The influence of four commercial corrosion‐inhibiting compounds on the atmospheric corrosion of EV31A, WE43B, ZE41A and pure Mg was studied at two hot, humid, tropical sites for test periods of 3–12 months. LPS 3 and AMLGuard significantly reduced the corrosion rates, with AMLGuard being most effective with inhibition efficiencies above 85%. In contrast, Ardrox 3961 and LPS 2 were ineffective with typical corrosion rates comparable with those of the bare alloys. Corrosion inhibition was tentatively attributed to protective durable barrier films formed by chemical adsorption for LPS 3 and AMLGuard.

商业缓蚀剂对镁合金EV31A，WE43B，ZE41A和纯镁的大气腐蚀的影响

在两个炎热潮湿的热带地区研究了三种商用缓蚀化合物对EV31A，WE43B，ZE41A和纯Mg大气腐蚀的影响，测试时间为3-12个月。LPS 3和AMLGuard显着降低了腐蚀速率，其中AMLGuard最有效，其抑制效率超过85％。相反，Ardrox 3961和LPS 2在与典型的裸合金可比的典型腐蚀速率下效果不佳。腐蚀抑制作用暂时归因于通过化学吸附LPS 3和AMLGuard形成的保护性耐用阻隔膜。
