Abstract The La-doped nanocomposite AgSnO₂ contact alloys are prepared by chemical coprecipitation, high-energy ball milling and general sintering technique. The effects of La doping on properties including the mechanic property, microstructures, and arc erosion products of electrical contact alloys are investigated respectively. Results show that the enrichment zone of Ag and SnO₂ are significantly prevented when La is added. Furthermore, the splash of Ag is slight, and arc erosion characteristic of AgSnO₂ transforms ‘spray' into ‘evaporation' with increasing doping concentration.

Key words： La-doped AgSnO nanocomposite arc erosion
