Increased use of titanium alloys as biomaterials is occurring due to their superior biocompatibility and high corrosion resistance in the human body. Ti-6Al-7Nb was investigated compared with Ti-6Al-4V and two surface treatments were applied for increasing the bioactivity of the alloy. The results were interpreted from electrochemical and statistical point of view. It can be concluded that the alloy Ti-6Al-7Nb is a real alternative to the well-known Ti-6Al-4V alloy, which has been used for decades as an implant material and the obtained results are important for the safe long-term in vivo application of the Ti-6Al-7Nb alloy since niobium has the characteristics of an immunologically inert metal.
