Behavior of Ni/al2O3 Nanocomposite Thin Layers in Corroding Environment
(Universitatea "Dunărea de Jos" din Galați, 2009)
This paper investigates the effects of adding alumina nanoparticles in the
electrolyte bath on surface topomorphologies and structure of electrodeposited
nickel. The influence on the corrosion process in NaCl solutions ...
Time Analysis of King Mattehias the IST Sculptural Group
(Universitatea "Dunărea de Jos" din Galați, 2010)
The paper presents a study on the degradation of the King Matthias I sculptural
group caused by environment factors and influenced by the casting technology and
by the assembling method. During this study, samples from ...
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 ...
Characterisation of CVD Niobium Carbine Coatings on Hard Carbide Substrate
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
Hard coatings are often used for mechanical properties such as wear and
friction resistance. The corrosion behaviour may also be an important criterion for
industrial applications of these coatings. In this paper, the ...
Obtaining and Characterizing TIN-LEAD Coatings on Steel Band
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The experimental research was at the basis of the hot immersion coating
technology with Sn-Pb alloy of the steel bands presented in the study. The
characterization of these layers was achieved through microscopic analyses ...
Investigation of Corrosion Protection by Chemically Applied Patina on Artistic Bronzes
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
Increase of pollution in recent years, requires monitoring of the corrosion
behavior of artistic bronzes coated with syntetic patina, in urban atmosphere.
This present work aims to investigate the corrosion rezistance ...
The Corrosion Behaviour of Aluminum Alloy 2024-T3 in Acidic Environments
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
This research aimed at analysing the acidic corrosion behavior of aluminum
alloy 2024-T3 commonly used in the aerospace. We study the variation of corrosion
rate with immersion time at different values of H2SO4 concentration ...
Tribocorrosion-insight Into Material Degradation in Specific Environments
(Universitatea "Dunărea de Jos" din Galați, 2014)
Tribocorrosion is an irreversible surface degradation mechanism of a
metallic and/or non-metallic material as a result of its physicochemical and
mechanical interactions during relative motion (friction, sliding, impact, ...
The Influence of Waste Composition on the Pumping System Corrosion
(Universitatea "Dunărea de Jos" din Galați, 2017)
Wastewater piping systems in urban agglomerations or industrial areas have
problems with the wear and tear of equipment and water transport pipelines used.
The problems are related to hydromechanics wear and corrosion ...
The Chemical and Metallurgical Analysis of Cooper-Based Shape Memory Alloys
(Universitatea "Dunărea de Jos" din Galați, 2015)
The paper presents some aspects on the thermo-mechanical fatigue of shape
memory alloy, a documentary synthesis of their industrial applications and
chemical aspects concerning the use of these alloys in biomedical applications
