| Abstract: | Objective To investigate effects of illumination on the NaCl-induced atmospheric corrosion of high intensity low-alloy steel in simulated marine atmosphere environment based on serious corrosion of metal materials in warm area of high humid and high radiation. Methods Photoelectric effect of corrosion products was analyzed by electrochemical and photo-electrochemical methods. Results Illumination decreased the impedance of high intensity low-alloy steel and accelerated its atmospheric corrosion. Conclusion Corrosion products of high intensity low-alloy steel exposed in illumination had semiconductor properties. Their light-generated electron and light-generated holes are involved in the electrochemical reaction of high intensity low-alloy steel substrate. |
