ABSTRACT:
A method for providing a metal substrate with an impact resistant surface is disclosed. The surface of the substrate is exposed to high intensity laser radiation to melt a spot of the surface. Particles of a material such as WC are injected into the melt.
In order to enhance the percentage of particles in the surface, thus increasing the wear resistance, there is a forced reflection of stray particles back toward the melted spot.
Further a fixture for holding the substrate, comprising the essential reflection surfaces for achieving the desired back reflection is described as well as a device for carrying out the method.
