| Abstract Scope |
The key concern facing the biodegradable Mg-Ca implant is the fast corrosion in the human environment. The ability to adjust degradation rate of Mg-Ca alloys is critical for the effective development of the biodegradable orthopaedic implants. This study focuses on the microstructure and mechanical properties including the wear rate and hardness test. The wear mechanism of Mg-Ca Alloys with Mg-0.1 Ca, Mg-0.3 Ca and Mg-0.51 Ca was discussed. Dry Sliding tests were performed on Mg-Ca Alloys using a pin on disc configuration, Wear Rates were measured within a load of 2 to 15 Newton and a constant sliding velocity of 250 rpm. Worn Surfaces were examined using a Scanning Electron Spectrometry (SEM). Three Wear Mechanisms were observed namely Abrasion, Oxidation and Plastic deformation have been observed. |
