Ni-PTFE-SiC composite coating was deposited by multi-physics coupled deposition in a Watt nickel plating bath with PTFE-SiC mixed particles. The microstructure and the nanoparticles distribution of the composite coatings were characterized on a field emission scanning electron microscopy (FESEM), energy spectrometer (EDS), X ray diffraction (XRD). The adhesion strength between the coating and the substrate was measured by the scratch method. The corrosion resistance of the composite coating in the 3.5% NaCl solution was studied by the Tafel polarization method and the electrochemical impedance method. The results showed that multi-physics coupled deposition improved the uniformity of the nanoparticles distribution in the Ni-PTFE-SiC composite coating, which enhanced the preferred orientation (111) and the (220) crystal plane of the composite coating. The adhesion strength and corrosion resistance of Ni-PTFE-SiC composite coating were enhanced by multi-physics coupled deposition....

Ni-PTFE-SiC复合涂层的多物理场耦合沉积及其性能研究

在具有PTFE-SiC混合颗粒的Watt镍镀液中通过多物理场耦合沉积来沉积Ni-PTFE-SiC复合涂层。利用场发射扫描电子显微镜（FESEM），能谱仪（EDS），X射线衍射（XRD）对复合涂层的微观结构和纳米颗粒分布进行了表征。通过刮擦法测量涂层和基材之间的粘合强度。采用Tafel极化法和电化学阻抗法研究了复合涂层在3.5％NaCl溶液中的耐蚀性。结果表明，多物理场耦合沉积提高了Ni-PTFE-SiC复合涂层中纳米颗粒分布的均匀性，这增强了复合涂层的优选取向（111）和（220）晶面。通过多物理场耦合沉积提高了Ni-PTFE-SiC复合涂层的附着强度和耐蚀性。
