  • Slide surface construction
    Patent number: 5401585
    Abstract: A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes (3hh0) oriented metal crystals with their (3hh0) planes (by Miller indices) oriented toward a slide surface. The content S of said (3hh0) oriented metal crystals is set in a range represented by S.gtoreq.40%. This makes it possible to provide a slide surface construction which has a predetermined hardness and an excellent wear resistance and ensures that the wearing of a mating member having a lower hardness can be suppressed.

  • Slide surface construction having oriented F.C.C. metal layer
    Patent number: 5376194
    Abstract: A slide surface construction is formed of an aggregate of Ni crystals having a face-centered cubic structure. The aggregate includes {311} oriented Ni crystals with their {311} planes (by Miller indices) oriented toward a slide surface. The content S of the {311} oriented Ni crystals is set in a range represented by S.gtoreq.40%. The {311} oriented Ni crystals are of a quadrangular pyramid shape on the slide surface, and provide good oil retention for the slide surface construction. Thus, the slide surface construction exhibits an excellent seizure resistance.
