A device was set up to simulate the actual operation environment of ACC, and then with which, the corrosion behavior of Al-alloy 3004 and carbon steel 20# steel was comparatively studied with the emphasis in the influence of temperature, dissolved oxygen, pH and flow rate of the media on the corrosion of the two materials. After corrosion test, the surface of the two materials was characterized by scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), and X- ray diffraction (XRD). The results show that the corrosion rate of 2...
