| 摘 要： | 研究了在复合电铸过程中,当其它工艺参数一定时,复合电铸层的沉积速率及其厚度随时间的变化趋势,以及复合电铸层表面微观形貌随电沉积时间的变化趋势。测定了复合电铸层的组织成分,并就纳米颗粒在复合电铸层表面和横截面上分布的均匀性进行了评价。结果表明,复合电铸层表面平整,组织均匀致密,其组成主要是镍和所复合的纳米颗粒,纳米颗粒较为均匀地分散在复合电铸层中。

| Abstract: | In the composite electroforming,when other process parameters were remained stationary,the variable tendency of codeposition rate and thickness of nano-composite electroforming deposits were investigated.SEM and EDS were used for the examination of surface morphology and the component of nano-composite electroforming deposits.Distribution of nanoparticles in surface and cross-section of nano-composite electroforming deposits was surveyed.Results indicate that the nano-composite electroforms composed by matrix metal Ni and ZrO_2 nanoparticles exhibit a smooth surface and compact microstructure,the nanoparticles are dispersed inside the metallic matrix. |

| Keywords: | composite-electroforming nanoparticle surface morphology structure content uniformity |
