Abstract

Surface enhancement of titanium based alloys is made through different methods and improves the biofunctionalization of alloy and the deposition capacity of nonmetallic thin layers (hydroxyapatite or polymers). Thin coatings deposition on metallic substrates represents an improvement method of material properties, especially those used in the medical field as in-contact body applications. Few chemical engraving methods based on acid solution attack of the surface were used to prepare a Ti-based alloy wire surface. The surface area activation was calculated and chemical and microstructure analyses were performed using X-ray energy dispersive analyze and scanning electrons microscopy (2 and 3D) to establish the applied solution effects..
