Localised corrosion behaviour of biomedical implant materials using electrochemical potentiokinetic reactivation and critical pitting potential methods
Source abstract
Abstract
In this study, localised corrosion properties of the biomedical grade Ti–Nb–Cu alloy and AISI 316 austenitic stainless steel specimens were investigated. Ti–Nb–Cu alloy specimens were produced by powder metallurgy method. Nb was used for beta-phase Ti stabiliser. Beta-Ti phase has low Young’s modulus close to bone, higher wear resistance and biocompatibility. Cu was added to enhance sinterability of the Ti–Nb–Cu alloy; in addition, Cu is antibacterial. The AISI 316 austenitic stainless steel alloy was investigated as wrought (fully dense) specimens. Localised corrosion properties of the Ti–Nb–Cu and AISI 316 stainless steel alloys were examined by electrochemical potentiokinetic reactivation, critical pitting potential and Tsujikawa–Hisamatsu electrochemical tests in Hank’s simulated body fluid solution. Effect of the Cu content of the Ti–Nb–Cu alloys and pH level of the simulated body fluid on the corrosion behaviour of the specimens was studied.
