摘要:

通过模拟海南滨海大气环境来研究棘孢曲霉对5A02铝合金的腐蚀行为影响机理。利用平板培养法筛选出棘孢曲霉，将其孢子悬浮液滴到试样表面并设置对照组，置于30 ℃恒温箱中，利用扫描电子显微镜(SEM)、能谱仪(EDS)和X射线光电子能谱(XPS)对试样表面腐蚀形貌和成分进行分析，并观察霉菌的生长状态。使用电化学工作站及扫描Kelvin探针(SKP)分析铝合金表面不同时间棘孢曲霉作用下的腐蚀电位。结果表明，棘孢曲霉会对铝合金材料造成局部腐蚀，腐蚀产物主要由AlO(OH)、Al₂O₃和MgO组成。棘孢曲霉生命活动会产生以草酸为主的多种有机酸，造成环境pH值出现先降低后上升的趋势，可加速腐蚀过程。有菌组的电位变化幅度更大且整体电位较无菌组更负，且有菌组电位随着时间的变化先升高后降低。腐蚀机理主要为霉菌代谢产物腐蚀和氧浓差腐蚀，Cl^-起到促进霉菌生长和加速腐蚀的作用。

Abstract：

To study the influence of Aspergillus aculeatus on the corrosion behavior of Al-alloys, the single colony of Aspergillus aculeatus was isolated and screened from the petri dishes exposed to the coastal atmospheric environment of Hainan Island. The diluted spore suspension of Aspergillus aculeatus with concentration of 1 × 10⁵ /mL was sprayed on the surface of 5A02 Al-alloy samples as groups inoculated with fungi, and sterile control groups were also set up, thereafter, which all placed in a 30 ℃ incubator for selected period of time, while the pH and acid concentration of the bacterial solution were measured intermittently. The test samples were characterized using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) in terms of their surface morphology and composition, and the growth of fungi was also observed. The corrosion potential of the Al-alloys surface under the action of Aspergillus aculeatus for different time were analyzed by electrochemical workstation and scanning Kelvin probe (SKP). Results indicated that Aspergillus aculeatus caused localized corrosion of the Al-alloy samples, their corrosion products mainly composed of AlO(OH), Al₂O₃, and MgO. The metabolic activities of Aspergillus aculeatus produced various organic acids, primarily oxalic acid, leading to a trend of decreasing and then increasing in the surrounding pH, thereby promoting the corrosion of the Al-alloy. The range of potential change of the group with fungi was greater, with overall potentials more negative than that of the sterile group. The potential of the group with fungi, initially increased and then decreased with time. The corrosion mechanisms primarily involved fungi metabolite corrosion and oxygen-concentration cell corrosion, while the chloride ions play a role in facilitating the growth of fungi and accelerating the corrosion.
