摘要

Titanium alloy (Ti-6Al-7Nb) used for orthopaedic applications was nitrided using a conventional dc plasma technique. Load-dependent microhardness measurements exhibit a hardness of 2087 H_v at 25 g load for the alloy nitrided at 900℃ for 8 h. Cyclic polarization measurement in Hanks solution show maximum corrosion rate and minimum area of repassivation for the alloy nitrided for 8 h at 900℃. Electrochemical impedance measurements show an increase in charge transfer resistance and decrease in double layer capacitance when compared to untreated alloy.
