分别测试了新型F级船用低温钢板表面生成不同氧化物后的往复摩擦行为,并结合白光干涉仪以及扫描电子显微镜分别对钢样的显微组织形貌和磨痕形貌进行了表征.结果 表明:γ-FeOOH氧化层钢样、原始钢样、Fe3O4氧化层钢样的耐磨蚀性能依次变高.其中,致密完整的Fe3O4氧化层钢样的磨损量最低,磨痕轮廓深度和尺寸都最小,表面以粘着磨蚀为主,耐蚀性也最好;γ-FeOOH氧化层微观结构较为疏松,摩擦系数最小,但是在摩擦腐蚀的协同作用下磨损量最大,磨损机理皆以磨粒磨损为主;未处理钢样的耐磨蚀性能处于两种预氧化钢样之间,以磨粒磨损为主,且表面有更多的犁沟和凹坑.

采用失重法、电化学法及表面分析测试研究了农林废弃物核桃青皮提取物(WGHE)与阴离子表面活性剂十二烷基磺酸钠(SLS)对冷轧钢在2.0 mol/L H3PO4介质中的缓蚀协同效应,并对WGHE中的缓蚀有效成分进行了探究.结果 表明:单独的WGHE、SLS具有中等程度的缓蚀性能,50℃时100 mg/L的缓蚀率仅为50%左右;WGHE/SLS复配后缓蚀率不断上升,最高缓蚀率可达95.3%,两者之间存在显著的缓蚀协同效应,缓蚀协同效应系数随温度的升高而增大.WGHE/SLS复配缓蚀剂更能同时有效抑制阴极和阳极

探究了CO2湿气环境中P110SS抗硫钢在不同温湿度下的S腐蚀特征及腐蚀机理.采用X射线光电子能谱(XPS)和扫描电子显微镜(SEM),对P110SS钢表面腐蚀产物膜的化学组成、微观形貌及厚度及去除腐蚀产物后基体的微观形貌进行了表征.结果 表明:在60℃、相对湿度为30%的条件下,S不会参与腐蚀反应,但腐蚀环境中的Cl和CO2会导致抗硫钢发生局部腐蚀;当相对湿度升高至60%和90%时,S参与了腐蚀的阴极反应,生成FeS,并导致抗硫钢发生全面腐蚀.在80℃、相对湿度为30%的条件下,S也参与腐蚀的阴极反应,
