采用动电位扫描（PDS）和电化学阻抗谱（EIS）技术研究了化学镀镍SiC颗粒增强挤压铸造铝基复合材料在充气和脱气氯化物溶液中的腐蚀行为。利用光学显微镜、扫描电镜（SEM）、能谱仪（EDS）和X射线衍射仪（XRD）对复合材料的微观结构和界面进行了表征。已经观察到，SiC颗粒的化学镀镍涂层不是改善其在含有卤化物溶液的结构应用中的耐腐蚀性的有效方法。
The corrosion behavior of electroless Ni coated SiC particle reinforced squeeze cast aluminum based composite was investigated by potentiodynamic scanning (PDS) and electrochemical impedance spectroscopy (EIS) techniques in aerated and deaerated chloride solutions. Microstructural and interfacial characterization of the composite was carried out by using an optical microscope, scanning electron microscope (SEM), energy dispersion spectroscopy (EDS) and X-ray diffractometer (XRD). It has been observed that electroless Ni coating of SiC particles is not an effective method to improve its corrosion resistance in structural applications containing halide solution.
