摘　　要：文章研究了铝及铝合金不同表面处理膜层在40℃±2℃模拟海水中浸泡后光泽、色差的变化,通过研究不同表面处理膜层在模拟海水中的耐盐水性能,旨在为GB/T 8013系列标准的修订提供依据。试验结果表明,在温度为40℃±2℃的模拟海水中浸泡240h后,粉末膜层(砂白、砂棕)轻微失光,阳极氧化、电泳、氟碳膜层无失光;除粉末砂棕有很轻微变色,其余膜层均无变色;阳极氧化、电泳、粉末、氟碳膜层均未出现生锈、起泡、脱落和裂纹等现象。Based on the research on saltwater resistance of different surface treatment films in simulated seawater, this paper presents the change of gloss and color difference of different surface treatment coatings on aluminium and its alloys, which aims to provide the basis for the standard revision of GB/T 8013. The results shows that, after the seawater immersion at the temperature of 40℃±2℃ for 240 h, the powder coatings （sandy white and sandy brown） shows a slight loss of gloss, and there＇ s no loss of gloss in anodic oxide coatings, electrophoretic coatings and PVDF coatings. Other coatings does not fading except for a slight change of color in sandy brown powder. There＇ s no evidence of rusting, bubbling, cracking or falling off in all the coatings.
