摘要:

采用选区激光熔化(SLM)技术制备Al-Mg-Sc-Zr合金，系统研究其在铜绿假单胞菌(P. aeruginosa)作用下的微生物腐蚀行为。通过荧光显微镜跟踪观察菌体在合金表面的附着与分布状态，并统计14 d内细胞数量的动态变化。结合电化学测试、扫描电子显微镜(SEM)、白光干涉仪、X射线光电子能谱(XPS)等手段，对合金在无菌与接菌条件下的腐蚀特性及其机制进行了深入分析。结果显示，该合金在无菌环境中表现出优异的耐蚀性，表面基本无明显点蚀坑；而在接菌条件下，P. aeruginosa易在表面附着并诱发严重的局部腐蚀。其主要机制在于细菌通过从合金中提取Al和Mg的电子维持代谢活动，同时非均匀分布的生物膜形成氧浓差电池，加剧了局部腐蚀的发展，显著降低了合金的腐蚀稳定性。

Abstract：

A bulk Al-Mg-Sc-Zr alloy was fabricated by using selective laser melting (SLM) technique. Then its corrosion behavior of the alloy was investigated by immersion in Pseudomonas aeruginosa (P. aeruginosa) inoculated artificial seawater for 14 d, meanwhile the distribution of P. aeruginosa on the alloy surface was observed via fluorescence microscopy, and the trend in cell population changes was statistically analyzed. The corrosion behavior and mechanism of the alloy in both sterile and inoculated environments were investigated through electrochemical tests, scanning electron microscopy (SEM), white light interferometry, and X-ray photoelectron spectroscopy (XPS). The results demonstrated that the Al-Mg-Sc-Zr alloy exhibited excellent corrosion resistance in the sterile group, with virtually no observable pitting on the surface. In contrast, in the inoculated group, P. aeruginosa could adhere to the alloy surface and induced severe localized corrosion. P. aeruginosa could extract electrons from Al and Mg elements to sustain its metabolic activities, while oxygen concentration cells were formed inside the heterogeneous biofilm, significantly exacerbating the development of localized corrosion and reducing the corrosion stability of the alloy.

Key words： additive manufacturing Al-alloy Pseudomonas aeruginosa microbiologically influenced corrosion
