摘　　要：为满足轻量化需求,军用车辆逐步加大了铝合金等轻量化材料的使用。并且海陆两栖环境条件恶劣,其中盐分、湿度均较高。这对重防腐工艺设计、管理等方面提出了全新的挑战。以5A06、7075等多种铝合金材料构件为研究对象,分别采用阳极氧化处理、硬质阳极氧化处理和打毛处理,然后施涂氟碳体系涂料,并对涂料的配套性、重防腐性能进行了分析和研究。经过多项室内模拟加速性试验及对试验数据的对比、分析,考验了各项重防腐方案的环境适应性,筛选出了最适合铝合金构件的重防腐工艺方案。To meet the lightweight needs,military vehicles have gradually increased the use of lightweight materials such as aluminium alloy.And the amphibious environment conditions are harsh,in which the salt and humidity are high.This presents a new challenge to the design and management of heavy-duty anticorrosion process.Taking a variety of aluminium alloy components such as 5A06 and7075 as the study object,anodic oxidation treatment,hard anodic oxidation treatment and roughing treatment were used respectively,and then fluorocarbon system coatings were applied.And the compatibility and heavy-duty anticorrosion property of coatings were analyzed and studied.Through a number of indoor simulation acceleration tests and the comparison and analysis of test data,the environmental adaptability of each heavy-duty anticorrosion protection scheme was tested,and the most suitable heavy-duty anticorrosion protection process scheme for aluminum alloy components was selected.
