In recent years, magnesium and magnesium alloys have received much attention as a new biomaterial in orthopaedic applications due to their biodegradability, biocompatibility, and their mechanical properties that are similar to natural bone tissue. The most common problem associated with magnesium as a biomaterial is low corrosion resistance in physiological solutions. This decreases the mechanical integrity of the implants in the early stages of healing and has a negative impact on the overall biocompatibility. The main goal of this study was to create a multi-layered coating consisting of a silica sol-gel under-layer to protect the substrate from corrosion in body fluids and a mesoporous silica top-layer to enhance the bioactivity of the coated implant material.
The results indicate that the deposited multi-layered coating enhances both the bioactivity and the corrosion resistance of the material.
