Electrokinetic Deposition of Waterborne, Particulate FeO(OH) and MnO sub 2 on Stainless Steel Surfaces

摘要

The study forms part of a program of research into corrosion product behaviour in progress at Aktiebolaget Atomenergi. Attention is in this instance focused on the influence of electrokinetic factors upon the deposition of particulate corrosion products. The work has involved the development of experimental apparatus and techniques and the investigation of the deposition characteristics of FeO(OH) and MnO sub 2 at temperatures below 100 degC. The experimental results indicate that the deposition rate of the compounds under review depends mainly upon the zeta potential (zeta) of the particle and of the test section wall. The deposition rate attains a maximum when the zeta potential is at a minimum or zero. Deposition occurs when zeta approx.
