摘要
金属氧化物增强Ag基合金材料,由于具有优良的导电性、抗电弧性能而成为一种重要的电接触材料。利用内氧化法制得内氧化型AgCu_4Ni_(0.3)合金材料。CuO,NiO颗粒弥散分布于Ag基体中。提高了材料的力学性能、再结晶温度及耐磨性能,导电性能略有下降。材料成功用于微电机换向器。
The internal oxidized Ag-based alloys are widely used in the electrical contact field because of their excellent electrical and arc resistance. Oxidized AgCu_4Ni_(0.3) alloy was prepared. The Cu O and Ni O particles distributed in the matrix dispersively. Mechanical property,recrystallize temperature,wear-resisting property of the oxidized alloys were increased obviously,and the electrical property were decreased lightly. Oxidized alloys were used successfully in micro-motor commutator.
