| 摘 要： | 在氨基磺酸盐溶液中,采用共沉积技术制备Ni-Co/ZrO_2镀层。借助电化学方法,通过阴极线性扫描和计时电流测试,研究镀层电结晶初期共沉积行为和电化学反应过程,探究镀层成核模型;对镀层的表面形貌、微观结构进行表征。结果表明,Ni-Co/ZrO_2镀层共沉积电位大约在-0.80V左右;镀层的形核/生长过程符合受扩散控制的Scharifker-Hill瞬时成核模型;镀层表面均一致密,晶粒细小。

| Abstract: | Ni-Co/ZrO2 coating was prepared in sulfamate solution by codeposition. By means of electrochemistry, codeposition behavior and electrochemical reaction process in early stage of electrocrystallization of coating were studied by cathodic linear scanning and chronoamperometry test. Nucleation model of Ni-Co/ZrO2 coating was explored. Surface morphology and microstructure of coating were characterized. The results show that codeposition potential of Ni-Co/ZrO2 coating is about -0.80 V, and nucleation/growth process of coating is consistent with Scharifker-Hill transient nucleation model controlled by diffusion. Surface of Ni-Co/ZrO2 coating is homogeneous and compact with fine grain and good thermal stability. |
