Abstract
PURPOSE: To improve electric contact-point material in resistance against abrasion due to discharge by a method wherein a specific amount of one or more additional elements of Si and Ge is finely dispersed into Ag and is internally oxidized.
CONSTITUTION: One or more of Ge and Si in 10'17 atomic % is added as solute element to Ag and finely dispersed. This ingot is hot-processed to form into a specified shape and is internally oxidized under atmosphere at a temperature between 250°C and eutectic point. The method easily provides an electric contact-point material which maintains contact properties such as resistance against sticking and contact resistance, and has extremely improved wear resistance.
