Analytical Methods Helping the Archaeologists: Archaeometry
(Universitatea "Dunărea de Jos" din Galați, 2009)
Very important objects of cultural heritage are material objects and objects of
art produced by all communities. The physical and mechanical properties of
material culture are always of prime concern to archaeometry and ...
Quality Engineering Procedures Applied to Determine the Weight of Influence of Factors on Microtrigeneration Systems (mCCHP)
(Universitatea "Dunărea de Jos" din Galați, 2009)
Microtrigeneration systems are characterized by simultaneous generation of
power, heat and cold for small applications (<50kW) and are designed for reducing
GHG and other emission degreases. The cooling generation by ...
A Typical Surface Formations Found on the Corrosion Layer of Iron Artefacts
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents the experimental results obtained by applying non-invasive
methods (OM, SEM-EDX, XRF) on two iron artefacts from the IInd and the IIIrd
centuries A.D. (discovered in the incineration graves from ...
Superior Valorisation of the Aluminium Scraps for Obtaining Complex Aluminium Master Alloys Used in Advanced Refining of the Steels
(Universitatea "Dunărea de Jos" din Galați, 2009)
The research about aluminium scraps valorisation to obtain master alloys with
reactive elements (Al, Mn, Si) used for special steels refining is presented in this
paper. By this way the recycling of aluminium scraps leads ...
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 ...
Physical-Chemical Properties (Cu-Sn) -Mo Composite Materials
(Universitatea "Dunărea de Jos" din Galați, 2009)
The article is devoted to the study of corrosive and thermal stability of
materials composition on the basis of copper, obtained by the EB-PVD method.
It is shown in this work that corrosion of (Cu-Sn)–Mo composites have ...
Characterization of Thick Hard Layers with ni-Cr-B-Fe-Al Alloy Obtained by Laser Cladding
(Universitatea "Dunărea de Jos" din Galați, 2009)
To increase the resistance to wear and corrosion of the surface layers made
from steel with 0.45% C, multilayer deposition was tested by injection of powder
with chemical composition of 8.9% Cr, 4.5% Fe, 5.1% B, 2, 4% ...
