摘要:
为了研究商用冷轧钢板（ SPCC ）在循环盐雾腐蚀环境中的腐蚀行为并探究其腐蚀机理，通过 GMW14872 循环盐雾试验、腐蚀形貌观测及腐蚀失重法考察了 SPCC 钢的耐蚀性能，并采用光学 3D 表面轮廓仪对盐雾腐蚀后试样表面的腐蚀深度进行了表征。通过实验结果，对 SPCC 在盐雾腐蚀环境中的的腐蚀机理进行讨论，并分析腐蚀过程中 SPCC 钢的腐蚀产物转化对其腐蚀过程的影响作用。结果表明： SPCC 钢经过 24 个循环盐雾过程，宏观腐蚀形貌由 腐蚀初期的黑色、橙褐色逐渐转变为土黄色，耐腐蚀性呈现逐渐提升的趋势，腐蚀速率由 1.13 mm/a 下降到 0.62 mm/a ；随着腐蚀时间的增加， SPCC 钢的腐蚀形态逐渐由点蚀发展为均匀腐蚀，表面腐蚀深度值由 36 μ m 增加到 108 μ m ； SPCC 钢在腐蚀过程中，由于铁素体和渗碳体电位差的驱动引发了局部电偶腐蚀，腐蚀产物由腐蚀前期稳定性较差的 Fe （ OH ） 3 、 γ -FeOOH 、 β -FeOOH 逐渐转化为较为稳定的 α -FeOOH ，提高了耐蚀性。
Abstract:
： In order to study the corrosion behavior and corrosion mechanism of commercial cold-rolled steel plates （ Steel Plate Cold-Rolled Commercial ， SPCC ） in a cyclic salt spray corrosion environment ， the corrosion resistance of SPCC steel was explored by GMW14872 cyclic salt spray test ， corrosion morphology observation and corrosion weight loss method ， and the corrosion depth of the sample surface after salt spray corrosion was characterized by an optical 3D surface profiler. Based on the test results ， the corrosion mechanism of SPCC steel in the salt spray corrosion environment was discussed ， and the effect of the transformation of corrosion products on the corrosion process of SPCC steel was analyzed. The results showed that after 24 cycles of salt spray process ， the macroscopic corrosion morphology of SPCC steel gradually changed from black and orange-brown at the initial stage of corrosion to earthy yellow ， the corrosion resistance gradually increased ， and the corrosion rate decreased from 1.13 mm/a to 0.62 mm/a. With the increase of corrosion time ， the corrosion form of SPCC steel gradually developed from pitting corrosion to uniform corrosion ， and the surface corrosion depth increased from 36 μ m to 108 μ m. In the corrosion process of SPCC steel ， local galvanic corrosion was caused by the potential difference between ferrite and cementation ， and the corrosion products were gradually transformed from Fe （ OH ） 3 ， γ -FeOOH and β -FeOOH with poor stability at the early stage of corrosion into relatively stable α -FeOOH ， which improved the corrosion resistance.
