研究了低比例后过渡金属（LTM）玻璃在0.6M NaCl中的耐腐蚀性和疲劳性能，并与传统的Vitreloy玻璃和其他晶体合金进行了比较。由于它们能够形成均匀的钝化膜，低LTM玻璃的腐蚀速率比其他合金低一个数量级。溶液中的疲劳比大大低于所考虑的结晶合金，并且类似于传统的Vitreloy玻璃，其由于溶液中有限的再钝化而在低应力下失效。
Corrosion resistance and fatigue performance of Vitreloy glasses with low fractions of late transition metals (LTMs) in 0.6M NaCl are investigated and compared to a traditional Vitreloy glass and other crystalline alloys. Owing to their ability to form uniform passive films, low LTM Vitreloy glasses exhibit corrosion rates that are an order of magnitude lower than those of other alloys considered. The fatigue ratios in solution are substantially lower than crystalline alloys considered and similar to traditional Vitreloy glasses, which fail at low stresses due to limited repassivation in solution.
