| 摘 要： | 研究了电流密度、钝化时间和钝化液温度对Zn-Ni钝化层抗腐蚀性能的影响.结果表明:在Zn-Ni电沉积过程中,电流密度增大可提高阴极电沉积速率.当电流密度为2A/dm2时得到的Zn-Ni合金镀层抗腐蚀性能最佳.钝化液的温度为20℃时,钝化层的抗腐蚀性能不佳;随着温度升高到30℃左右,钝化层达到最佳的抗腐蚀性能.在钝化时间为60s时,Zn-Ni钝化层中性盐雾试验可以达到160h.

| Abstract: | The influence of current density,passivation time and temperature on the corrosion resistance of Zn-Ni coating was studied.The results showed that the current density could accelerate the cathodic electro deposition rate.When the current density is 2 A/dm2,the coating obtains optimum corrosion resistance.When the solution temperature is 20 ℃,the corrosion resistance of the passivation layer is not good.The passivation layer achieves the best corrosion resistance as the temperature increase to 30 ℃.The corrosion resistance of the coating is up to 160 hours when the passivation time is 60 s. |
