Abstract
A slide surface construction is formed of an aggregate of Ni crystals having a face-centered cubic structure. The aggregate includes {220} oriented Ni crystals with their {220} planes (by Miller indices) oriented toward a slide surface and having a content S in a range represented by S<25%. If the content of the {220 } oriented Ni crystals is set in such a range, a large number of quadrangular Ni crystals are precipitated in the slide surface, so that the oil retention and the initial conformability are improved by the Ni crystals. Thus, the slide surface construction exhibits an excellent seizure resistance.
