图 是合金纳米复合镀层在脱落部位的镀层。基体交界处的局部放大图，其中（a）500倍,（b）2000倍，对比硬铬镀层脱落界面处，由图（a）可知脱落后基体表面略显粗糙，残留合金纳米复合镀层，界面有明显的过渡区域，整体表现为脆性断裂，由于合金纳米复合镀层还是脆性镀层，在受力变形时塑性变化不大，发生脆性断裂。对过渡区域放大分析，如图（b）所示，镀层中夹杂球状组织。

Figure is the plating of alloy nanocomposite plating at the exfoliated area. The local magnification of the junction of the substrate, where (a) 500 times, (b) 2000 times, compared with the hard chromium plating off the interface, from the figure (a) can be seen off the surface of the substrate slightly rough, residual alloy nanocomposite plating, the interface has a clear transition area, the overall performance of brittle fracture, because the alloy nanocomposite plating or brittle plating, plasticity changes little when deformed by force, brittle fracture occurs . Enlarged analysis of the transition region, as shown in Figure (b), the plating layer is interspersed with spherical organization.
