摘　　要：用SEM分析了诸如电铸时间、电流密度、镀液中纳米ZrO2颗粒悬浮量、电流形式和阴极表面粗糙度等因素对Ni ZrO2纳米复合电铸层微观形貌的影响。结果表明,电铸时间、阴极电流密度以及镀液中纳米ZrO2悬浮量对纳米复合电铸层微观形貌有一定程度的影响,采用脉冲电沉积工艺有助于获得表面光滑平整、显微组织均匀致密的纳米复合电铸层。The effect factors, such as time, current density, ZrO_2 concentration in electrolyte, current form and surface roughness of cathode on the micro-morphology pattern of Ni-ZrO_2 nano-composite electroforming deposits were analyzed by SEM. Results show that the micro-morphology of Ni-ZrO_2 nano-composite electroforming deposit depends on the chosen of the time, current density and ZrO_2 concentration in electrolyte. The Ni-ZrO_2 nano-composite electroforming deposit with a flat surface and compact microstructure were obtained by the pulse electroforming.
