Abstract

Unmanned underwater vehicles are one of the indispensable tools for people to develop， utilize and explore the ocean， and have broad military application prospects.With the continuous progress and development of science and technology， unmanned underwater vehicles continue to break through their own limits of working depth.Due to the particularity and complexity of the marine environment， the requirements for its structural materials are becoming increasingly higher.In this work， based on the latest research progress at home and abroad， a comprehensive analysis was conducted on the corrosion factors of unmanned underwater vehicles structural materials in the marine environment，including seawater temperature， pH value， salinity， chloride ion concentration and dissolved oxygen content.Aiming at the corrosion types of unmanned underwater vehicles structural materials in the marine environment， the causes of corrosion of underwater vehicles structural materials in special working environments were explored.Besides， the anti-corrosion methods of unmanned underwater vehicle structural materials in marine environment were described， and the development of its future anti-corrosion technology was prospected.

Key words： unmanned underwater vehicles; structural materials; corrosion types; anti-corrosion coatings; cathodic protection
