| 摘 要： | 研究了在脉冲复合电铸过程中,当其它工艺参数一定时,镀液中纳米ZrO2颗粒含量、脉间、脉宽和阴极电流密度对复合电铸层中ZrO2复合量和沉积速率以及脉冲参数对复合电铸层表面形貌的影响,并对所制备复合电铸层的横截面进行了SEM观察和组成成分测定.结果表明,通过控制脉冲复合电铸过程中的工艺参数可以制备出由纳米颗粒复合量变化而导致其组织成分呈梯度分布的纳米功能梯度材料. |

| Abstract: | In the pulse composite electroforming,when other process parameters were remained stationary,the effects of the ZrO_(2)concentration in electrolyte,T_(on),T_(off) and the cathode current density on ZrO_(2)content in nano-composite electroforming deposits and codeposition rate were discussed.The effect of pulse parameters on surface morphology of nano-composite electroforming deposits was analyzed.Meanwhile,SEM and EDS were used for the examination of cross-section morphology and the component of nano-composite electroforming deposits.The results show that the preparation of functional gradient material(FGM) with gradient component is carried out by controlling process parameters. |
| Keywords: | pulse composite-electroforming content codeposition rate surface morphology functional gradient material(FGM) |
