国内外船用钛合金及其应用
发布时间：2019-07-18 05:58
【摘要】：钛合金因其良好的耐蚀性、可焊性以及高比强度等优点在舰船和海洋工程中得到广泛应用。船用钛合金的设计应遵从Al当量和Mo当量匹配的原则,以保证其具有良好的抗应力腐蚀性能和焊接性能。俄罗斯、美国、中国相继建立了自己的船用钛合金体系,并在船上管路系统、管路配套体系、结构件、推进器和深潜器中广泛应用。针对船用钛合金在使用过程中出现的缝隙腐蚀、电偶腐蚀和大型结构件焊接问题,提出了相应的保护措施及解决方法。此外,针对中国船用钛合金在应用中存在的不足,指出了中国船用钛合金深入研究和发展的方向。
[Abstract]:Titanium alloy has been widely used in ship and marine engineering because of its good corrosion resistance, weldability and high specific strength. The design of marine titanium alloy should follow the principle of matching Al equivalent and Mo equivalent to ensure its good stress corrosion resistance and welding performance. Russia, the United States and China have established their own marine titanium alloy system, and are widely used in ship pipeline system, pipeline matching system, structure, thruster and deep submersible. In order to solve the problems of crevice corrosion, galvanic corrosion and welding of large structural parts in the course of use of marine titanium alloy, the corresponding protective measures and solutions are put forward. In addition, in view of the shortcomings existing in the application of marine titanium alloys in China, the direction of further research and development of marine titanium alloys in China is pointed out.
