1957年Downs博士首先在矫形外科领域中应用了钛。现在已研制成常用的T318合金(即Ti4V6AL,内含钒和铝合金元素)。利用热等静压和冷加工等工艺可以大大提高它的性能并制成高强度部件。需要制成有轮廓的或将承受反向弯曲的植入物,可采用纯钛。一种金属若要在有化学腐蚀性的温暖的体内良好地工作,最重要的是其表面不活泼。 In 1957, Dr. Downs first applied titanium in the field of orthopedics. Now developed into common T318 alloy (ie Ti4V6AL, containing vanadium and aluminum alloy elements). Utilizing processes such as hot isostatic pressing and cold working can greatly improve its performance and make high-strength parts. Implants that need to be contoured or will be subjected to reverse bending may be made of pure titanium. A metal that works well in a chemically aggressive and warm body is most importantly its surface is not active.
