采用失重法研究了AISI 304和AISI 316不锈钢在热带海洋环境中的大气腐蚀动力学。采用激光拉曼光谱对腐蚀产物进行了表征，并采用扫描电镜观察了腐蚀产物的表面形貌。结果表明，随着暴露时间的增加，腐蚀速率有降低的趋势。质量损失服从经验动力学方程。n值可以间接预测不锈钢的耐蚀性。两种不锈钢的锈层成分不同，Fe 3 O 4和β-FeOOH的百分比也不同。
The atmospheric corrosion kinetics of AISI 304 and AISI 316 stainless steel in tropical marine environments is observed by weight loss. The corrosion products are identified by laser Raman spectroscopy, and surface morphology is observed by SEM. The results show that the corrosion rates tend to decrease as the exposure time increases. The mass loss obeys the empirical kinetics equation. The value of n can be used to predict the corrosion resistance of stainless steel, indirectly. The rust layer composition of the two stainless steels is different, and the percentage of Fe3O4 and β-FeOOH are also different.
