图是合金纳米复合镀层基体交界处的Ni元素和Co元素的面扫描图。由图可知脱落部位Co元素残留较多，而Ni元素残留较少，这可能是由于镀层在基体上开始沉积时，Co元素相对于Ni元素更优先沉积，因此脱落后基体表面Co元素的残留也较多。

The figure shows the surface scans of Ni and Co elements at the junction of the alloy nanocomposite plating substrate. It can be seen from the figure that more Co elements are left at the exfoliation site, while less Ni elements are left, which may be due to the fact that Co elements are deposited more preferentially compared with Ni elements when the plating starts to be deposited on the substrate, and therefore more Co elements are left on the substrate surface after exfoliation.
