Abstract

A wear-resistant surface is formed on a component formed of an AlSi alloy by using a thermal spraying or a laser beam treatment. A thermally conductive device is brought into a thermally conductive contact with the component so that the thermally conductive device touches the component during the step of forming the wear-resistant surface. The thermally conductive device is actively cooled.
