| Resumo: | The use of AISI 316L stainless steel as a biomaterial for application in implants is already widespread
throughout the market due to its mechanical properties and low cost, however, some of its characteristics
hinder its biocompatibility with human tissue. Therefore, studies of coatings in order to improve these
characteristics have been carried out on a large scale. In this work, we sought to obtain a calcium
phosphate-based coating through electrolytic plasma oxidation (Plasma Electrolytic Oxidation – PEO)
using the potential difference in its two characteristics, both anodic and cathodic at different exposure
times. The morphological characterization and the study of the samples took place through X-Ray
Diffraction (XRD) to determine if there was really deposition of hydroxyapatite, a ceramic material, on
the steel surface and also by Scanning Electron Microscopy (SEM), both topographical and side, to
evaluate the amount of material deposited and thickness of the coating acquired. As a result, it was
possible to observe a better efficiency in the deposition of material when the pole used in the PEO was the
anodic one. |
