ABSTRACT
A metallic biomaterial is broadly hired inside the manufacturing of health-related products for hard tissue substitute, including pacemaker cases and screws to assist patients when their body parts are damaged. The basic information of three main categories of metallic implant biomaterials; stainless steel-, cobalt- and titanium (Ti)-based alloys has been incorporated in this chapter. In addition to mechanical performance, the other essential requirements that needed to be posted by these metallic biomaterials are also explained. Various advantages of using these metallic biomaterials as an implant and their current applications are also reviewed. The main issue during implantation of a biomaterial (i.e., a Ti implant) and its alloys is inflammatory response in surrounding tissues, eventually leading to implant failure, even with biomaterials exhibiting excellent properties. Some of the recent notable physical and chemical surface-treatment approaches and the obtained results thereof contributing to biomedical field have also been covered in this chapter.
