The preparation method of copper base electrode powder deformation composite material adopts the elementary powder Cu and Cr or W and Cu as raw material, and adopts the following steps: first step, making mechanical ball-grinding to make powder; second step, cold-pressing and making blank; third step, vacuum solid phase sintering; and fourth step, thermal static liquor extruding. Said invention also adopts the graphite and glass mixture as lubricating agent, and the volume ratio of graphite… CONTINUE READING
