Abstract

A technology has been developed for surfacing copper molds by the method of friction with stirring (STM), which allows surfacing copper on molds with subsequent application of a wear-resistant metal coating. The possibility of surfacing nickel on a copper plate by friction with stirring using a tool made of tungsten-bearing materials and cubic boron nitride is shown. The temperatures and forces acting during friction stir surfacing of copper and nickel on copper plates of molds have been determined.
