我国海洋工程用钛合金发展现状及展望

Development Status and Prospect on Application of Titanium Alloy in Ocean Engineering

摘要: 钛及钛合金以其优异的性能特点在海洋工程方面有广阔的应用前景，我国海洋用钛合金已有较为完善的合金体系，并有一定的应用。但目前由于应用的性能数据支撑不充足，海洋工程结构件建造规则还不完善，加工设备能力不够、产品规格小以及材料生产成本高等诸多原因，海洋用钛合金尚存在产业化水平低、应用不足的问题。随着国家对海洋建设的重视，钛合金工程化应用程度的加快以及材料成本的降低，未来海洋用钛将有非常大的发展空间。

Abstract: Titanium alloy has broad application prospects in ocean engineering due to its superior perfor-mance. In China, the titanium alloy used in ocean engineering has a relatively perfect system and has been applied partly. Because of many reasons, such as, insufficient application performance data of titanium alloy, incomplete construction rules of ocean engineering component, inadequate plant capacity for producing titanium alloy, small product specifications and high production cost , the marine titanium alloy used in ocean engineering has been limited. With the emphasis on ocean construction, the acceleration of application of titanium alloy in ocean engineering and the reduc-tion of production cost of titanium alloy, the marine titanium will have broader development space in the future.
