Abstract
The aim of this paper is to evaluate the influence of the working parameters in the micro-machining process of stainless steel 316L by means of 355 nm Nd:YVO4 nanosecond laser. Our target is the surface modification of metallic bioimplants to favour osseointegration. Well organized structures, like a matrix of drilling holes or a pattern of grooves, were created in the metallic surface by means of different treatments in which both laser parameters and irradiation schemes were varied. Processed metal surfaces were characterized by confocal microscopy and scanning electron microscopy SEM. The results allowed us to establish the most adequate processing parameters to generate textured micro-features in a range suitable for biomedical applications
