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 ~ 20%, preferably in a range represented by S ~ 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.
La présente invention a pour objet une surface de frottement constituée d'un agrégat de cristaux de Fe à réseau cubique centré. L'agrégat en question comporte (222) cristaux de Fe dont les (222) plans par indices de Miller sont orientés vers la surface de frottement. La teneur en S des (222) cristaux de Fe orientés est de l'ordre de S 20 % ou, préférablement, de l'ordre de S 40 %. Les (222) cristaux de Fe orientés forment une pyramide trigonale à la surface de frottement, ce qui confère de bonnes caractéristiques de rétention d'huile à la surface de frottement. La surface de frottement ainsi obtenue offre une excellente résistance au grippage.
