Comparison study of Sn and Bi addition on microstructure and bio-degradation rate of as-cast Mg-4wt% Zn alloy without and with Ca-P coating

Mg-based implants, have useful properties such as biocompatibility, low density and elastic modulus close to natural bones eliminating of additional surgery for implant removal. On the other hand, they degrade rapidly in the early stage after implantation. This leads to some problems such as fast de...
