主 题：co-electrodeposition functionally graded composite coating microhardness wear resistance adhesion
摘 要：For the first time,functionally electroless nickel plated ZrO2(NCZ)graded Ni-NCZ composite coating has been successfully co-electrodeposited from a bath with gradually increasing of stirring *** showed that co-electrodeposition in a bath with stirring rate of250r/min results in the maximum co-electrodeposited particle content and the best particle *** produce NCZ graded Ni-NCZ composite coating,the stirring rate was continuously increased from0to250r/*** electroplated coating had a continuous gradient increasing of co-electrodeposited NCZ content from substrate towards the *** results showed that with increasing the co-electrodeposited NCZ particles content in Ni matrix,microhardness increases from interface towards the surface of the *** crystallite size of Ni matrix and higher co-electrodeposited hard particles content were recognized as the reasons of microhardness *** test revealed that the functionally graded composite coating shows more excellent adhesion to the substrate compared with the ordinary distributed Ni-NCZ on the same *** result is attributed to lower mechanical mismatch between coating and substrate in the functionally graded composite coating with respect to the uniformly distributed *** results of wear resistance measurements reveal that wear resistance of functionally graded Ni-NCZ is higher than that of ordinary distributed composite coating.
