Abstract

Laser cladding tests have been performed using a high power CO₂, laser realized by CISE. In this process a high power beam is focussed on the surface of the substrate to be cladded. The beam produces a surface melting while a powder flow, carried by an inert gas, is blown into the melt pool. The advantages of the laser cladding compared to the conventional cladding processes are the following: - effective metallurgical bonding between the cladded layer and the substrate with a very low heat transferred to the workpiece; - high hardness of the cladded layer with a low dilution without cracks or porosities; - less pre and post-process operations. Example of laser cladding tests of cobalt base powder on stainless austenitic and martensitic steels and on construction steels are reported.
