Title:
ELECTRIC CONTACT MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/014949
Kind Code:
A1
Abstract:
In silver-oxide electric contact materials, there has been the problem of oxides being deposited on the contact surface by repeated electrical opening/closing, resulting in contact resistance at the contact surface and causing a temperature increase. Therefore, the disclosed electric contact material is characterized by forming at least one of 1-99 mass% Ag-W, 1-99 mass% Ag-WC, W or WC as at least one coating layer on the contact surface of the silver-oxide electric contact material.
