Abstract

A new designing idea was proposed for the high corrosion-resistance magnesium (HCR Mg) alloy based on dissolution-ionization-diffusion-deposition (DIDD) model. HCR Mg alloy consists of low-alloying element (LA) and micro-alloying element (MA), characterized as “Mg-LA-MA” alloying system. The downwards-magnifying effect of MA-LA-Mg on the nucleation played a key role in achieving passivation behavior. The designed HCR Mg alloy (Mg-3Nd-1Gd-0.6In) showed superior corrosion resistance (near AA2024 alloy) and good mechanical performance (UTS, 259.30 ± 0.27 MPa). Overall, a universal way for designing new alloy systems with superior corrosion resistance was proposed, promising for future applications.
