Effect of the content and dispersivity oxides on the erosion resistance and resistance to the welding of the contact from the composite materials on the silver base

Abstract

The effect of the cadmium and tin oxide content (from 10 to 25 mass.%) and its dispersivity (from 0,1 to 17 (from 0,1 to 17μm) on the erosion resistance and resistance to the welding of the contacts made of the composite materials of the silver–tin oxide, silver–cadmium oxide systems has been studied. It was shown that increasing of materials resistance to electric erosion as role is followed by decreasing of contacts resistance against welding. For recognizing of optimal field of uses of Ag–MeO materials with different dispersivity and mass content of oxides in silver is worthwhile the performance of endurance test of these materials in real commutative apparatus
