摘要： PURPOSE:To obtain a metallic material with a film having improved corrosion resistance by irradiating laser beams on a thermal sprayed ceramic film formed on the surface of a metallic material to melt the ceramic film. CONSTITUTION:A film of ceramics such as metallic oxide, nitride or carbide is formed on the surface of a metallic material by a thermal spraying method. Laser beams are irradiated on the thermal sprayed film in an inert atmosphere to melt the film. By this treatment, a molten film causing no degeneration is formed, and many micropores in the film disappear. As the temp. of the film is increased, the structure is made dense, and a metallic material with a thermal sprayed film having improved corrosion resistance is obtd.

摘要： PURPOSE:To form firmly a powder film free from defects on the surface of a metallic substrate by coating the surface of the substrate with an alloy to form a film, keeping the substrate at a fixed temp., and irradiating laser beams on the film to melt-bond the substrate and the film together. CONSTITUTION:A self-fluxing alloy having a desired composition is sprayed on the surface of a substrate such as a steel material or a steel plate to form a film. The substrate having the formed film is kept at >=350 deg.C, and laser beams are irradiated on the film to heat the film to a temp. above the m.p. of the alloy. By this treatment, the metallic substrate and the film are melt-bonded together along the boundary. Since the irradiated part and the heated part close to the irradiated part are not rapidly cooled, the cracking of the film can be prevented. Since a hardened structure is not formed in the melt-bonded part and the heat-affected part, the toughness of the substrate is maintained.

摘要： PURPOSE:To restore and increase again the hardness of a thermally sprayed metallic layer which is decreased by the irradiation of a laser by subjecting the surface of a steel, etc. to a heat treatment under specific conditions after the irradiation of the laser in the stage of spraying thermally and forming the corrosion- and wear- resistant metallic film on said surface then irradiating the laser thereto to improve the adhesiveness of the thermally sprayed metallic layer. CONSTITUTION:The film is formed on the iron or steel material by spraying thermally a metal such as Cu, Ni, Co, Cr, Ti or Mo or the alloy thereof in order to improve the corrosion and wear resistance of said material. The laser is irradiated to the thermally sprayed film by which the thermally sprayed film is once melted and is secured to the iron or steel base to improve the adhesiveness of the thermally sprayed film and the iron or steel base material. The hardness of the sprayed film is decreased by the irradiation of the laser and therefore the iron or steel base is heated to >=350 deg.C to weld the film to the iron or steel base in the stage of irradiating the laser and thereafter the iron or steel material is heated to 200-700 deg.C and is air-cooled by which the intermetallic compd. and carbide are precipitated in the film and the hardness of the film is again improved.

摘要： PURPOSE:To facilitate the repair of the fittings and to economize the manpower and time of the exchange of fittings, by thermally spraying an Ni-base self-fluxing alloy on the contact surface between a plug and the plug-fixing fittings of a mandrel bar and by forming a thermally sprayed film layer on the above-mentioned contact surface. CONSTITUTION:When plug-fixing fittings 6 for attaching a plug 7 to a mandrel bar 5 are constituted of a plug-fixing part 9 and a connecting part 10 with the mandrel bar 5, the contact surface A between the plug-fixing part 9 and the plug 7 is locally worn. In order to repair this contact surface A, an Ni-base self-fluxing alloy (alloy in which Si and B are blended with Ni) is thermal sprayed to form a thermally sprayed film layer on the contact surface A. At this time, the thermally sprayed film layer is composed of an undercoat layer, an intermediate layer, and a top layer, and, as the undercoat layer and the top layer, Ni-base self-fluxing alloy layers are formed to about 100-700mu thickness, respectively, and a layer of Ni-base self-fluxing alloy with which hard grains of WC, etc., are blended is formed to 500-2,000mu thickness as the intermediate layer. By this method, respective operation efficiencies of mills can be improved and also rolling tool costs can be reduced.

摘要： PURPOSE:To easily and efficiently prevent the sticking of marine products to a propeller, by forming a thermally sprayed film of copper of a specific thickness on the external surface of a propeller structure for ships and applying sealing treatment to the above. CONSTITUTION:A thermally sprayed film of copper or copper alloy of 150-200mu thickness is formed on the external surface of a propeller structure for ships (stern tube bearing, propeller shaft, propeller). Further, as the thermal spraying material, that of >=about 99wt.% copper content is preferred. Subsequently, a synthetic-resin material having properties such as leachability, sea-water resistance, and wear resistance is allowed to adhere to the above-mentioned thermally sprayed film to 20-30mum thickness to apply sealing treatment. In this way, the treatment for preventing the sticking of marine products to a propeller for ships can be easily performed.

摘要： PURPOSE:To obtain a hearth roll for a heat treating furnace having superior wear and build-up resistance at high temp. by forming a thermally sprayed coat of cermet consisting of Mo and ZrO2 on the surface of the substrate of a hearth roll. CONSTITUTION:A thermally sprayed coat of cermet consisting of Mo and ZrO2 is formed on the surface of the substrate of a hearth roll made of heat resistant cast steel or the like. The volume ratio of Mo to ZrO2 in the cermet is about 20:80-80:20, preferably about 40:60-50:50. The coat is stripped because it has superior adhesion to the substrate and the coat also has superior strength at high temp. Thus, a hearth roll having superior wear and build-up resistances at high temp. and a long service life is obtd.
