【Abstract】 A CO2 Laser was used to sinter the copper-matrix green compact,interdiffsion of elernents occured,forming the novel phases such as e and η which could hardly be seen by conventional sintering. The properties of sintered material were measured,the results were that density,wear resistance and impact toughness were much higher than the convertional sintering.更多还原
