PREPARATION OF Ni-ZrO2 NANO-COMPOSITE ELECTRODEPOSITS AND ITS CORROSION RESISTANCE
Ni-ZrO2纳米复合电镀层的制备及其耐蚀性研究

A Ni-ZrO2 nano-composite were prepared by electrodeposition. The corrosion resistance of the Ni-ZrO2 nano-composite electrodeposits in 10% HCl and 10% H2SO4 solutions respectively was studied by mass-loss measurement. SEM was used to observe the morphology of various electrodeposits after corrosion test, and the relevant corrosion mechanism was discussed. The result shows that the corrosion resistance of nano-composite electrodeposits prepared under pulse current condition is obviously better than that under other conditions. The optimum ZrO2 content in nano-composite electrodeposits and preparation conditions are critical factors.
