摘      要：This paper studied corrosion of pure Mg and the Mg alloys EV31A,WE43B,ZE41A,coated with commercial corrosion inhibiting compounds(CICs)(LPS 3,LPS2,AMLGuard,Ardrox 3961)immersed in 3.5 wt%(0.6M)Na Cl solution saturated with Mg(OH)_(2).All four CICs reduced corrosion *** 3 resulted in zero corrosion rates and 100%inhibition in most *** 2 and AMLGuard had comparable inhibition efficiencies,whilst Ardrox 3961 had the lowest inhibition *** in corrosion rates was tentatively attributed to barrier films formed by chemical adsorption for LPS 3 and AMLGuard,and by physical adsorption for LPS2 and Ardrox 3961.
