为了探究SiC和WS2微粒的共沉积对Ni镀层的组织结构、耐磨性与耐蚀性的影响,在1060铝表面制备纯Ni镀层、Ni-SiC和Ni-SiC-WS2复合镀层,利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、能谱仪(EDS)、显微硬度计、球盘磨损机以及电化学工作站对镀层的表面、截面形貌、相组成、元素含量、显微硬度进行检测与分析,对比了纯Ni镀层、Ni-SiC和Ni-SiC-WS2复合镀层的耐磨与耐蚀性能。结果表明:Ni-SiC-WS2复合镀层平整致密,镀层中SiC和WS2的质量分数分别为7.05 %和2.53 %,这导致其镍晶粒尺寸比纯Ni镀层和Ni-SiC复合镀层分别减小63.39%和21.63%。Ni-SiC-WS2复合镀层的显微硬度最高可达424.73 HV0.5 N,比纯Ni镀层和Ni-SiC复合镀层分别提高57.70%和20.46%;镀层中的WS2微粒有良好的减摩作用,使得Ni-SiC-WS2复合镀层的摩擦系数较Ni-SiC复合镀层进一步降低17.39%,且磨损率降低24.62%;Ni-SiC-WS2复合镀层的自腐蚀电流密度最小,为4.68 μA/cm2,相比于纯Ni镀层和Ni-SiC复合镀层分别减少53.85%和11.36%;Ni-SiC-WS2复合镀层具有更高的阻抗值,为112 361 Ω·cm2,与Ni镀层和Ni-SiC复合镀层相比,Ni-SiC-WS2复合镀层表现出更好的耐腐蚀性能。
In order to investigate the effects of co-deposition of SiC and WS2 particles on the microstructure, wear resistance and corrosion resistance of Ni coatings, the pure Ni coating, the Ni-SiC composite coating and Ni-SiC-WS2 composite coating were prepared on the surface of 1060 aluminum. Scanning electron microscopy (SEM), X-ray diffractometer (XRD), energy dispersive spectroscopy (EDS) and microhardness tester, friction and ball disc wear tester and electrochemical workstation were used to detect and analyze the surface and cross section morphology, phase composition, elemental contents and microhardness of the coatings, and the wear resistance and corrosion resistance of the pure Ni, Ni-SiC and Ni-SiC-WS2 composite coatings were compared. Results showed that the Ni-SiC-WS2 composite coating was flat and compact, with a mass fraction of 7.05% (mass fraction, the same below) and 2.53% for SiC and WS2, respectively. This resulted in the reduction of nickel grain size by 63.39% and 21.63%, compared with the pure Ni coating and the Ni-SiC composite coating, respectively. The microhardness of Ni-SiC-WS2 composite coating was up to 424.73 HV0.5 N, which was 57.70% and 20.46% higher than that of the pure Ni coating and the Ni-SiC composite coating, respectively. WS2 particles in the coating had good antifriction effect, which made the friction coefficient of the Ni-SiC-WS2 composite coating further reduced by 17.39% compared to Ni-SiC composite coating, and wear rate reduced by 24.62%. The self-corrosion current density of Ni-SiC-WS2 composite coating was the lowest, at 4.68 μA/cm2, which was reduced by 53.85% and 11.36%, compared with the pure Ni coating and the Ni-SiC composite coating, respectively. The Ni-SiC-WS2 composite coating had higher impedance value of 112 361 Ω·cm2, which demonstrated better corrosion resistance than the Ni coating and the Ni-SiC composite coating.
