A comparison has been made of the electrochemical behaviour of investment cast coupons of a 20Cr, 25Ni, Ti stabilized stainless steel (in the nitrided and un-nitrided conditions) with a cobalt-chromium alloy in order to make a preliminary assessment from the point of view of corrosion of the nitrided material for dental and other biomedical applications. Electrochemical tests have been carried out in vitro in artificial saliva and in Ringer's solution, with some additional tests carried out in natural saliva. Both the potential-time behaviour and the magnitude of the breakdown potential on anodic polarization suggest that the protective properties of the passivating film are substantially improved in the case of the nitrided stainless steel alloy.
为了从牙科及其他生物医学应用中氮化材料的腐蚀角度进行初步评估，对一种20Cr、25Ni、Ti稳定化不锈钢（在氮化和未氮化条件下）的熔模铸造试样与一种钴铬合金的电化学行为进行了比较。已在人工唾液和林格氏溶液中进行了体外电化学测试，并在天然唾液中进行了一些额外测试。阳极极化时的电位-时间行为和击穿电位的大小均表明，对于氮化不锈钢合金而言，钝化膜的保护性能有了显著提高。
