Abstract

The use of alloyed steels in industry to fabricate different parts and components has become increasingly common. This is due to their high resistance to oxidation and corrosion. In the vast majority of cases, the oxide layer has a protective role, generally against corrosion. However, for the fabrication of certain products, some of the manufacturing steps require the removal of these oxides, both as a pre-processing step and as a post-processing step, depending on the functional role of the respective component / product. The removal of this oxide layer can be determined by the requirements of the product appearance and/or the functional aspects of the product. The aim of this paper is to determine the optimal process parameters for removing these oxides by laser ablation, without causing structural and tribological changes of the material, regardless of it being a pre- or post-processing method..
