A Study of Electromagnetic properties of Fiber Fabric Based Filled Epoxy Composites
(Universitatea "Dunărea de Jos" din Galați, 2007)
Electric and magnetic properties of laminate carbon fiber fabric based epoxy
composites are investigated through experimental techniques. Various
concentrations of powder fillers were used in order to change the basic ...
Vibration Diagnosis Systems for a Cold Rolling Mill Machine
(Universitatea "Dunărea de Jos" din Galați, 2007)
In this work is shown the importance to use a monitoring by vibration system
for a cold rolling mill machine. The using of this monitoring vibration system reduce
maintenance costs, minimize the impact on operation because ...
Granularly unbind Materials for Casting Composite Moulds
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper present some partial result based on this idea (of pollution
prevention) the domain of making composite-casting moulds (in time of casting,
solidifying, and alloy cooling). Casting process impose temporary or ...
Reduction Rate of Remanent Stress in Thermal Spraying Depositions by Shot Peening
(Universitatea "Dunărea de Jos" din Galați, 2007)
Thermal electric-arc spraying coatings are widely utilized both to get new
parts ant to repair the used ones. Just like with the other thermal spraying
procedures, the other thermal spraying procedures, the thickness of ...
X-Ray Diffraction Residual Stress Measurements for Quality Control Testing
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper present the primary difficulties which are associated with the
obtaining and interpreting surface X-ray diffraction residual stress results: the
surface stresses may be identical for the shoot peening, nitriding ...
New Welding Techology-The Cold Welding on Cogged Surfaces
(Universitatea "Dunărea de Jos" din Galați, 2007)
Welding by cold pressing on cogged surfaces, produces the joint of a
component made from an easy deformable metal by pressing on the cogged surface
of a harder metal component. Different welds between aluminium (the ...
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 ...
Modelling and Prediction in Failure Processes by Mechanical Stresses in Corrosive Environment
(Universitatea "Dunărea de Jos" din Galați, 2007)
The complex interaction effect of mechanical stress- mechanical systems and
aggressive environment, leads, at dramatic decreasing of their durability and
reliability. The analyze of physical-chemical processes such as: ...
Recycling Possibilities of Metallurgical Slag
(Universitatea "Dunărea de Jos" din Galați, 2007)
The target of the current metallurgical industry is to recycle and utilize all their
by-products. Slags are the important wastes and by-products of metallurgical
industry, which have been treated, recycled and used ...
