    Abstract: In order to improve conformability of a sliding surface of a sliding member in an early state of sliding, there is provided a sliding member in which a plurality of holes are formed on a sliding surface, and the diameters (or the opening area) of the holes on the sliding surface are arranged so as to become gradually large as it gets closer to both ends in an axial direction from the center side in the axial direction. This feature decreases the pressurized area as it gets closer to the ends of the sliding surface so that it wears at an early stage, whereby a conformed surface following the deflection of a mating member is provided.

    Abstract: Disclosed is a sliding member having a bearing alloy layer, an intermediate layer of Ni or a Ni alloy formed on the bearing alloy layer, and an overlay layer of a Sn alloy containing Cu formed on the intermediate layer. There exist SnnullCu compounds in the overlay layer, which protrudently extend from the intermediate layer. The hard SnnullCu compounds contribute to the overlay layer in improving fatigue resistance property. A soft Sn matrix being rich in an outer surface region of the overlay layer is responsible for keeping good conformability to have excellent anti-seizure property.

    Abstract: A method of manufacturing a multilayer material including a back metal and a metal plate made from a metal differing from the back metal is disclosed. The method includes heating powder of the metal formed into the metal plate in a reducing atmosphere so that an oxide on a surface of the metal powder is deoxidized, and spreading the deoxidized metal powder onto the back metal and irradiating laser beam having an energy density of 10 to 100 kW/cm2 onto the metal powder spread on the back metal so that the metal powder is partially heated to be melted, while the laser beam is moved relative to the spread metal powder, and quenching the melted part of the metal powder at an underside of the back metal so that the melted part is rapidly solidified, whereupon the multilayer material has a dendritic structure in which the metal plate extends substantially vertically from a surface of the back metal, and the dendritic structure has a crystal grain size equal to or smaller than 0.02 mm at a cut surface thereof parallel to a surface of the back metal and/or a dendritic arm spacing equal to or smaller than 0.02 mm at a cut surface thereof vertical to the surface of the back metal.
