Abstract
A slide surface construction is formed of a large number of truncated hexagonal pyramid-shaped metal crystals in a slide surface, with the area rate A of said truncated hexagonal pyramid-shaped metal crystals being in a range of 40%.ltoreq.A.ltoreq.100%. A top face of each of the truncated hexagonal pyramid-shaped metal crystals has a plurality of flat face portions, with a step provided between adjacent ones of the flat face portions. Each of the truncated hexagonal pyramid-shaped metal crystals is a (hhh) oriented metal crystal which has a body-centered cubic structure and whose (hhh) plane (by Miller indices) is oriented toward the slide surface.
