| titleOfInvention | Preparation method of silver-copper-oxide electrical contact material |
| abstract | The invention discloses a preparation method of a silver-copper-oxide electrical contact material, which comprises the following steps: 1 weighing oxide powder and abrading-ball respectively and processing the weighed oxide powder through the high energy ball milling method to obtain a nanometer level oxide powder; 2 mixing a silver powder, a copper powder and a nanometer level oxide powder obtained from step 1 to obtain a mixed powder A, and conducting mechanical alloyage surface treatment to the mixed powder A to obtain a mixed powder B; and 3 conducting procedures of annealing, moulding, sintering and extruding to the mixed powder B obtained from step 2 to obtain the silver-copper-oxide electrical contact material. According to the preparation method of the silver-copper-oxide electrical contact material, the cheap metal copper is used to substitute partial precious metals silver; at the same time, oxide is added to prepare the electrical contact material; in this way, not only the preparation cost is low; the obtained electrical contact material has good conductive performance and long service life. |
