Development and Application of Biomedical

Original Title: Development and Application of Medical Titanium and Titanium Alloys for Surgical Implants 1. Introduction Titanium and its alloys used as surgical implants have many advantages, such as low density, high strength, good toughness, good biocompatibility, non-toxic, low elastic modulus, good corrosion resistance, low X-ray absorptionnal correction rods, intramedullary nails, artificial heart valves, dental implants, skull and other products. The world's population is nearly 6.5 billion, and the global aging problem is very serious. According to the data of F & S Company, the compound growth rate of the global orthopaedic implant device market in the past five years is about 10.4%, which is expected to reach 27.7 billion US dollars by 2015, while the Chinese orthopaedic implant device market will grow to 16.6 billion US dollawas developed by Germany. Compared with Ti-6Al-4V alloy, vanadium is replaced by cheap and non-toxic iron element. Ti-5Al-2. 5Fe is a medium-strength material, which is equivalent to Ti-6Al-4V in terms of mechanical property,titanium tubing price, toughness and fatigue strength. These two alloys have also been developed in China. Ti-6Al-7Nb and Ti-5Al-2.5Fe alloys have been developed by the joint efforts of Baotai Group Co., Ltd., Beijing Central Research Institute for Nonferrous Metals, Hebei Medical University, Shandong Wendeng Orthoe compatible with human soft and hard tissues and biomechanics, the new β-titanium alloy, has become the focus of biomedical metal materials research. A series of new type β titanium alloys were developed by adding non-toxic elements such as Nb, Ta, Zr,titanium filler rod, Mo and Sn. 2.3 Ti-Ni alloy. Ti-Ni shape memory alloy is a new type of functional material.  At the same time, the rough surface geometry of porous titanium alloy can promote the anodic oxidation, hydrothermal treatment and heat treatment. The prepared gradient coating has complete crystal form, titanium bar grade 5 ,titanium seamless tube, and the surface of the gradient coating has high capability of inducing a bone hydroxyapatite layer to form surface treatment and technological level of titanium alloy implants. The implants produced in China are difficult to meet the market demand, and most of the high-end implants need to be imported from abroad,titanium sheet grade 5, which has brought unprecedented opportunities and challenges to medical material research units, material manufacturers, medical research institutions and clinical medical experts in China. These units should strengthen cooperation and work hard to achieve the localization of high-end implants for the benefit of the people. To promote the healthy and stable development of China's medical titanium alloy industry. Return to Sohu to see more Responsible Editor:. yunchtitanium.com
