Abstract

The paper is a new approach of Ti-6Al-7Nb bioalloy biocompatibility improvement by surface treatment which ensure corrosion resistance and which could be a base for biological reactions leading to improvements in the tissue bond with the implant. The roughness evaluation was examined using atomic force microscopy (AFM) in contact mode. Corrosion resistance tests were carried out by potentiodynamic curves and electrochemical impedance spectroscopy (EIS) in Hank's Balanced Salt Solution (HBSS) with pH values characterized for neutral, inflammatory and stagnation state. The thermal treatments guarantee a high value of roughness and high corrosion resistance.
