Abstract
PURPOSE: To obtain the composite powder which is useful for electrical contact material and consisting of a solidified mixture containing metallic particles dispersed uniformly and minutely in a silver matrix by a method wherein a mixture of silver powder and powder of metals having no solid solubility for silver is flame sprayed with gas and is then quenched.
CONSTITUTION: The silver powder and the powder of at least one metal A having no solid solubility for silver, such as Ni, Cr, Fe, Co, W, Mo or the like are mechanically mixed with each other. The powder mixture is placed in a powder container 2, is introduced into a gas pipe 5 of a burner 4 such as an acetylene burner and is conveyed to a nozzle 6 by oxygen-acetylene carrier gas. Then the powder mixture 1 is flame sprayed through the combustion of acetylene at the nozzle 6. The molten mixture of silver and the metal A thus sprayed is introduced into a water tank 7 and is solidified by quenching it in water 8 to obtain the composite powder 9. By using the composite powder 9 thus treated, an electrical contact having excellent resistance to fusion and low contact resistance and the like can be manufactured.
