摘要: 通过扫描电镜结合能谱分析，对Aermet100钢、300M钢和超高强不锈钢3种超高强钢在绳状青霉、黄曲霉和杂色曲霉3种单一菌种中的腐蚀形貌进行观察分析，结果表明：3种超高强钢试样进行84 d霉菌试验后，试样表面都发生一定的腐蚀。其中，在杂色曲霉环境中，3种超高强钢腐蚀都比较严重。采用扫描Kelvin探针测试技术，研究了3种超高强钢在杂色曲霉环境中的腐蚀行为，结果表明：杂色曲霉对Aermet100钢和300M钢的腐蚀行为有一定促进作用；而杂色曲霉形成的生物膜覆盖在超高强度不锈钢表面，抑制其腐蚀的发展。

Abstract：The corrosion morphology of Aermet100 steel, 300M steel and ultra high strength stainless steel was observed in the Penicillium funiculosum, Aspergillus flavus and Aspergillus versicolor environments by Scanning Electron Microscopy (SEM) equiped with Energy Dispersive X-ray Spectroscopy (EDS). The results showed that corrosions occur on the surface of all the three steel specimens after mold tests for 84 days, but the corrosion is serious in the Aspergillus versicolor environment. The corrosion behavior of three ultra high strength steels in the Aspergillus versicolor environment was investigated by Scanning Kelvin Probe (SKP) measurement. The results showed that the corrosion behavior of the Aermet100 and 300M steels is promoted in the Aspergillus versicolor environment, but the corrosion behavior of the ultra high strength stainless steel is inhibited due to forming the biofilm on the surface.

Key words： Aermet100 steel 300M steel ultra high strength stainless steel penicillium funiculosum Aspergillus flavus aspergillus versicolor scanning Kelvin probe
