Abstract
A slide surface construction of a slide bearing is formed of an aggregate of two different metal crystals. The sliding condition of a first region of the slide bearing is more severe than that of a second region. The (2hhh) oriented metal crystals having a body-centered cubic structure with their (2hhh) planes (by Miller indices) oriented toward a slide surface exist in the first region. The content S.sub.2hhh of the (2hhh) oriented metal crystals is set in a range of S.sub.2hhh .gtoreq.20%. These crystals have a high hardness and are in the form of fish-like metal crystals in the slide surface and hence, an aggregate of these metal crystals has a good oil retention. The (hhh) oriented metal crystals having a body-centered cubic structure with their (hhh) planes (by Miller indices) oriented toward a slide surface exist in the second region. The content S.sub.hhh of the (hhh) oriented metal crystals is set in a range of S.sub.hhh .gtoreq.40%. These crystals are in the form of hexagonal pyramid-shaped metal crystals and hence, an aggregate of these metal crystals has a good oil retention. Thus, it is possible for the two regions with different sliding conditions to exhibit an excellent sliding characteristic.
