Электроконтактный Материал На Основе Серебра, Дисперсноупроченный Оксидами Цинка, Олова И Титана

Abstract

A new electrocontact materal based on silver has been obtained. The material has been dispersion-strengthened by nanopowders of zinc oxide, stannum oxide and titanium oxide. The microstructure and elemental composition of the phases have been formed at solid-phase sintering and electroerosion tests have been studied by the methods of scanning electron microscopy and energy-dispersive X-ray spectroscopy. The electroerosion wear and transitional resistivity have been determined as a result of laboratory testing. The developed electrocontact materal has demonstrated physical, mechanical and exploitational properties similar to the properties of an electrocontact materal based on toxic cadmium oxide
