In addition to destroying materials, the products released during corrosion can cause adverse reactions in the human body. Corrosion testing of any material proposed for biomaterials should therefore be conducted in a model or controlled environment similar to that of the human body. In this work, the results obtained in the study of high nitrogen stainless steel (HNS) as a material for the fabrication of implants are presented and compared with the results for classical Cr-Ni stainless steel, in analogous environments and conditions. The tests were carried out in Ringer’s and Hartmann’s solutions, at specified concentrations, temperatures and pH values. A three-electrode glass cell was used under open air conditions. The following electrochemical methods were used: open circuit potential (OCP) – time measurement, cyclic potentiodynamic and potentiostatic polarizations. By means of light and scanning electron microscopy, surface changes were determined after exposing the steel specimens to the experimental media. The surface of the samples was also examined by EDX analysis to determine the nature of the corrosion products formed. From the results obtained, it was found that HNS-steel has higher resistance than Cr-Ni-steel in the model solutions studied.}, title={Comparison of Corrosion Behavior of Two Stainless Steels for Medical Applications}, type={Article}, URL={http://czasopisma.pan.pl/Content/133586/AMM-2024-4-49-Fachikova.pdf}, doi={10.24425/amm.2024.151439}, keywords={Biocompatibility, stainless steels, high nitrogen steels, corrosion, electrochemical method}, }
