摘要： Herein disclosed is a process for forming a dispersion alloy layer on a metallic base. The powder of an alloy system, which will separate into two or more multi-liquid phases at a temperature equal to or higher than its melting point and will solidify, when quenched, with its individual liquid phases being separate and in which the ratio of the minimum to the maximum specific weight its individual liquid phases is 0.3 or higher, such as the powder of any alloy system of Cu-Ni(15%)-Fe(8%)-Si(3%)-B(1.5%) is applied to a metallic base. The powder thus applied is then melting and agitated while being irradiated with a laser beam oscillated. The agitated melt of the powder is then quenched to solidify with the movement of the laser beam thereby to form on the metallic base the dispersion alloy layer in which the solid particles of at least one of those phase such as silicide particles are dispersed in the matrix of the remaining one of the phases.

摘要： This internal combustion engine cylinder head includes a main portion made substantially from aluminum alloy and having a valve port which has a circumferential valve seat surface for cooperation with a poppet valve to open and close communication through the valve port. A cladding layer is formed of copper alloy claddingly laid upon this valve seat surface, and an intermediate alloy layer is present between the copper alloy cladding layer and the main cylinder head portion, this intermediate alloy layer being composed essentially of an alloy between the aluminum alloy of the main cylinder head portion and the copper alloy of the cladding layer. Thereby, the anti-wear properties of the valve seat are desirably improved without making the fabrication process unduly troublesome or costly. The proportion of aluminum diffused into the copper alloy cladding layer from the main portion of the cylinder head should preferably be not more than about 15%. The thickness of the intermediate alloy layer should preferably be between about 5 microns and about 300 microns, and the thickness of the copper alloy cladding layer should preferably be at least about 50 microns. If "x" denotes the thickness of the intermediate alloy layer in microns, this thickness value being between about 5 and about 300, and if "y" denotes the thickness of the copper alloy cladding layer in mm, then preferably the relationship y=1.5254x+42.373 should at least approximately hold.

摘要： In forming a weld bead of pure copper on a ferroalloy base material by laying a powder of copper and melting the powder by a high density energy source such as laser beams, TIG arc or electron beams, the powder of copper is beforehand mixed with a powder of an auxiliary metal having a higher melting point than pure copper. In order to ensure the substantial purity in copper of the weld bead, the powder mixture should not include more than 16 wt % nickel.

摘要： In this method for forming an alloy layer on the surface of an aluminum alloy substrate, a powder for alloying, containing a substance to be alloyed with the substrate and an element selected from the group consisting of silicon and bismuth, is disposed upon the surface of the aluminum alloy substrate. This powder is then irradiated with a CO.sub.2 laser, so as to be melted and fused together with a surface portion of the aluminum alloy substrate, so that these two are alloyed together. The powder for alloying may be a powder of an alloy of the substance to be alloyed with the aluminum alloy substrate and the element selected from the group consisting of silicon and bismuth, or alternatively may be a mixture of a powder of the substance to be alloyed with the aluminum alloy substrate and a powder of the element selected from the group consisting of silicon and bismuth.
