“…Among the preconditions for high-quality ECP, there is the formation of viscous thin surface layer of electrolyte with a quite rapid mass transport and, respectively, a high conductivity through it [16][17][18][19]25]. Therefore, to choose the polishing conditions it is necessary to get information on dependence of the transport properties of basic polishing solutions (density, viscosity, and conductivity) on their composition.…”

A new method for the electrochemical polishing (ECP) of stainless steel to be used for stable functional osteosynthesis has been developed. Implants have been polished in solutions based on trinary system H 2 SO 4 -H 3 PO 4 -H 2 O with a stepwise decrease in current density and increase in orthophosphoric acid concentration. The optimal polishing conditions (current density, solution composition, temperature and duration) have been determined. The developed method improves the quality and the mechanical properties of the surface polished. K e y w o r d s: electrochemical polishing, stainless steels, implants, and functional osteosynthesis.

“…The mechanism of electropolishing is usually explained as follows: the electropolishing effect occurs because of differential dissolution, as the current is applied, the oxidization film covering the lower peaks of the surface, which has a high specific [1]. In view of its strength and low cost, carbon steel is used widely as a material of construction in chemical industry to build pipelines, storage tanks, heat exchangers, pumps, etc [2]. However steel suffers from corrosion in electrolytes because of the presence of cementite in its structure [3,4].…”

Carbon steel has wide applications in industry (especially in petroleum industry, e.g. pipelines out from the top of distillation towers (over head pipes), pressure vessels, nozzles etc.) and domestic life. Study the phenomenon of electropolishing which is important as metallic finishing process which takes place before electroplating of metal. This work is devoted to study the electropolishing of carbon steel in phosphoric acid in presence of polymers molecules (Starch, Gelatin, Agar, Chitosan, Arabic gum, Cellulose acetate, Cellulose and Carboxymethyl cellulose sodium salt). The rate of electropolishing of carbon steel in phosphoric acid solution in case of applied various affecting factors was investigated by estimated polarization curves from values of current and voltage that were obtained from the electrochemical cell. Morphology of the specimens after the experiment is monitored using scanning electron microscope (SEM). The (SEM) micrographs support the experimental measurements and give more light on carbon steel surface. Finally, samples of industrial waste water are collected from a drain of vacuum distillation tower over head pipes in Alexandria petroleum company and ferrous ions Fe +2 concentrations are determined in case of presence and absence of polymers molecules in order to judge the role of these polymers as a corrosion inhibitors on the ability to control the corrosion on carbon steel over head pipes.
