Study of the RV52 Steel Plates Properties After Thermic Treatment
(Universitatea "Dunărea de Jos" din Galați, 2009)
The thermal treatment of RV52 steel plates determines high mechanical
properties such as: strength, wear resistance and tenacity. The normalized plate
samples were studied to determine the effect of the tension release ...
The Steam-Secondary Source of Energy in Metallurgy
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper is focused on a study of how to use the steam from recovery boilers
of LD converters to produce electricity in turbine generators and heat in a heat
network.
Study of Tribocorrosion Processes by Electrochemical Techniques
(Universitatea "Dunărea de Jos" din Galați, 2007)
Tribocorrosion is defined as the chemical-electrochemical-mechanical process
leading to a degradation of materials in sliding, rolling or erosion contacts immersed
in a corrosive environment. That degradation results ...
Study on the Specific Effects of Corrosion processes on Ancient Bronze Artefacts
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the cases of the corrosion processes which take place on
starting from the usage period when the primary patina is being formed and when
the secondary patina starts, than continuing with the archaeological ...
