    Abstract: Disclosed is a sliding member having a bearing alloy layer and a composite plating film provided on the bearing alloy layer. The composite plating film is made of a lead alloy containing 0.1 to 10 mass percent in total of copper and 0.3 to 25 volume percent in total of co-deposited inorganic particles. The outermost surface layer of the composite plating film, which has a thickness proportion of 10 to 40% to the entire thickness of the composite plating film, does not contain inorganic particles and copper. The lower layer of the composite plating film contains Cu and inorganic particles, such as Si3N4, dispersed therein.

    Abstract: A Bi base material of which a Miller index (202) face has the index of orientation of not less than 30% and in which the (202) face has the index of orientation assuming a maximum value as compared with those of other faces forms a minute structure and has a surface which is not a mirror finished surface but a fine, irregular surface on which minute and uniform projections in the form of a triangular pyramid or a quadrangular pyramid congregate. Therefore, the surface easily retains oil thereon to be improved thereby in oil wettability, as a result of which an improvement in anti-seizure is achieved.

    Abstract translation: 具有米勒指数（202）面的Bi基材料具有不小于30％的取向指数，并且其中（202）面具有与其它表面相比具有最大值的取向指数的Bi基材料形成 并且具有不是镜面加工表面的表面，而是具有三角锥形或四角锥形集合的微小且均匀的突起的细小的不规则表面。 因此，表面容易保持油在其上，从而提高油的润湿性，其结果是可以实现抗咬住性的提高。

    Abstract: In order to enhance the fatigue resistance and the anti-seizure property while maintaining the embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer is provided with a recess “a” and protrusions “b”, thereby being made into a textured uneven surface. The protrusion has the shape of a oblique square at 45° relating to the circumferential direction, so that when a foreign particle X introduced between sliding surfaces of a shaft and the plain bearing is moved in the circumferential direction in accordance with the rotation of the shaft, the foreign particle X runs against a side edge of the protrusion “b” and moves along the side edge, thereby the embedding of the foreign particle X is promoted. If the foreign particle fails to be adequately embedded, the foreign particle leaves the side edge again.

    Abstract: In order to provide a plain bearing excellent in the anti-seizure property, a bearing metal layer is provided with a plurality of recesses different in depth on the inner surface thereof so as to form an uneven textured portion thereon, the recesses being filled with a soft overlay layer. At the beginning of the use, the overlay layer develops the conformability. When the wear proceeds to the wear level I so that the shallow recesses disappear, an intermediate layer or the bearing metal layer forming protrusions is exposed and form a condition in which the overlay is mixed. Furthermore, when the wear proceeds to the wear level II, the shallow recesses disappear while the deep recesses remain, so that the condition hardly to cause the seizure is maintained.

    Abstract: Disclosed is a plain bearing comprising a back metal, a bearing alloy layer provided on the inner surface of the back metal, an intermediate layer provided on the bearing alloy layer and an overlay provided on the intermediate layer. The bearing alloy layer has a textured uneven inner surface, comprising a number of protrusions, which has been formed by etching of the inner surface provided with a mask. A feature and a pattern of the uneven surface can be optionally and accurately formed by designing appropriately the mask. For example, the protrusions may be a form of square, circle or lozenge cross-section, or a ridge extending in an optional direction, e.g. circumferentially, perpendicularly or obliquely to the circumference. After the overlay considerably wears, there will appear a surface state in which the bearing alloy layer, the intermediate layer and the residual soft overlay in the etched recess coexist.

    Abstract: Disclosed is a plain bearing having a back metal, a bearing alloy layer and an overlay layer, in which the bearing alloy layer and the overlay layer are formed on the inner surface of the metal in this order. The inner surface of the bearing alloy is provided with circumferential broad width recesses and narrow recesses in which the overlay material is filled. The fatigue resistance and were resistance are ensured by the zone of the narrow width recesses. The plain bearing exhibits high embeddability for a foreign substance by presence of the zone of the broad width recesses.
