MANUFACTURING METHOD FOR CERAMIC DISPERSED STRENGTHENED COPPER USING MECHANICAL ALLOYING METHOD

摘要

Purpose: a kind of method is used to be arranged to by the welding of mechanical alloying method to increase conductivity and hardness for manufacturing ceramics dispersion reinforced copper electrode. Construction: the manufacturing method of ceramics dispersion reinforced copper electrode includes the first step, and wherein copper powder/copper alloy powder, ceramics and manufacture process control agent are entered so as to executing agency's alloying in a ball mill; The second step in the place that the powder raw material that tank obtains in the first step is performed; Third step is combined to one preform of manufacture by cold application on canned raw material here; 4th step is input for the room of degasification in a vacuum on preform here; The place that one the 5th step is vented to preform be hot pressing go out to manufacture a ceramics-dispersion reinforced copper welding rod; Copper electrode bar is cut in the 6th step in the place of a predetermined length; 7th step, the copper electrode bar and copper alloy handled here are cast bonding.
