In-depth Assessment of New Ti-Mo based Alloys for Medical Application. 

Abstract.

Population health and all materials used in medical application has always been an intense concern for researchers. Biomaterials play a role important in medical fields. For the functionality of a material for use in medical applications, three important factors are taken into account: biocompatibility, mechanical properties and corrosion resistance. In recent years, researchers have been trying to improve titanium alloys with different alloying elements to replace current alloys. In this context, we have developed two new TiMoSi and TiMoZrTa alloy systems, with original recipes, whose properties are much improved compared to the current biomaterials. These systems were obtained in a vacuum arc melting furnace (VAR) with argon atmosphere. The elaborated alloys have elements with a high biocompatibility with the human tissue having specific mechanical/ chemical properties as close to those of the organ they are prosthetizing. These alloys were evaluated in solutions/fluids similar to the human body. Results revealed a good behavior which does not influence the human body and can be considered for future applications in medical field.
