Exploratory corrosion tests on alloys in molten salts at 900 C
- Solar Energy Research Institute, Golden, CO (USA)
The results of exploratory corrosion tests on sixteen different alloys at 900 C in molten eutectic sodium-potassium carbonate, in molten eutectic sodium-potassium-magnesium chloride and in molten sodium hydroxide are presented. The salts and many of the alloys were chosen for this study based on results reported in the literature; other alloys that were tested had no previously reported testing in these salts. These screening tests were done for times ranging from two days to twenty days and the corrosion rate was monitored by making weight and thickness measurements as well as by observations on the appearance of the coupons. The apparatus and test procedures are discussed as well as the applications for these salts in solar energy technology. It was found that the carbonate salt was the least corrosive to alloys of the three salts and that several of the alloys showed sufficient compatibility with the salt to warrant further study.
