Corrosion Resistance of Porous 316L Implant Steel

Abstract:

Article Preview

Porous metallic alloys are reported as the prospective biomaterials for restorative medicine due to their unmatched features guaranteeing fixation of prosthesis. Numbers of research are focused on functional properties of porous materials. Especially corrosion behavior seems to differ from the analogue bulk materials. The aim of presented work was to study corrosion resistance of sintered porous implant steel 316L. Samples with porosity in range of 26-40% were fabricated by means of the PM method. Corrosion tests were carried by using an automatic polarization unit Atlas-Solich98 in 0.9% NaCl water solution. The experiments conducted confirm that porous 316 stainless steel possesses a distinct passivation range. The obtained results showed the effect of pore morphology on corrosion resistance of sinters.
