| 目的 改善 Ni-ZrO2 纳米复合镀层的耐腐蚀性能。 方法 分别采用普通电沉积、旋转阴极电沉积、超声电沉积和超声-旋转阴极电沉积四种方式制备 Ni-ZrO2 纳米复合镀层,分析镀层的 ZrO2 含量和微观形貌,研究镀层的耐腐蚀性能。 结果 普通电沉积镀层的 ZrO2 含量高,但晶粒粗大,组织不够致密,腐蚀速率高,腐蚀后的微观表面存在很多大的腐蚀坑洞。 旋转阴极和超声辅助电沉积的镀层 ZrO2 含量较低,但晶粒有所细化,耐腐蚀性能提高。 超声-旋转阴极电沉积的镀层 ZrO2 含量最低,但晶粒细化程度最高,组织致密度也最好,腐蚀速率低,表面腐蚀特征不明显。 结论 超声场和旋转阴极都会影响镀层的组织结构和 ZrO2 含量,超声波和旋转阴极协同作用下的效果最为显著,制备的纳米复合镀层耐腐蚀性能最好。 |

| Objective To improve the corrosion resistance of Ni-ZrO2 nanocomposite coatings. Methods Ni-ZrO2 nanocomposite coatings were prepared by common electrodeposition, rotating cathode electrodeposition, ultrasound electrodeposition and ultrasound-rotating cathode electrodeposition. The ZrO2 content and the surface morphology of nanocomposite coatings were analyzed. The corrosion resistance of Ni-ZrO2 nanocomposite coatings was studied. Results Although the ZrO2 content of the coating prepared by common electrodeposition was high, it had coarse grain and loose structure. Its corrosion rate was high and the surface morphology was corroded with many pits or holes. The ZrO2 contents of the coating prepared by rotating cathode electrodeposition or ultrasound electrodeposition decreased. But its grains became refined and the corrosion resistance was good. The ZrO2 content of the coating prepared by ultrasound-rotating cathode electrodeposition was the lowest. But it had the highest degree of grain refinement and structure density in these four methods. The corrosion rate was the lowest and the corrosion resistance was the highest. Conclusion The ZrO2 content and microstructure were influenced by ultrasound and ultrasound-rotating in electrodeposition. The nanocomposite coatings prepared by ultrasound-rotating cathode electrodeposition exhibited excellent corrosion resistance. |
