Abstract The SiC content in nickel–cobalt/carborundum (Ni–Co/SiC) coatings has vital effects on the corrosion resistance. In this study, a supergravity field was introduced during electrodeposition to fabricate Ni–Co/SiC coatings with improved corrosion resistance. The effects of the supergravity field on the morphology, SiC content, microhardness, wear resistance, and corrosion resistance of the coatings were explored. The experimental results indicate that the addition of an appropriate supergravity field results in coatings with smoother surface morphology, greater SiC content, and improved microhardness and wear resistance compared to the coating deposited under normal gravity. The remarkable enhancement in the corrosion resistance of the Ni–Co/SiC coating fabricated under supergravity field was demonstrated via electrochemical tests.

通过超重力场辅助电沉积形成的镍钴/碳化硅涂层增强的耐腐蚀性

摘要 镍钴/碳化硅 (Ni-Co/SiC) 涂层中的 SiC 含量对耐腐蚀性能有重要影响。在这项研究中，在电沉积过程中引入了超重力场来制造具有更高耐腐蚀性的 Ni-Co/SiC 涂层。研究了超重力场对涂层形貌、碳化硅含量、显微硬度、耐磨性和耐腐蚀性能的影响。实验结果表明，与在正常重力下沉积的涂层相比，添加适当的超重力场导致涂层具有更光滑的表面形态、更高的 SiC 含量以及提高的显微硬度和耐磨性。通过电化学测试证明了在超重力场下制备的 Ni-Co/SiC 涂层的耐腐蚀性能显着提高。
