Comment on “electrophoretic deposition-mechanisms, myths and materials” by Y. Fukuda, N. Nagarajan, W. Mekky, Y. Bao, H.-S. Kim and P. S. Nicholson (J. Mater. Sci. 39 (2004) 787)

Recently, Fukuda et al. reviewed explanations of the deposition process during electrophoretic deposition (EPD) and critically discussed our theory to derive the assumptions underlying the well-known laws by Hamaker and Aavgustinik. Reply to: Comment to "electrophoretic deposition-mechanisms, myths and materials" by P.M. Biescheuval and H. Verweij. Use of the Poisson equation. The Laplace equation has been used to determine the electric field strength in the suspension. In the comment, the authors have argued that the use of Poisson's equation together with the electro-neutrality condition is justified, because rhooverall = 0 at lest during the initial stages of deposition. However, according to Newman, "the use of both Poisson's equation and electroneutrality would be inconsistent"...
