摘要(Abstract)：
为提高Ni-SiC纳米镀层的耐腐蚀性能,采用射流电沉积方法,在Q235钢基体表面制备Ni-SiC纳米镀层。利用FLUENT软件仿真不同喷嘴直径对喷射镀液的速度和动能参数影响,采用扫描电子显微镜、透射电镜、X射线衍射仪和电化学工作站对不同喷嘴直径下喷射电沉积制备Ni-SiC纳米镀层的表面形貌、显微组织、腐蚀行为进行研究。当喷嘴直径为8 mm时,喷射电沉积过程镀液的射流速度和动能较其他喷嘴直径下的大,最大射流速度和动能分别为113 m/s和543 J。此参数下制备的Ni-SiC纳米镀层具有致密、均匀的表面结构,大量SiC纳米颗粒嵌入Ni-SiC纳米镀层,Ni和SiC的平均粒径分别为342 nm和73 nm。结果表明:喷嘴直径对Ni-SiC纳米镀层的腐蚀性能影响较大;当喷嘴直径为8 mm时,Ni-SiC纳米镀层具有最佳的耐腐蚀性能。适宜的喷嘴直径,可提高镀液喷射速率和动能,从而提高Ni-SiC纳米镀层的耐腐蚀性能,得到的Ni-SiC纳米镀层与其他镀层相比组织结构更致密、均匀。
