钛在海洋工程应用的最新进展

New developments of titanium in ocean engineering application

海洋工程用材料,除要求耐海洋腐蚀环境外,还要求高性能、高功能、安全可靠性、实用性等。钛的比强度高,耐海水腐蚀和海洋气氛腐蚀,又有良好的抗腐蚀疲劳性能,可以很好地满足人们在海洋工程方面应用的要求。本文对钛在海洋工程,包括海水淡化、舰船、海洋油气开发、沿海发电站、海港建筑和海洋设施等领域应用的现状和最新进展进行了综述,并对未来发展前景进行了展望。

Materials that used in ocean engineering require not only corrosion-resistant in marine environment, but also high performance, high functionality, security, reliability and practicability. Titanium has high specific strength, resistant seawater and ocean atmosphere corrosion. It also has good resistant corrosion fatigue property. It can satisfy the requirements in ocean engineering application. The status and new developments of titanium in ocean engineering application, including desalination of seawater, ships, ocean oil and gas exploiting, coastal power plant, seaport construction and marine facilities are summarized in the paper. The developments in the future are also forecasted.
