| Popis: | The salient features of cost-effectiveness, ease of fabrication, and excellent mechanical stability offer the importance of surgical grade 316L SS in bone replacement surgery. Despite the salient features, corrosion during in vivo implantation restricts the application of 316L SS. In this context, bio-ceramic coatings on metallic implants are highly preferred as it protects the underlying metal from corrosion and also accomplish good interfacial bonding between the metal substrate and the defective bone. Here in, a novel Sr/Mg-substituted 58S bioglass coating on 316L SS is developed. Sol–gel technique is employed for the synthesis of bioglass powders and their subsequent coatings on 316L SS are performed through electrophoretic deposition. The physiochemical and electrochemical characterization of the coatings were evaluated through suitable analytical techniques. The important electrochemical corrosion parameters such as corrosion current density (Icorr) and corrosion potential (Ecorr) were investigated in simulated body fluid conditions. The results envisaged the significant electrochemical shift towards the noble direction for the coated specimens than the uncoated substrate. The stability of the coatings is confirmed from the high polarization resistance and low capacitance values. |
