由于钛具有优良的耐蚀性，使其维护成本降低，比强度高、燃料消耗减少，因此，近年来钛在船舶应用领域备受人们关注。现在已经在检查规范较宽松的渔船上开始用作结构材料，但在检查规范严格的客船和货船上，由于缺乏应用业绩、设计、制造及检查方法均未确立，所以为了制订规范 Due to the excellent corrosion resistance of titanium, the maintenance cost is reduced, the specific strength is high, and the fuel consumption is reduced. Therefore, titanium has drawn much attention in the field of marine applications in recent years. Now it has been used as a structural material on fishing vessels with more relaxed inspection norms. However, due to the lack of application performance, design, manufacture and inspection methods have not been established on passenger ships and cargo ships with strict inspection standards. Therefore, in order to formulate norms
