Tantalum Metal - Human Body ''pro-metal''

Metallic materials are widely used in clinical medicine due to their high suitability for mechanical properties and fatigue resistance, and are suitable for the implantation of bearing components. A variety of metal materials such as stainless steel, titanium-based and cobalt-based alloys have been widely used in clinical practice and have achieved certain therapeutic effects.

However, the complex human environment may lead to corrosion of materials and release of toxic substances, which greatly reduces the biocompatibility of metallic materials. In addition, the elastic modulus of some metal materials is too different from that of human skeletal tissue, which is not conducive to the growth and remodeling of new bone, and easily leads to secondary fractures. These unfavorable conditions limit the application of metallic materials as biomedical materials.
