ABSTRACT:
A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes {222} oriented Fe crystals with their {222} planes by Miller indices oriented toward a slide surface. The content S of the {222} oriented Fe crystals is in a range represented by S.gtoreq.20%, preferably in a range represented by S.gtoreq.40%. The {222} oriented Fe crystals form a trigonal pyramid shape on the slide surface, which provides good oil retention for the slide surface construction. Thus, the slide surface construction exhibits an excellent seizure resistance.
