A slide member comprises a slide portion, the surface of which comprises an aggregate of crystals of a lead alloy having crystal planes directed towards said slide surface whereby to form at least part of said surface. The aggregate comprises first oriented crystals 13, having a (h00) plane directed towards said surface and, optionally, second oriented crystals having (111) and (222) planes directed towards said surface, crystal surfaces being provided by (h00) planes, the relative abundance of said first oriented crystals as determinable by X-ray diffractometry being at least 60% as expressed by the ratio I(a)/(I(a)+I(b)> where I(a) and I(b) are the integrated intensities for diffraction peaks correspondingly to the first and second oriented crystals respectively. Such slide members have improved properties in terms of wear resistance, strength, and seizure resistance. <IMAGE> |
