Titanium electrode with human epithelial tissue, connective tissue, bone has the good affinity, excellent mechanical properties but also its advantages in medical alloy. And small density, light quality, good corrosion resistance, wear with comfort, therefore, titanium electrode as denture (plant) to receive widespread favour. In addition, the titanium electrode denture through surface treatment after ti6al4v eli beautiful performance increase, can satisfy the public demand for beauty, give a person with visual enjoyment. With the rapid development of national economy, medical titanium electrode alloy because of its excellent performance, in the field of health care demand is increasing. As a biological metal materials with excellent properties of titanium electrode and its alloy has good prospects for application in medical field. However, compared with the developed countries at present, the research and development and application of titanium electrode alloys also has certain gap, such as: the titanium electrode alloy has high elastic modulus and poor surface activity, lack of poor wear resistance and corrosion resistance, will directly affect the biocompatibility of material. Therefore, in order to develop better comprehensive properties of new type of titanium alloy electrode, our country should increase the intensity of materials research and development, pay attention to innovation, the titanium plate gr7 development of low elastic modulus, high wear resistance, corrosion resistance and excellent biocompatibility of biomedical titanium electrode alloy material.
In the process of the design of the ti6al4v titanium alloy electrode, d electronic design theory is the basic method for alloy design. The basic idea is: based on Ti and add elements of the electron orbital parameters calculation, get the corresponding value and Bo, Md, in turn, elastic modulus and tensile strength of alloy and related parameters were analyzed. Experimental results show that the Md value lower to stable phase, Bo high value to improve the solid solution strengthening effect. In the interface can be used for beta type titanium electrode alloy design, should control the Md value 2.35 ~ 2.45, and Bo value is between 2.75 ~ 2.85. The thermal stability of the beta type titanium electrode alloy sliding deformation happens in plastic processing, while type medium stable beta titanium electrode alloy sliding, martensite can occur or twin deformation. Thus by controlling different alloy microstructure structure can make the material performance was improved in a wide range. Medical titanium electrode alloy as a new type of alloy, is also a titanium round bar kind of carrier material, is widely applied to the limb implants, alternative sexual materials, dental, medical apparatus and instruments, etc. Titanium titanium electrode and electrode alloy are: good corrosion resistance, high specific strength, low modulus of elasticity, fatigue resistance, good biocompatibility, etc. Including biocompatibility this characteristic makes it has unique advantages compared with other metals, thus titanium sheet grade 5 gain favor in the medical field, but because of its resistance to wear and process performance is not high, is committed to the further improvement has been conducted.
