ABSTRACT:
A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes at least one of two types of metal crystals selected from the group consisting of (1) (h00) oriented metal crystals with their (h00) planes (by Miller indices) oriented toward a slide surface and having a content S in a range represented by S<25%, and (2) (3hh0) oriented metal crystals with their (3hh0) planes (by Miller indices) oriented toward the slide surface and having a content S in a range represented by S<25%. If both the types of the oriented Fe crystals are present, a large number of trigonal pyramid-shaped Fe crystals are precipitated in the slide surface, thereby providing improved oil retention and initial conformability. Thus, the slide surface construction exhibits an excellent seizure resistance.
