Abstract

Abstract In this study, the arc-erosion performances of AgSnO 2 -based electrical contact materials containing different amounts of titanium dioxide (TiO 2 ) were investigated using the mechanical alloying-assisted powder metallurgy method. For this purpose, composite powder synthesis was carried out through grinding experiments using a planetary ball mill, and the produced composite powders were subjected to molding and vacuum sintering processes. Subsequently, electrical wear tests were carried out under inductive loads to investigate the arc-erosion performance of composites. Scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and laser diffractometry techniques were used to…
