Abstract
A slide member having a highly lubricative and highly abrasion-resistant plating layer formed on the sliding surface thereof. The plating layer contains fine particles of graphite selected from flake graphite, vein graphite and/or amorphous graphite in its metallic matrix. The plating layer has a hardness of not less than 550 in terms of Hv and is produced by using a plating solution containing naphthalene sulfanate of formalin condensate as surface active agent. The matrix is preferable to be a Ni--P type metallic matrix and the dispersed fine particles of graphite are preferable having a size of 0.1 to 20 .mu.m and are contained by 0.1 to 10 wt % relative to the matrix.
