    Corrosion Resistance of Fe-Based Amorphous/Nanocrystal Coating Prepared by Arc Spraying

      摘要
    • 摘要: 采用高速电弧喷涂技术在45钢基体上制备了FeCrWNbSiB非晶纳米晶涂层和1Cr18Ni9Ti涂层, 采用扫描电镜和X射线衍射仪等对非晶纳米晶涂层的组织结构进行了分析, 利用电化学手段对两种涂层的耐腐蚀性能进行研究。结果表明: 非晶纳米晶涂层主要由非晶相和α(Fe, Cr)纳米晶相组成, 非晶相的体积分数为57.2%, 纳米晶平均尺寸为29.2 nm; 该涂层呈层状结构, 结合紧密, 孔隙率为3.8%; 与1Cr18Ni9Ti涂层相比, 非晶纳米晶涂层的耐腐蚀性能较好。

       

      Abstract: FeCrWNbSiB amorphous/nanocrystal coating and 1Cr18Ni9Ti coating were fabricated on 45 steel substrate by high velocity arc spraying. The microstructure of FeCrWNbSiB coating was observed by scanning electron microscopy and the phases was characterized by X-ray diffractometer. The corrosion resistance of two coatings was inspected by means of electrochemical methods. The results show that FeCrWNbSiB coating was composed of amorphous phase and α(Fe, Cr) nanocrystal phase. The volume fraction of amorphous phase in the coating was 57.2% and the average grain size of the nanocrystal was 29.2 nm. The coating with lamellar structure had porisity about 3.8%. FeCrWNbSiB amorphous/nanocrystal coating exhibited better corrosion resistance than that of 1Cr18Ni9Ti coating.
