摘　　要：大气腐蚀问题是装备全寿命周期内的主要问题之一。研究装备在海洋大气环境下的腐蚀行为并分析主要腐蚀因素对提高装备防腐水平意义重大。在分析装备服役环境特点的基础上,阐述了装备腐蚀的主要影响因素,建立了大气腐蚀指标体系。采用灰色关联法(GRA)定性分析了海洋环境因素与装备腐蚀之间的关联程度;利用核主成分分析法(KPCA)对筛选后的指标体系进行了定量分析,提取了影响装备腐蚀的主要特征向量并优化腐蚀指标体系。结果表明,平均相对湿度、光照时间、平均温度、降水量和PH值为海洋大气环境下装备腐蚀的主要影响因素。The atmospheric corrosion of equipment is one of the main problems in the whole life cycle of equipment.It is of great significance to study the corrosion of equipment in Marine atmosphere environment and analyze the main corrosion factors.Based on the analysis of the characteristics of equipment service environment,the main corrosion factors and their effects are expounded,and the atmospheric corrosion index system is established.Grey correlation method(GRA)was used to qualitatively analyze the correlation degree between Marine environmental factors and equipment corrosion.Kernel principal component analysis(KPCA)was used to quantitatively analyze the selected index system,extract the main feature vectors affecting equipment corrosion,and optimize the corrosion index system.The results show that mean relative humidity,light time,mean temperature,precipitation and PH are the main factors affecting equipment corrosion in Marine atmosphere environment.
