Feasibility study of wide band laser surface treatment

Abstract

In the field of materials processing, the laser techniques employed for surface modification have contributed greatly to the development of materials with specific features. However, despite the advantages of laser surface treatment, its application is limited because the process is slower than other techniques. This paper presents a feasibility study of wide band laser treatment, a method that, by enlarging the scanning width, increases the efficiency in comparison to several tracks of conventional laser surface treatment. Experimental tests have shown that wide band laser treatments with this experimental system can achieve processing rates 10 times higher than conventional devices. © 2013 The Authors.
