A bearing surface having microasperities is treated by a process comprising the steps of generating a high density energy beam and producing relative motion between the beam and the bearing surface to define a succession of points at each of which the beam impinges upon the bearing surface for an interaction time during which localized heating occurs and then rapid cooling begins to cause partial melting followed by rapid solidification, that, in the direction normal to the bearing surface extends to a depth less than the microasperity height and that, owing to said relative motion, extends throughout an area of the bearing surface to define a microdimpled surface.
