Resumo
The laser techniques usage on the biomaterial’s field includes welding, engraving, cutting
and texturing. The present study evaluated the influence of laser texturing process on the
tribological behavior of AISI 316L austenitic stainless steel (SS) on the friction coefficient
and wear volume in ball-cratering wear tests. The laser texturing process was carried out
with a nanosecond optical fiber ytterbium laser at four different pulse frequencies.
Advanced selective laser melting (SLM) techniques allow the production of pieces with the
most varied sizes, shapes and complex geometries. For comparison reasons, pristine
surfaces were also evaluated. The sample’s surfaces finishing was analyzed by laser
confocal microscopy. The wear tests were carried out during 10 min, solid spheres of 52-100
chrome steel, with 2 mm in diameter, were used as counter-bodies. The results indicated
that the tribological behavior is influenced by the laser additive manufacturing (AM) process
parameters used for this biomaterial, and the wear rate is dependent of the normal force
and the roughness of each specimen.
