Abstract Scope |
The in-vivo degradation rates of a range of low alloy content magnesium alloys suitable for the manufacture of medical implant devices has been explored and compared to the in-vivo corrosion rates of the commercial WE43 alloy. The degradation behaviour of the alloys was carefully measured using in-vivo weight loss measurements and the biocompatibility of each of the alloys has been evaluated using detailed histological analysis. Differences in the corrosion behaviour are explained in terms of alloy microstructure. Degradation behaviour was found to be associated with the development of hydrogen gas in the implanted specimens. The evolution of hydrogen with time and related histological effects were also examined in this study using CT scan information and related histological evaluation. |
