ABSTRACT:
The present invention relates to an article having an insulation abrasion-resistance coated layer composed of glass ceramics containing a given amount or more by weight at least either of oxides of divalent alkaline earth metals of a group composed of BaO, MgO, CaO and ZnO and containing a given amount or less the oxides of univalent alkali metal of a group composed of Na.sub.2 O, K.sub.2 O and Li.sub.2 O on the surface of the metallic base body. As it may be used in bearing, mechanical seal and tape guide post, the abrasion-resistance of the sliding portion may be improved.
