Corrosion of Bronze Art Objects and Methods of Restoration
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents a study of the corrosive state of sculptures and art objects
made from copper and bronze, the equipment used to detect and study defects and
the methods and solutions for restoring the art object ...
Behavior of A537 Steel Grade in Carburizing in Fluidized Bed with Endothermic Atmosphere
(Universitatea "Dunărea de Jos" din Galați, 2009)
Fluidized bed allows one to easily change from the chemical composition of the
working atmosphere. The paper is based on experiments of carburizing in fluidized
bed with endothermic atmosphere made from gases resulting ...
Characterization of Iron and Low Alloy Steel Powders Obtain by Water Atomization
(Univerversitatea "Dunărea de Jos" din Galați, 2009)
Three types of iron and low ally steel powders were investigated to
determinate their physical properties and surface morphology by SEM analysis. The
powders were obtained by water atomization. The first type of powder ...
Making Cast Piece Using Exothermic Head
(Universitatea "Dunărea de Jos' din Galați, 2009)
In this paper presents a study about cost of part obtained with exothermal
heads by replacement of classic heads. This method contributes to conduct
solidification of cost pieces, because exothermal heads are forecast ...
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) ...
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 ...
Researches on the Corrosion Behavior for a Drawing Steel That Went Through Natural Ageing
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents the results of a study on the corrosion behaviour of the
sheets of drawing steel with 0,04% C gone through natural ageing and run for a
period of 112 days from the moment of drawing. The researches ...
Optimisation of Refractory Components of Sliding Gate Mechanism for Continuous Casting
(Universitatea "Dunărea de Jos" din Galați, 2009)
New design techniques have been developed to optimize refractory
components of sliding gate mechanism for continuous casting of steel. The overall
objective is to increase CC productivity as well as steel quality by using ...
On the Corrosion Behavior of Organic Nanocomposite Coatings
(Universitatea "Dunarea de Jos" din Galați, 2009)
Recently, researches on composite coatings of organic nature with the addition
of metallic oxide nanopowders have shown an increasing corrosion resistance of
metallic materials. Carbon steel shows an improved behavior ...
Development of Blade Design for Small Hawt Adapted for Lower Values of Wind Speed
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper aims at studing, theoretically and experimentally, the influence of
turbines blade profile on output power, in order to decrease effective domain to
smaller wind speed, specific to Galati area. Studies have ...
