金属生物医学材料和器件的腐蚀性能通常使用电化学技术进行评估。尽管涉及这些技术的测试标准已经发布，以解决某些形式的腐蚀，但一个关键问题是关于在体内使用植入式装置的结果的应用。本文综述了镍钛诺、316L/LVM不锈钢和Co-Cr合金，并就这些合金在模拟生理溶液中的一般腐蚀、局部腐蚀、电偶腐蚀和微动腐蚀试验结果的意义提供了一些看法。它还研究了可能导致体外和体内暴露之间腐蚀性能差异的因素，目的是为应用从试验中获得的电化学特性来预测体内腐蚀性能提供一些基本原理。©2018 Wiley期刊公司[J]中国生物医学工程学报，2016,31(1):1 - 4。
The corrosion performance of metallic biomedical materials and devices is commonly evaluated using electrochemical techniques. Although test standards involving such techniques have been released to address some forms of corrosion, a key issue is application of the results with regard to use of an implantable device in vivo. This review focuses on nitinol, 316L/LVM stainless steel, and Co-Cr alloys and is intended to provide some perspective on the significance of results from tests concerning general corrosion, localized corrosion, galvanic corrosion, and fretting corrosion of these alloys in simulated physiological solutions. It also examines the factors that could cause differences in the corrosion performance between in vitro and in vivo exposure, with the goal of providing some rationale for applying electrochemical characteristics obtained from the tests to predict the corrosion performance in vivo. © 2018 Wiley Periodicals, Inc.
