| 摘 要： | 通过电化学方法在带有局域应力的铜表面电镀形成一层铝膜.实验表明沉积在铜表面的铝颗粒形状与局域应力缓释有直接的联系。局域应力越大，形成颗粒越大，形状呈针状。随着局域应力的降低，颗粒度明显降低，颗粒形状逐渐向球形过渡。结果表明基体的局域应力可以改变沉积颗粒的形状，促进沉积颗粒的形核与增长.

| Abstract: | The aluminum-coating layer was formed on copper substrate with local strain region by using electrodeposition method.It was shown that the particle shape deposited on the copper substrate was very sensitive to the strain extent of substrate.The larger and more needle-like aluminum particles were formed on the substrate region with the lager local strain,indicated that substrate local strain might change the shape of the deposited particles and helped the nucleation and the growth of deposited particles. |

| Keywords: | electrodeposition strain energy particle shape |
