文章亮点

(1) α-AlFeMnSi相与Al基体之间的微电偶效应是导致Al–Zn–Mg合金局部腐蚀的主要因素。

(2) α-AlFeMnSi相中Fe、Mn和Si元素扩散降低了其与Al基体之间的微电偶效应。

(3) 热处理工艺可促进Mn元素扩散至Al基体并提升高强铝合金耐局部腐蚀性能。

中文摘要

Al–Zn–Mg合金强度高且具备良好的成型和焊接性能，已广泛应用于先进装备制造中，然而服役过程中易发生局部腐蚀失效，对构件的可靠性和安全性造成威胁。本文通过第一性原理计算和扫描开尔文探针显微镜(SKPFM)研究了α-AlFeMnSi相元素扩散对Al–Zn–Mg合金局部腐蚀行为的影响。材料建模和计算的结果表明，α-AlFeMnSi相中Fe、Mn、Si元素含量降低导致α-AlFeMnSi相/Al基体之间的平均功函数差由0.232 eV减小至0.065 eV。SKPFM实验观测到α-AlFeMnSi相中Fe和Si元素含量降低时，α-AlFeMnSi相/Al基体之间的平均Volta电位差由648.370 mV降低至432.383 mV。因此，α-AlFeMnSi相中元素的扩散降低Al–Zn–Mg合金的微电偶腐蚀敏感性。基于铝中原子扩散计算，热处理工艺（>550°C）有利于α-AlFeMnSi相中Mn元素扩散进入基体，降低α-AlFeMnSi相/Al基体微电偶腐蚀效应，提升Al–Zn–Mg合金耐局部腐蚀性能。

Abstract

Abstract

First principles calculations and scanning Kelvin probe force microscopy (SKPFM) were used to investigate the effect of elements migration of α-AlFeMnSi phase on micro-galvanic corrosion behavior of Al–Zn–Mg alloy. The simulation results showed that the average work function difference between the α-AlFeMnSi phase and Al matrix decreased from 0.232 to 0.065 eV due to the synchronous migration of elements Fe–Mn–Si. Specifically, as the elements Fe–Si migration during the extrusion process, the average Volta potential difference detected by SKPFM between the α-AlFeMnSi phase and Al matrix dropped down to 432.383 mV from 648.370 mV. Thus, the elements migration reduced the micro-galvanic corrosion sensitivity of Al–Zn–Mg alloy. To reach the calculated low micro-galvanic tendency between α-AlFeMnSi phase and Al matrix, the diffusion of Mn should be promoted during extruding process.
