    • A composition for inhibiting corrosion of metal surfaces comprises permanganate and a very low concentration of chromium (VI). The concentration of chromium (VI) in the aqueous solution is less than about 100 micrograms per liter, and the concentration of permanganate is about 0.2% to about 20% by weight of the aqueous solution. In another embodiment of the invention, a composition for inhibiting corrosion of metal surfaces includes permanganate and acetic acid. The concentration of acetic acid in the aqueous solution is between about 0.2% and 2.0% by volume. The concentration of permanganate is about 0.2% to about 20% by weight of the aqueous solution. Other embodiments of the invention include methods of using the present sealant compositions and the resulting corrosion inhibited metal substrates. In yet another embodiment of the present invention there is provided a kit for preparing corrosion inhibiting solutions for metal treatment.
    • 用于抑制金属表面腐蚀的组合物包括高锰酸盐和非常低浓度的铬(VI)。 水溶液中铬(VI)的浓度低于约100微克/升,高锰酸盐的浓度为水溶液重量的约0.2%至约20%。 在本发明的另一个实施方案中,用于抑制金属表面腐蚀的组合物包括高锰酸盐和乙酸。 乙酸在水溶液中的浓度为约0.2%至2.0%(体积)。 高锰酸盐的浓度为水溶液重量的约0.2%至约20%。 本发明的其它实施方案包括使用本发明的密封剂组合物和所得的腐蚀抑制金属基材的方法。 在本发明的另一个实施方案中,提供了一种用于制备用于金属处理的腐蚀抑制溶液的试剂盒。
