目的：研究有机-无机纳米聚硅氧烷涂料的耐蚀性。方法将涂层试样制作划痕后,采用盐雾试验方法和盐溶液周浸试验方法进行加速腐蚀试验,采用最大剥落值对涂层剥落程度进行量化考核。结果获得了4种涂料在试验环境下的腐蚀失效模式、失效过程、失效程度、以及涂层损伤随加速腐蚀时间的变化规律等方面的试验数据。结论在盐雾试验中,涂层的失效模式主要是剥落,盐溶液周浸试验主要是剥落和鼓泡。在盐雾腐蚀环境下,3#涂料耐蚀性最佳,在周浸腐蚀环境下1#涂料耐蚀性最佳。采用最大剥落值对涂层的剥落程度进行量化考核是可行的。

Objective To study the corrosion resistance of organic-inorganic nano polysiloxane coatings. Methods Ac-cording to the salt spray test method and salt solution alternate immersion test method, the accelerated corrosion tests were conducted on the coated samples with scratches. The maximum peeling value was used to quantitatively assess the peeling degree of coatings. Results Corrosion failure mode, corrosion degradation process, corrosion damage extent, and the change disciplinarian of corrosion damage extent with the accelerated corrosion time were obtained for the four kinds of coat-ings in the test environment. Conclusion The major failure mode of coatings in salt fog test was peeling, while the major modes in salt solution alternate immersion test were peeling and blistering. In the salt spray corrosion environment, 3# coat-ing had the best corrosion resistance, and in the alternate immersion corrosion environment, 1# coating had the best corro-sion resistance. Using the maximum peeling value to quantitatively assess the peeling degree of coatings was practical.
