【摘要】:骨科植入物的生物摩擦腐蝕耦合行為對人工假體使用壽命有重要影響.本文作者概述了生物摩擦腐蝕耦合行為研究的試驗(yàn)方案和主要分類,其中按照摩擦方式不同,可將其分為磨粒磨損腐蝕、微動腐蝕、滑動(摩擦)腐蝕、模擬器仿真(摩擦)腐蝕等類型,分析了影響該行為的主要因素,包括摩擦、電化學(xué)、材料和溶液因素等.通過調(diào)研國內(nèi)外文獻(xiàn),綜述了鈦合金、鈷鉻鉬合金和不銹鋼三種主要金屬材料在微動腐蝕、滑動摩擦腐蝕和模擬器摩擦腐蝕三類損傷模式下的研究現(xiàn)狀.接著介紹了鈍化膜去除、磨屑顆粒產(chǎn)生和金屬離子釋放過程,以及摩擦腐蝕耦合損傷機(jī)理.最后總結(jié)未來應(yīng)在假體真實(shí)工作環(huán)境模擬和再現(xiàn)、有機(jī)物(如白蛋白)等人體體液中特有物質(zhì)對植入物耦合行為影響和其他假體如人工椎間盤生物摩擦腐蝕等三個方面開展深入研究.
[Abstract]:The biotribological corrosion coupling behavior of orthopedic implants has an important effect on the life of artificial prosthesis. In this paper, the authors summarize the experimental schemes and main classification of the coupling behavior of biological friction corrosion. According to the different friction modes, they can be divided into abrasive wear corrosion, fretting corrosion, sliding (friction) corrosion. The simulator simulates the corrosion (friction) and analyzes the main factors affecting the behavior, such as friction, electrochemistry, material and solution, etc. The research status of titanium alloy, cobalt-chromium-molybdenum alloy and stainless steel in fretting corrosion, sliding friction corrosion and simulator tribological corrosion is reviewed. Then the passivating film removal, debris generation and metal ion release are introduced, as well as the coupled damage mechanism of friction corrosion. Finally, we conclude that the real working environment of prosthesis should be simulated and reproduced in the future. The effects of organic compounds (such as albumin) on implant coupling behavior and other prostheses such as artificial disc biotribological corrosion were deeply studied.
