摘要
The present invention is mainly used as an electrode material or materials for contact spot welding for high temperature is generated during welding resistance is large at the same time as the dispersion strengthened copper alloy according occupy a very important position as an industrial material with a high electrical conductivity, and more particularly, especially the manufacturing process is simple, handling, compared to the alloy powder produced by a conventional internal oxidation This would facilitate the wider of the mechanical method of producing an aluminum oxide dispersion strengthened copper alloy powder using a chemical mechanical process that can manufacture the alloy having an electrical characteristic and a dispersion strengthened copper alloy powder prepared according to the method and. Method for producing the aluminum oxide dispersion strengthened copper alloy powder, but is composed of copper powder and aluminum dioxide powder and copper powder as a raw material, the molar ratio of copper powder and aluminum dioxide powder, 2 to 4: Determination of the total raw material to 1 to 3 the method comprising: loading the mixture stirred; See the stirred raw material - which is sealed and then charged to the mill, a ball in an inert atmosphere - to induce a mechanochemical reaction by applying mechanical energy by the mill and a step of synthesizing the dispersion strengthened copper alloy powder. This method of synthesis via a dispersion strengthened copper alloy powder is resistant to the high temperatures generated during welding, which has a high electrical conductivity at the same time large industrial materials, that is superior can be effectively used up electrode material or a contact material for a spot welding it is effective.
