Abstract

Titanium alloys, especially Ti6Al4V, are widely used in in-body implants due to their superior mechanical properties, corrosion resistance and biocompatibility. However, due to their higher modulus of elasticity than bone, they do not bond well with the bone structure, leading to loosening. In addition, they contain the elements Al and V, both of which are dangerous when released into the body. Therefore, these alloys are subjected to a number of surface treatments to improve their surface properties. In this study, Ti6Al4V alloys were produced by selective laser melting in dimensions of 10x10x2 mm3 and then surface treated. The alloy surfaces were first anodized and then coated with 45S5 bioglass powder. After all surface processes, structural analyzes were performed and the effectiveness of the coating was examined. The untreated and coated samples were subjected to corrosion tests by cyclic polarization method and their corrosion behaviors were investigated.
