Effects of Ti6Al4V mechanical and thermal surface modification on the adhesion of a chitosan-bioactive glass coating

Abstract Biomedical implants interact with human tissues introducing significant perturbation into the body. Implant surfaces can be then functionalized enabling better biocompatibility. At same time, additional use of a coating provides further functions such as corrosion protection, osteointegration, and drug delivery. In this context, composite made chitosan bioactive glass nanoparticles has been used for Ti6Al4V alloy samples processed beforehand using different processes, i.e., polishing, milling, grit blasting, electrical discharge machining. Experiments have carried out to correlate substrate surface conditions effectiveness in terms scratch resistance final aim obtain suitable guidelines improve substrate-coating performances. Graphical
