应用一种新的单片电极系统对几种骨科植入物用合金的阳极极化进行了活体和体外测量。每次实验结束后，用体视显微镜仔细观察被测表面。这证实了凹坑的形成，并排除了其他突然增加的阳极电流的可能性，如缝隙腐蚀和有机物的氧化或还原。结果重现性好。虽然在两种条件下得到的结果有一定差异，但合金的耐蚀性顺序是一致的。
A new system of single piece electrodes was applied toIn vivoandin vitromeasurements of anodic polarization of several alloys used in orthopaedic implants. The tested surface was scrutinized with a stereomicroscope after each experiment. This confirmed pit formation and excluded the possibility of other sudden increase of anodic current such as crevice corrosion and oxidation or reduction of organic substances. The results were reproducible. Although there were certain differences between the results obtained in the two conditions, the order of corrosion resistances of alloys was consistent.
