Abstract

The present paper is the second part of a study of the laser metal surface hardening techniques using a 3 kW cw carbon dioxide laser. The laser alloying and laser cladding techniques are analyzed by experiment. The main results of both processes are given as a function of the more important parameters involved in them: the laser specific power, energy density, volumetric energy density, etc. Finally, the results of a wear resistance mechanical assay are included in order to compare the different surfaces obtained by all the used laser techniques, including in this paper and in the previous one.
