PURPOSE:To obtain a steel member having superior rolling fatigue resistance by roughening the carburized, hardened and tempered surface of a steel member and implanting nitrogen ions into the roughened surface. CONSTITUTION:The surface of a steel member such as a bearing member is carburized by gas, solid or liq. carburization, hardened and tempered to form a carburized layer having about 2% C content. The surface of this layer is roughened to -8X10 ions/cm . A steel member such as bearing member hardly causing pitting and having superior rolling fatigue resistance can stably be produced.

PURPOSE:To prevent the overheating of a sprayed deposit and to prevent various disadvantages due to overheating by forming a sprayed deposit while applying cooling to the internal surface of a cylinder bore by introducing a refrigerant into a passage formed by covering the opening of a cooling jacket. CONSTITUTION:The opening of a cooling jacket 3 provided to the periphery of a cylinder bore 2 is covered, e.g. with a cover plate 4, by which a passage connecting one end of the above jacket 3 to the other end is formed. A material having wear resistance and corrosion resistance is thermally sprayed while applying cooling to the internal surface of the above cylinder bore 2 by introducing a refrigerant into the above passage by which a sprayed deposit is formed. By this method, the cooling effect is increased and the overheating of the sprayed deposit can be prevented, and the shape precision of the cylinder bore can be improved.

PURPOSE:To obtain a Ti-Al alloy material excellent in oxidation resistance by providing an Al pack cementation layer to the surface of a base material composed of Ti-Al alloy and further forming a pure Al film of specific thickness on the above layer. CONSTITUTION:An Al pack cementation layer is provided to the surface of a base material composed of Ti-Al alloy. The above treatment layer can be formed by filling a vessel with the above base material together with a diffusion agent cinsisting of Al powder, Al2O3 powder, and HN4Cl powder and carrying out heating at about 1100 deg.C. A pure Al film of 5-30mum thickness is formed on the above treatment layer. This pure Al film is formed by a hot dipping method, a PVD method, such as vacuum vapor deposition and ion plating, etc. By this method, the Ti-Al alloy material excellent in oxidation resistance can be obtained.

PURPOSE:To improve fatigue strength at desired position of surface of a casting by adding residual stress after rapidly melting and rapidly solidifying the surface layer of the casting. CONSTITUTION:In the casting 1 of Al alloy, cast iron, spheroidal graphite cast iron, etc., by impressing high density heating energy 2 of TIG arc, laser beam, etc., the surface layer is rapidly melted and rapidly cooled and solidified. The surface of this re-solidified layer 4 is finished to the smooth surface 5 with cutting machine, etc. Successively, treatment of shot material 6 is injected and collided, etc., is executed and plastic flowing is developed on the most outer surface layer 4A of the re-solidified layer 4, to execute work hardening to there and the residual compression stress is given to the layer 4B at inside thereof. By this method, the service life of the casting parts, such as applying big repeated bending load can be extended.

PURPOSE:To produce the title Al-based sliding member having excellent resistance to wear and seizing, etc., by alloying Sn on the surface of an Al alloy base metal, and forming a layer of the Al-Sn alloy having a specified content of Sn. CONSTITUTION:An Sn coating layer is formed by thermal spraying, plating, etc., on the surface of the region of an Al alloy base metal where wear resistance is required. High-density energy such as a laser beam is then impressed on the Sn on the Al alloy base metal to rapidly melt the Sn and the base metal surface, hence the Al and Sn are fused together, and the layer of an Al-Sn alloy contg. 5-30wt.% Sn is obtained. By this method, an Al-based sliding member having excellent resistance to wear and seizing is obtained, and utilized as automobile parts, etc.

PURPOSE:To decrease the alloy element content in the surface layer of a casting to be formed with a plating layer so that the excellent plating layer having good adhesiveness and less defects such as pinholes can be formed by previously alloying pure Al, etc., to the surface of the above-mentioned casting by high- density heating energy. CONSTITUTION:The pure Al or the Al alloy contg. the Al at the ratio higher than in the Al alloy casting 1 is disposed as the alloying material 2 on the surface 1A in the plating layer forming part of the casting 1 by thermal spraying, etc., and the high-density heating energy 3 such as electron beam is impressed thereto from above to simultaneously melt the material 2 and the surface 1A on the lower side thereof. A molten pool 4 is rapidly solidified by the movement of the position where the energy 3 is impressed. The alloyed layer 5 which is decreased in the alloy element content, i.e., crystallized matter, etc., is fined in the crystallized matter and has the decreased casting defects is thus formed. The excellent plating layer having the good adhesiveness and the decreased defects is thereby formed.

PURPOSE: A bonding structure of a non-metal member and vulcanized rubber excellent in bonding strength, obtained by bonding the non-metal member and the vulcanized rubber by interposing copper between the bonding surfaces thereof. CONSTITUTION: A non-metal member 1 such as an epoxy resin or a polyester resin and vulcanized rubber 3 such as isoprene rubber or butyl rubber are bonded by interposing copper 11 between the bonding surfaces thereof. As copper allowed to exist between the bonding surfaces, a copper alloy such as brass may be used and copper or the copper alloy may be used in a powdery or fibrous form or may be a fiber which is dispersed in the non-metal member 1 but exposed by polishing the bonding surface of said member 1 and, in carbon fiber reinforced plastic, copper may be vapor deposited on the surface of the carbon fiber. By this method, copper 11 present between the bonding surfaces 12 is reacted with sulfur contained in the vulcanizing agent of the vulcanized rubber to form copper sulfide and chemical bonding force is generated between the non- metal member 1 and the vulcanized rubber 3 to strongly bond both of them.
