This document specifies a method for assessing the corrosion resistance of metals by an alternate immersion test in salt solution, with or without applied stress. The test is particularly suitable for quality control during the manufacture of metals including aluminium alloys and ferrous materials, and also for assessment purposes during alloy development. Depending upon the chemical composition of the test solution, the test can be used to simulate the corrosive effects of marine splash zones, de-icing fluids and acid salt environments. The term “metal” as used in this document includes metallic materials with or without corrosion protection. This document is applicable to — metals and their alloys, — certain metallic coatings (anodic and cathodic with respect to the substrate), — certain conversion coatings, — certain anodic oxide coating, and — organic coatings on metals.

它是将产品在盐雾和湿热两种环境条件下交替转换,最后考核整机产品的电性能和机械性能有无变化。图3 GB/T 10125中4种盐雾测试方法的对比4.4 影响因素影响盐雾试验结果的主要因素包括:试验温湿度、盐溶液的浓度、样品放置角度、盐溶液的pH值、盐雾沉降量和喷雾方式等。1) 试验温湿度 温度和相对湿度影响盐雾的腐蚀作用。金属腐蚀的临界相对湿度大约为70%。...
研究结果表明:钢板与水平线成45度角时,每平方米的腐蚀失重量为250 g,钢板平面与垂直线平行时,腐蚀失重量为每平方米140 g。GB/T 2423.17-93标准规定:平板状样品的放置方法,应该使受试面与垂直方向成30度角。pH值pH值越低,溶液中氢离子浓度越高,酸性越强腐蚀性也越强。中性盐雾试验(NSS) pH值为6.5~7.2。由于受到环境因素的影响,盐溶液的pH值会发生变化。...
