    Abstract: PURPOSE:To make the improvement in the quality of an overlay layer and the expansion of an application range by placing a facing material consisting of a specific compsn. on an aluminum alloy base material and subjecting the material to building-up under irradiation with a laser. CONSTITUTION:The facing material which is constituted of 10 to 70wt.% chromium, 0.3 to 3 wt.% carbon and the balance iron and unavoidable impurities is placed on the aluminum alloy base material and is irradiated with the laser to form a deposited metal layer. The iron base overlay layer is formed on the aluminum alloy base material in this way. The overlay layer which is high in hardness and heat resistance than the overlay layer of aluminum and copper systems is thus formed. The application range of the overlay hardening of the aluminum alloy parts is widened.

    Abstract: PURPOSE:To prevent concentration of pinholes and to prevent peeling of a cladding by welding layer by heating the Al-base composite material surface, forming a layer of an Al alloy percolated from the inside on the surface and then, cladding metal by welding on the Al alloy layer. CONSTITUTION:When the Al alloy is made to a matrix and the surface of Al-base composite material in which reinforcing material made of inorganic material is composed is heated to the temperature above the melting point of the Al alloy of the matrix and below the melting point or the decomposition temperature of the reinforcing material, the Al alloy matrix in the composite material is molten. At this time, gas absorbed in the reinforcing material in the composite material is exhausted and in accordance with it, the molten Al alloy is precolated on the surface and the Al alloy layer is formed on the composite material surface. Accordingly, the pinholes are not concentrated on the interface between the Al alloy layer and the composite material. In addition, at the time of cladding by welding, since cladding by welding is performed on the Al alloy layer, the gas is not exhausted from the inside of the inside composite material and cladding by welding material is joined firmly to the composite material via the Al alloy layer.

    Abstract: PURPOSE:To form a sprayed metal layer with high adhesive strength by spraying the particles of a molten metal on a substrate with the atomizing air heated to a high temp. when a metal is arc-sprayed on various substrates. CONSTITUTION:A DC voltage is impressed between a couple of wires 1 and 2 to be sprayed, an arc is produced between the tips to melt the wires 1 and 2 by the heat of arc, and atomizing air 4 is injected from an atomizing nozzle 3 behind the wire. The molten metal of the wires 1 and 2 are atomized by the atomizing air 4 into the particles 5, and injected on the substrate to form the sprayed layer resulting from the wires 1 and 2. In this case, an air hose 9 to be connected to the nozzle 3 is formed by the insulating material 11 and a sheath 10, a heater 12 of nichrome wire, etc., is arranged therein, the heater is energized, and the atomizing air passing through a passage 13 is heated to >=150 deg.C. As a result, the particles 5 are not cooled by the atomizing air, and a sprayed layer is formed on the substrate with high adhesive strength.
