Resumo
This chapter evaluated the influence of laser texturing process on the tribological behavior
of the ISO 5832-1 austenitic stainless steel (SS). The friction coefficient and wear were
determined using ball-cratering wear tests. The laser texturing process was carried
out with a nanosecond optical fiber ytterbium laser at four different pulse frequencies.
Cytotoxicity tests were carried out to determine if laser texturing affects the biomaterial
biocompatibility. For comparison reasons, pristine surfaces were also evaluated. The
results indicated that the wear volume and friction coefficient were reduced after laser
texturing. The samples were considered noncytotoxic according to the biocompatibility
tests as the laser texturing process did not decrease cell’s viability.
