Copper Plating Corrosion Study in Certain Environments
(Universitatea "Dunărea de Jos" din Galați, 2013)Copper plating was performed on nickel substrate by means of the potentiostatic electrodeposition method from a sulphate electrolyte solution. The copper coatings morphology was studied by means of the optical and ... -
Corrosion of Composite Ferro-Niobium Layers in Cobalt Matrix
(Universitatea "Dunărea de Jos" din Galaţi, 2012)The ferro-niobium composite layers in cobalt matrix were obtained by cathode depositing from electrolyte solutions on steel base. The electrolyte included in its composition cobalt sulphate and cobalt chloride, boric ... -
Effect of Current Density on Morphology and Corrosion Resistance of Epoxy Resin/Zn Layers
(Universitatea "Dunărea de Jos" din Galați, 2013)In this research we intended to obtain and characteriz composite layers by using epoxy resin (disperse phase) electrodeposited with zinc (metal matrix). The epoxy resin/Zn layers were electrodeposited at two values of ... -
Effect of Mean Diameter Size of Disperse Phase on Morphology and Corrosion Resistance of Phenol-Formaldehhyde Resin/Zn Coatings
(Universitatea "Dunărea de Jos" din Galați, 2013)The present work has the purpose of obtaining composite coatings using phenol – formaldehyde (PF) resin electrodeposited with zinc. The phenol – formaldehyde resin/Zn coatings were electrodeposited from a suspension of ... -

Electrodeposition Obtaining and Corrosion Behaviour of Phenol Formaldehyde Resin/Zinc Composite Coatings
(Universitatea "Dunărea de Jos" din Galați, 2008)The present work has the purpose of obtaining composite coatings in zinc matrix by using phenol - formaldehyde resin type NOVOLAC (RESITAL 6358/1) in the electrodeposition process of zinc. The PF resin/Zn composite ... -
Morphological Aspects and Corrosion Behaviour of Phenol Formaldehyde/Zn Composite Coatings
(Universitatea "Dunărea de Jos" din Galați, 2009)The present work has the purpose of studying morphological aspects and corrosion behaviour of pure zinc and composite coatings having zinc as metal matrix and phenol – formaldehyde resin type Novolac (RESITAL 6358/1) ... -
Researches Concerning Phase Transition of Zirconium Titanate Prepared by Electrolytic Method
(Universitatea "Dunărea de Jos" din Galați, 2006)Powder zirconium titanate ceramics obtained by an electrolytic method has been investigated. Continuous phase transition were found to occur in powder zirconium titanate above and below a major discontinuity at 1120oC±10oC. ... -
Studies and Researches Regarding the Obtaining and Characterization of Composite Nickel Coatings-Ni/Al2O3, Ni/Kaolin Electrochemically Produced
(Universitatea "Dunărea de Jos" din Galați, 2016)This study presents the composite nickel coatings electrochemically obtained using as disperse phases Al2O3 particles and kaolin. There were used Watts electrolytes, with a pH = 4, current density of 4 A/dm2, a concentration ... -
Study of Zro2/Co-Deposition with Cobalt from Chloride Electrolyte
(Universitatea "Dunărea de Jos" din Galați, 2009)The metal-matrix composites are materials in which the properties of a metallic host material are modified with addition of a second phase (ceramics) by electrodeposition process. The second phase can be hard oxides or ... -
Surfasce Roughness and Topography of Ni/Micro-Sic Layers: Influence of Current Density on Electrodeposition Process
(Universitatea "Dunărea de Jos" din Galați, 2015)The surface properties are directly responsible for the performance of engineering materials because most of failures such as friction, wear, corrosion and fatigue often take place on the material surface. Electrodeposition ...
