沿海两栖车辆腐蚀现状及腐蚀综合控制技术

The Corrosion Status of Amphibious Vehicles along the Coast and Integrated Corrosion Control Technology

针对两栖车辆在海洋环境下的使用情况,全面系统地介绍了两栖车辆在海洋环境下的腐蚀情况,并针对腐蚀问题和规律,提出两栖车辆腐蚀综合控制的理论及防腐设计原则。重点介绍了两栖车辆Al-Zn-In-Mg-Ga-Mn六元牺牲阳极材料、陶瓷型耐磨蚀涂层、复合防腐涂覆层、异种金属电位匹配、高分子密封防腐等专项腐蚀防护技术,提出树立全系统和全过程腐蚀综合控制的思想,制定以预防、控制和治理为主要内容的工艺规程,构建腐蚀控制维修保障的配套技术手段,从顶层完善工腐蚀控制理论体系。

The corrosion status of amphibious vehicles is comprehensively introduced for the usage of amphibious vehicle in marine environment. The integrated corrosion control theories and anti-corrosion de- sign principles of amphibious vehicles are proposed according to corrosion problems and laws. This paper highlights A1-Zn-In-Mg-Ga-Mn sacrificial anode materials for amphibious vehicle, abrasion resistant ce- ramic coating, composite anticorrosion coating technology, potential matching technology of dissimilar metals, polymer sealing anti-corrosion technology, and special corrosion protection technology. The whole process of system-wide corrosion control ideas is set up, and a technological procedure of prevention, control and governance is developed. The supporting technology for corrosion control and maintenance support is established, and the theoretical system of corrosion control is improved from the top-level.
