Exploring the Role of Antibacterial Nanoparticles Addition in Biodeterioration of PEO-treated Ti-base Alloys: A Mini-Review |Biomedgrid

Ti-base alloys possess a wide variety of attractive properties, including, but not limited to, good biocompatibility, excellent corrosion resistance, satisfactory mechanical characteristics and high specific strength, making them viable candidates for biomedical applications [1]. Nonetheless, the inappropriate bone bonding of these alloys and the subsequent accumulation of abrasive particles at the alloy/tissue interface lead to implant failure. Meanwhile, the biodeterioration of many Ti-alloys, like Ti6Al4V, would be accompanied by the release of hazardous metal ions akin to aluminum and vanadium into the surrounding tissue and body fluid, which in turn results in health problems, including allergy, toxicity and inflammation. Consequently, the necessity to apply protective coatings upon the surface of such an alloy is highly demanding [2].
