Surface modification on metallic biomaterials for biomedical applications

Metallic biomaterials such as magnesium (Mg) alloys are promising for implants due to their superior biocompatibility and mechanical properties, which closely resemble human bone, preventing stress shielding. Magnesium is an essential mineral involved in metabolism and enzyme support. However, Mg alloys corrode rapidly, releasing hydrogen gas and compromising mechanical stability before healing is complete, limiting their clinical use. Biomedical implants must also have sufficient fatigue strength and wear resistance to withstand daily activity. Enhancing Mg alloys' corrosion resistance, wear properties, and antibacterial features is crucial for their functionality. Surface modification, such as nanocomposite coatings with strong adhesion and bioactive properties, offers an effective solution. Additionally, the cell-substrate interface plays a key role in regulating cell response and function. The grain structure of Mg alloys, representing the atomic arrangement within the material, is a critical biophysical factor influencing cell adhesion and mechanical properties.

Key objectives and potential impact 

The main objective of this project is the development of surface modification/treatment technologies (such as nanocomposite coating, nano surface induced by severe plastic deformation) to improve the mechanical and biophysical properties of metallic biomaterials.
