中文摘要: 采用电沉积工艺制备了Ni-Co-Al2O3纳米复合镀层，利用显微硬度仪测定了复合镀层的硬度，考察了电流密度、纳米Al2O3浓度、电镀温度及镀液pH对镀层硬度的影响，分别借助SEM分析技术及电化学测试技术对最大硬度镀层进行微观性能及耐蚀性能进行研究。结果表明，纳米Al2O3弥散分布在镀层中，复合镀层晶粒进一步细化，耐蚀性显著提高。
Abstract:Ni-Co-Al2O3 nanocomposite coating was prepared by electro-deposition. The hardness was determined by micro-hardness tester. The effects of current density, concentration of nano-Al2O3 particle, and temperature and pH value of plating solution on hardness of coating were investigated. The microstructure and corrosion resistance of the coating with the highest hardness value were investigated by SEM and electrochemical testing. The results indicate that nano-Al2O3 particles distribute in coating, grain of composite coating is further refined and performance of corrosion resistance is obviously improved.
