| 摘 要： | 向Zn-Ni合金镀液中加入AI2O3溶胶,获得了Zn-Ni-AI2O3复合镀层。研究了A12O3溶胶的体积分数对镀层的相结构、表面形貌、横截面形貌、显微硬度、耐磨性及耐蚀性的影响。结果表明:当A12O3溶胶的体积分数低于6 mL/L时,不会对镀层的相结构产生影响。但当A12O3溶胶的体积分数较高时,会改变镀层的相结构,并影响镀层的致密性。当AI2O3溶胶的体积分数为6 mL/L时,镀层的耐磨性和耐蚀性均最佳。

| Abstract: | Zn-Ni-AI2O3 composite coatings were prepared from Zn-Ni plating bath containing AI2O3 collosol.The effect of the volume fraction of AI2O3 collosol on the phase structure,surface morphology,cross-section morphology,microhardness,wear resistance and corrosion resistance of the coatings was studied・The results showed that there was no obvious effect on the phase structure when the volume fraction of AI2O3 collosol was lower than 6 mL/L.However,the phase structure and compactness of the coatings changed when the volume fraction of AI2 O3 collosol was relatively higher.When the volume fraction of AI2O3 collosol was 6 mL/L,the coating possessed the best wear resistance and corrosion resistance. |
