摘要:

隨著生物醫(yī)用金屬材料的市場應(yīng)用快速增加，生物醫(yī)用鈦及鈦合金已成為人體植入物的主要原料，然而相比于不銹鋼及鈷基合金，常規(guī)鈦及鈦合金雖在生物醫(yī)用領(lǐng)域各方面性能都較為優(yōu)異，但作為植入物處于人體較為復(fù)雜的環(huán)境中時，其各方面性能還有待提高。因此，超細(xì)晶鈦及鈦合金的研發(fā)在醫(yī)用市場具有廣闊的前景。目前，市場上超細(xì)晶金屬材料的制備以劇烈塑性變形工藝為主，其中等通道轉(zhuǎn)角擠壓變形的制備方式較為成熟。對生物醫(yī)用超細(xì)晶鈦和鈦合金的類型及特點作了簡單的介紹，著重從等通道轉(zhuǎn)角擠壓變形方式制備的超細(xì)晶鈦及鈦合金在生物醫(yī)學(xué)上的耐蝕性、生物相容性、力學(xué)性能及疲勞性能等方面進行了簡述，對其在醫(yī)療市場的未來發(fā)展趨勢作出了展望，并總結(jié)了其未來發(fā)展待解決的問題。

Abstract:

With the rapid increase of biomedical metal materials in the market, biomedical titanium and titanium alloys have become the main raw materials for human implants. However, the performance of conventional titanium and titanium alloys compared with stainless steel and diamond-based alloys in various aspects in the medical field is excellent, but its performance as an implant in the more complex environment of the human body needs to be improved. Therefore, the research and development of ultrafine-grained titanium and titanium alloys have great practical significance and broad market prospects in the medical market. At present, the preparation of ultrafine-grained metal materials on the market is mainly based on the severe plastic deformation process, and the equal channel angular pressing deformation method is more mature. This article briefly introduces the types and characteristics of biomedical ultrafine-grain titanium and titanium alloys, focusing on the biomedical corrosion resistance, biocompatibility, mechanical property and fatigue performance of ultrafine-grained titanium and titanium alloys prepared from equal channel angular pressing deformation method. Meanwhile the future development trend of biomedical ultrafine-grain titanium and titanium alloy in the medical market, and the problems to be solved are introduced.
