Abstract This work presents the results of a systematic screening for magnesium corrosion inhibitors. The ability to form stable soluble complexes with Fe ii/iii was considered on first place when choosing the compounds for hydrogen evolution tests. Inhibiting effect of 151 individual compounds was tested towards six alloys (AZ31, AZ91, AM50, WE43, ZE41 and Elektron 21) and three grades of pure magnesium. Newly identified and previously reported inhibitors are ranked by their inhibiting efficiency and compared with Cr (VI) reference. A number of new inhibitors are discovered with efficiency exceeding that of chromate.

镁缓蚀剂综合筛选

摘要 这项工作展示了对镁腐蚀抑制剂进行系统筛选的结果。在选择用于析氢测试的化合物时，首先考虑与 Fe ii/iii 形成稳定的可溶性复合物的能力。测试了 151 种单独化合物对六种合金（AZ31、AZ91、AM50、WE43、ZE41 和 Elektron 21）和三个等级的纯镁的抑制作用。新发现的和以前报道的抑制剂按其抑制效率排序，并与 Cr (VI) 参考进行比较。发现了许多效率超过铬酸盐的新抑制剂。
