Growth of three-dimensional silver fractal electrodeposits under damped free convection
Quasispherical three-dimensional Ag electrodeposits grown at constant potential and damped free convection exhibit a quasi-isotropic radial growth up to a critical radius r<sub>c</sub>≃0.3 cm and a mass fractal dimension D<sub>M</sub>=2.5. For r≫r<sub>c</sub>, D&l...

| Resumo: | Quasispherical three-dimensional Ag electrodeposits grown at constant potential and damped free convection exhibit a quasi-isotropic radial growth up to a critical radius r<sub>c</sub>≃0.3 cm and a mass fractal dimension D<sub>M</sub>=2.5. For r≫r<sub>c</sub>, D<sub>M</sub>→3. The product v<sub>r</sub>η’ is nearly constant, v<sub>r</sub> being the radial growth velocity, and η’ the apparent medium viscosity. It appears that v<sub>r</sub> is determined by the Laplacian field operating between cathode and anode. |
