摘要

研究了 Mg-9Gd-3Y-2Zn-0.5Zr 合金在模拟沿海储存环境中的长期腐蚀行为。结果表明,Mg-9Gd-3Y-2Zn-0.5Zr 合金中的 Mg12 (Y, Gd) Zn 相与 α-Mg 形成电偶,Mg12 (Y, Gd) Zn 相作为阴极在腐蚀起始期加速了 α-Mg。阳极的腐蚀随后转化为阳极的腐蚀性溶解。随着 Mg12 (Y, Gd) Zn 相的溶解,Gd 和 Y 等元素逐渐分布到整个腐蚀产物层中,通过形成致密的 Gd2O3 和 Y2O3 提高了腐蚀产物层的保护性能。

Corrosion behavior of the second phase in Mg–9Gd–3Y–2Zn–0.5Zr alloy under simulated coastal storage environment
The Mg–9Gd–3Y–2Zn–0.5Zr alloy was studied for its long-term corrosion behavior in a simulated coastal storage environment. The results show that the Mg12 (Y, Gd) Zn phase in the Mg–9Gd–3Y–2Zn–0.5Zr alloy forms a galvanic couple with α-Mg, and the Mg12 (Y, Gd) Zn phase acts as a cathode to accelerate α-Mg during the corrosion initiation period. The corrosion of the anode is subsequently transformed into corrosive dissolution of the anode. With the dissolution of the Mg12 (Y, Gd) Zn phase, elements such as Gd and Y are gradually distributed into the entire corrosion product layer, improving the protective performance of the corrosion product layer by forming dense Gd2O3 and Y2O3.

期刊介绍: npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
