[Abstract]:Based on the atmospheric environment data of the Wanning Marine atmosphere Test Station in recent 3 years, the equivalent conversion method is used to calculate the conversion period needed for the neutral salt fog experiment to simulate the Wanning marine atmospheric environment. The corrosion behavior of DC06 and Q235 steels in neutral salt spray test was studied by using ultra-deep cold rolled sheet DC06 and Q235 steel as experimental materials. The correlation between accelerated neutral salt spray test and outdoor exposure experiment in Wanning ocean atmosphere was studied quantitatively by grey correlation method. The results show that the corrosion kinetics curves of neutral salt spray test of DC06 and Q235 steel are in accordance with the law of power function. The grey correlation degree between neutral salt spray test and Wanning outdoor atmospheric exposure test for DC06 and Q235 steel was greater than 0.6, which was consistent with the principle of indoor and outdoor kinetics consistency. The calculated period (528ha-1) and the usual period (480ha-1) of DC06 and Q235 steel were higher than 0.6. The grey correlation degree of DC06 and Q235 steel under the conversion period (528ha-1) is higher than that of the usual period (0.60290.6050).
