| 摘 要： | 将分形理论引入到射流电沉积中,编程模拟了不同沉积几率时枝晶的生长形貌。基于模拟的原理,利用摆动射流电沉积,使金属离子更容易到达已沉积枝晶簇的内部而沉积,改变了枝晶的树枝状分形生长特性,制备了不同射流速度和电解液温度下的二维多孔交织的金属镍枝晶簇。结果表明：沉积几率的减小,使粒子簇的形貌转变为致密的多孔交织的组织。在摆动射流电沉积中,射流速度的增大,使枝晶簇的孔隙增大、组织均匀,多孔交织的形态更为明显。射流速度最大时,枝晶簇的形貌再次呈现致密型。分形维数随射流速度的增大逐渐减小。电解液温度的升高,使枝晶簇的形貌向致密型转变,分形维数逐渐增大。

| Abstract: | By introducing fractal theory to the jet-electrodeposition technology,the dendrite growth morphology of different deposition probabilities during the jet-electrodeposition were successfully simulated.Based on the simulation,using swinging jet-electrodeposition method,it was easier for metal ions to reach and deposit on inside of the already deposited dendrite clusters,therefore,the branch-like morphology of fractal growth was altered and the porous interlaced dendrites at different jet speeds and electrolyt... |
