【摘要】：正钛及钛合金具有高的生物相容性、低密度、良好的力学性能以及优良的抗腐蚀能力,是生物医用领域的首选金属。钛基合金在牙科领域已有广泛应用,它们的焊接能力也成为该领域的热议主题。当前钛基合金牙种植体的焊接问题主要是热影响区的形成以及钛在高温下易与氧、氢、氮发生反应,这些都会对种植体的长期使用造成影响。
[Abstract]:Titanium and titanium alloys have high biocompatibility, low density, good mechanical properties and excellent corrosion resistance.Titanium-based alloys have been widely used in the field of dentistry, and their weldability has become a hot topic in this field.At present, the welding problems of titanium alloy dental implants are mainly caused by the formation of heat-affected zone and the reaction of titanium with oxygen, hydrogen and nitrogen at high temperature, which will affect the long-term use of the implants.
