Abstract

Abstract : This research assessed the corrosion behaviour of Ti35Zr28Nb compared to that of commercial purity Ti (CP Ti) Grade 2 under crevice‐corrosion conditions in: (i) Hanks' solution at 37 °C and (ii) 3.5 wt% NaCl solution at 95 °C. Both Ti35Zr28Nb and CP Ti showed low corrosion rates. There was no evidence of crevice corrosion indicating that both CP Ti and the Ti alloy were not sensitive to crevice corrosion under the conditions studied. Abstract : This work showed that there was no corrosion and no crevice corrosion for Ti35Zr28Nb and CP Ti Grade 2 under crevice‐corrosion conditions in Hanks' solution at 37 °C, and in 3.5 wt.% NaCl solution at 95 °C. Thus Ti35Zr28Nb is a potential material for biomedical applications. Illustrated is the Ti35Zr28Nb crevice‐corrosion assembly.
