ABSTRACT:
A slide surface construction is formed of an aggregate of metal crystals on a surface of a slide member. The area rate A of pyramid-shaped metal crystals in the slide surface is in the range of A.gtoreq.40%, and the oxygen (O) content and/or the phosphorous (P) content in the aggregate is in a range of 0.gtoreq.0.2% by weight and P.gtoreq.0.04% by weight. The slide surface takes on an intricate aspect due to the presence of the large number of hexagonal pyramid-shaped metal crystals and hence, has a good oil retention. In addition, the wearing of the hexagonal pyramid-shaped metal crystals is inhibited by an increase in hardness caused by the oxygen contained, and therefore, the oil retention is maintained. Thus, the slide surface construction exhibits an excellent seizure resistance. In addition to oxygen (O) and/or phosphorous (P), the elements that may be added to the aggregate include hydrogen (H), carbon (C) and boron (B).
