Abstract
An electrical contact of the type having a working surface and comprising a ductile metal and weld inhibiting material includes a wetting agent present in an amount sufficient to reduce the surface energy between said contact surface and the liquid phase of the ductile metal. Improved wettability of the surface results in reduced arc erosion due to the spattering loss of ductile metal. Also, described is a method for selecting and testing proposed additives.
