The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial metal ion concentration, COD and time of electroprocessing were investigated. The optimum pH was f...

In this work, electrophoretic deposition (EPD) is reported to form gallium thin film with high deposition rate and low cost while avoiding the highly toxic chemicals typically used in electroplating. A maximum deposition rate of ~0.6 μm/min, almost one order of magnitude higher than the typical value reported for electroplating, is obtained when employing a set of proper deposition parameters. ...

A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600...

Electrodeposition is the method of plating metal into another by hydrolysis generally to protect against corrosion metal. In Zinc Electroplating, deposited on steel, where acts as a sacrificial element that enhances Steel’s life. The zinc electroplating methods are mostly affected process parameters such current, temperature, voltage, etc. Hydrogen absorbed in plated layer and later it causes c...

The paper analyzes the technological process of electro-electroplating-mechanical coating in comparison with a similar without mechanical impact on formed coating.
