主要介绍了汽车腐蚀的因素,明确了汽车防腐的基础设计,针对具体车型设计中开展干湿区分区、电泳膜厚设计以及在制造工艺环节中对基础防腐设计的影响因素和预防对策做了进一步阐述,通过案例展示了提前设计和试验对防腐设计的重要性。

This paper introduces the factors of automobile corrosion and defines the basic design of automobile corrosion prevention.In the design of specific vehicle models,dry-wet distinguishing area and electrop horesis film thickness design should be carried out,as well as the influencing factors and p reventive measures of basic anti-corrosion design in the process of manufacturing.The importance of early design and test to anti-corrosion design was demonstrated through cases.
