海水淡化是解决人类水资源缺乏的有效方法。被誉为“海洋金属”的钛及其合金在海水中具有优异的耐蚀性,是所有在天然水中最耐腐蚀的金属材料,且密度小,强度高,耐热性能好,是海水淡化装置用最具竞争力的材料。本文对海水淡化技术和钛及其合金在海水淡化产业的应用状况进行了概述,并对钛及其合金在海水淡化产业应用的前景进行了分析。 Desalination is an effective solution to the shortage of human water resources. Known as “marine metal ” titanium and its alloys have excellent corrosion resistance in seawater, all of the most corrosion-resistant metal materials in natural water, and the density, high strength, good heat resistance, is the sea water Desalination device with the most competitive materials. This paper summarizes the application of desalination technology and titanium and its alloys in seawater desalination industry and analyzes the prospect of application of titanium and its alloys in desalination industry.
