研究了含Sb、Cu的耐硫酸腐蚀钢中,硫含量对腐蚀速率、腐蚀宏观形貌和微观形貌的影响。进行了全浸浸泡失重实验,对宏观形貌和扫面电镜微观形貌进行了观察。结果表明,随着硫含量的增加,腐蚀速率也逐渐升高;随着硫含量的增加,腐蚀形貌由致密转向疏松,腐蚀产物膜的厚度增大。 The effect of sulfur content on the corrosion rate, corrosion macro-morphology and micro-morphology in the sulfuric acid-resistant steels containing Sb and Cu was studied. Immersed immersion weight loss experiments were conducted, macroscopic morphology and scanning electron microscopy were observed. The results show that with the increase of sulfur content, the corrosion rate also gradually increases. With the increase of sulfur content, the corrosion morphology turns from dense to loose and the thickness of corrosion product film increases.
