摘要:: 航母作为人类有史以来最大的军事装备，是一项复杂的巨系统工程，使用的材料种类繁多，工作环境复杂。本文针对航母使用的苛刻环境条件，介绍了航母用材的通用选材原则，并且对船体结构材料、管路及附件材料、非金属材料的特殊选材要求分别进行了阐述。本文介绍了航母用材的腐蚀特点，一是腐蚀环境多样，防护要求高，防腐设计难度大；二是系统组成复杂，设备数量多，腐蚀故障影响大；三是舱室结构复杂，施工空间小，防腐修理难度大。针对腐蚀特点提出了航母用材的腐蚀控制需求，从腐蚀控制技术体系、腐蚀控制手段、材料防腐蚀性能三个方面阐述了航母用材的不足和差距，并针对性地提出了航母用材腐蚀控制的建议和对策。

Abstract:: As the greatest military platform in human history，aircraft carrier is a complicated giant system with a great variety of materials and complex operating environment. This paper presents the general principles in material selection for aircraft carrier operated in severe conditions, and elaborates on the special material requirements on the hull construction, the pipeline and accessories as well as nonmetal materials. The article introduces the characteristics of material corrosion on aircraft carrier. The First characteristic comes from the various corrosion environment，the highly standard protection requirements and the difficulty in corrosion design. The second one comes from the complication in system composition, the great amount of equipment and powerful influence on corrosion malfunction. The last one comes from the intricate cabin structures, the short of construction space and the difficulty in anticorrosion. Based on the corrosion characteristics of aircraft carrier materials, the paper expresses the control requirements of corrosion and elaborates on deficiency in selecting aircraft carrier’s materials based on investigation in corrosion control management, methods of corrosion control and capability of anticorrosion materials. And a series of pertinent advises and countermeasures in corrosion control has been provided.
