。
