杀鱼假交替单胞菌对模拟海水流动环境下Q235碳钢腐蚀的抑制行为
, 2018 从位于中国东海的钢铁研究总院舟山海洋腐蚀研究所近海海域的海底沉积物中分离提取得到杀鱼假交替单胞菌,分别将其接种到细菌培养广口瓶和模拟海水流动环境培养器中,利用电化学工作站、扫描电镜及红外光谱仪对浸泡于两种培养体系中Q235碳钢样品的腐蚀行为进行研究。结果表明,杀鱼假交替单胞菌能抑制碳钢在海水中的腐蚀进程。样品的阻抗在广口瓶培养体系中得到了更为明显的提高,广口瓶培养体系中的碳钢样品表面覆盖着一层质地均匀且完整的生物膜;而模拟海水流动环境中碳钢样品表面的生物膜厚度不均匀 ...

, 2017 采用多弧离子镀在316不锈钢上沉积Cr Al N涂层,用X射线衍射仪(XRD)和扫描电子显微镜(SEM)表征涂层的成分和结构,纳米压痕和划痕仪分别测试涂层的硬度和结合力.通过球-盘往复式摩擦磨损试验机在海水环境下测试涂层腐蚀磨损性能,并用电化学工作站实时监测其摩擦过程中的电化学特性.结果表明:Cr Al N在有摩擦的条件下,涂层极化曲线的阳极区域存在较为明显的钝化区,抑制了涂层进一步腐蚀.在阳极电位下,涂层的摩擦系数随着加载电位的增加显著降低.随着加载电位的升高,涂层的磨损量也相应地增大.在阳极电位0 ...
