摘要： The invention relates to a molten metal plating apparatus (10) comprising a roller (24) rotatably supported by a bearing in a molten metal bath (26), the roller having a shaft sliding portion (28), the bearing (29) having a sliding portion (51), both the shaft sliding portion and the sliding portion being made of ceramic sintered body (32, 51), at least one if both the shaft of the roller and the bearing being made of a ceramic sintered body containing a solid lubricating material. The invention also relates to a die casting machine having a sleeve and a plunger tip both made of ceramic sintered bodies at least one of which contains a solid lubricating material. The bearing for the roller, the sleeve and the tip may be formed of a composite body having a ceramic sintered body portion and and a metal portion secured and fitted thereto by an intermediate member (34) which is elastically and plastically deformed at the time of the usage. The composite structure formed by fitting is usable for other applications.

摘要： A continuous hot-dip plating apparatus comprises a roll assembly (14, 15) having superior resistance to erosion caused by the hot melt (16) of the plating metal, as well as high resistance to wear of the sliding portions of roll shafts (18) and bearings (19) which are used in the hot melt (16) of the plating metal. A ceramics is mounted on the sliding portions of the metallic roll shafts (18) making sliding contact with the metallic bearings (19) and/or on the sliding surfaces of the metallic bearings (19) which slidingly contact the sliding portions of the metallic roll shafts (18). The material of the ceramics serving as a sliding member is selected taking into account the wettability to the hot melt (16) of the plating metal. At least one of each, the sliding portion of the metal roll shaft (18) and the sliding surface of the associated bearing (19) is provided with a ceramic material which exhibits a large wettability to the hot melt (16) of the plating metal.
