复合电沉积法制备ZrO_2/Ni梯度功能材料的研究

Study on fabrication of ZrO 2/Ni functional gradient material by composite electrodeposition

梯度功能材料（简称ＦＧＭ）是一种新型复合材料，其成分和组织连续变化使材料获得梯度分布的功能。研究了用复合电沉积法制备ＺｒＯ２／ＮｉＦＧＭ时各种工艺参数对ＺｒＯ２颗粒在镀层中共析量的影响，探讨了ＺｒＯ２／Ｎｉ共沉积过程，并在此基础上制得了ＺｒＯ２体积分数０～２８％的梯度镀层。通过对其组织进行观察证实了其成分呈现出梯度的变化。

Functional gradient material (FGM) is a new type of composite material of which composition and microstructure vary continuously to obtain the function of gradient distribution. With the application of composite electrodeposition to the fabrication of ZrO 2/Ni FGM, the effect of the technical parameters on codeposition amount of ZrO 2 particles in the coating is studied, and the process of the codeposition of ZrO 2/Ni is discussed. A gradient layer of which the volume fraction of ZrO 2 varies from 0 to 28% was made based on the study results. The gradient distribution of its composition is verified by the observation.
