Abstract:

The internal oxidized Ag-based alloys are widely used in the electrical contact field because of their excellent electrical and arc resistance. Oxidized AgCu₄Ni_0.3 alloy was prepared. The CuO and NiO 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.

Key words: internal oxidation, AgCu₄Ni_0.3 alloy, wear-resisting property, micro-motor commutator
