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.
