Resumo
Marking is one of the last steps of manufacturing
an implantable biomaterial. The marks on its surface
constitute a permanent set of information in order to provide
identification and traceability of the biomedical device. These
markings become stress concentrators and regions with
probability for the occurrence of failures that can lead to
fracture; besides damaging the passive layer, naturally formed
on stainless steels surfaces, favoring the beginning of several
forms of degradation. This work presents the effect of two
metal implant marking techniques on the corrosion resistance
of ISO 5832-1 austenitic stainless steel, one of the most used
surgical biomaterials used in Brazil. Engraving was carried
out with mechanical and laser beam marking techniques were
prepared. The electrochemical behavior was characterized by
cyclic potentiodynamic polarization curves and indicate that
the laser marking technique is the one that most affects the
passive layer of the material when compared to the mechanical
engraving.
