LASER PROCESSING OF METAL-CERAMIC COMPOSITE MULTILAYERS

Abstract
Particulate metal-ceramic composite layers were formed using a CO2-Laser. Opposed to other methods hard phases (TiC, TiN, NbC) were embedded in a steel surface by liquid metal penetration into a predeposited layer of fine hard particle powders. The structure of surfaces processed by this method differs from those of conventionally treated surfaces. Hard phases incorporated in the steel matrix variied gradually in type, size and volume fraction from the surface to the substrate. Produced layers were in the range between 30 and 150 µm and free of pores and cracks.
