摘　　要：表面处理可有效增强零件的耐腐蚀性能,但其提升程度需借助特定腐蚀试验及相应评价方法予以判定,且所用腐蚀方法及试验结果应具备良好重现性。鉴于在接近零件实际使用环境下开展腐蚀评价耗时较长,设计合理的加速腐蚀试验条件与方法至关重要。本文从评价表面处理零件腐蚀试验条件的特点及腐蚀特点入手,讨论了表面处理零件的环境腐蚀特征及相应腐蚀试验方法、特点和评价标准。而且对表面处理零件的盐雾、加速腐蚀试验、大气环境腐蚀等方面的特点,如盐雾试验中零件摆放角度、表面水膜厚度、环境温湿度的影响、腐蚀速率等进行了分析讨论,为科学评价表面处理零件的耐腐蚀性能提供了支撑。Surface treatment can effectively enhance the corrosion resistance of parts,but its improvement degree needs to be determined by specific corrosion test and corresponding evaluation methods,and the corrosion method and test results should have good reproducibility.In view of the long time to carry out corrosion evaluation in the environment close to the actual use of parts,it is very important to design reasonable accelerated corrosion test conditions and methods.This paper discussed the environmental corrosion characteristics of surface-treated components and the corresponding corrosion test methods,characteristics and evaluation standards,starting from the evaluation of the characteristics of corrosion test conditions and corrosion characteristics of surface-treated components.Moreover,the characteristics of salt spray,accelerated corrosion test and atmospheric environment corrosion of surface-treated components,such as the placement angle of parts in salt spray test,the thickness of surface water film,the influence of environmental temperature and humidity,and the corrosion rate,were analyzed and discussed,which provided supports for the scientific evaluation of the corrosion resistance of surface-treated components.
