Alumina Powder Properties Obtained by Neutralization Process of Sodium Aluminate
(Universitatea "Dunarea de Jos' din Galați, 2009)
Today, the most production of alumina is used for aluminum production [1, 2]
(metallurgy alumina), minor production of alumina is used for special purpose, as
fire-resistant materials, electro porcelain and etc., and ...
Mathematical Model Cooling Agglomeration Ferrius in Layer
(Universitatea "Dunărea de Jos" din Galați, 2009)
Mathematical model is based on discretization agglomeration areas layer
deposited on very small. The τ Δ cooling time and the elements of space and
elements xi time relationship is discretization as volume control. Based ...
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 ...
Experimental Research Regarding the Obtaining of Obtaining of Friction Elements
(Universitatea "Dunărea de Jos" din Galați, 2009)
Friction materials are used as bimetallic friction elements, consisting of a
friction material layer sintered on a steel backing. Using the electron microscopy
techniques (microprobe analyzer) some of the diffusion ...
Materials Used for Manufacturing Some Objects from 1600 Before Christ - 500 After Christ Period
(Universitatea "Dunărea de Jos" din Galați, 2010)
The appearance and the spreading of metallic objects produced a profound
social change. The early metallurgy included two ages: The Bronze Age and The
Iron Age. The late Bronze Age is considered to be the most important ...
Theoretical Study regargind the Flow Conditions for Alloys Through thin Channels
(Universitatea "Dunărea de Jos" din Galați, 2010)
A common tool used to demonstrate the phenomenon of movement of liquids
through thin channels is the capillary tube. When the lower end of the tube is placed
vertically in a liquid (such as water), it forms a concave ...
Experimental Model for Pollutants Monitoring Into the Coke-Chemical Plant
(Universitatea "Dunărea de Jos' din Galați, 2009)
The Coke-Chemical plants contribute heavily to producing and emitting in the
atmosphere a big amount of polluting agents.
Polluting emissions diminution and situating them within the international
specific standards, ...
Electrodeposition and Characterization of Zinc-Cobalt Alloy Coatings
(Universitatea "Dunărea de Jos" din Galați, 2010)
Electrodeposited alloys are important in industry due to their properties which
are superior to those of single metal layer. Zinc-cobalt alloys were co-deposited on
gold substrate. Composition of the layers was established ...
Intercritical Thermomechanical Treatments Applied to the Steel Heavy Plates
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paperwork shows the laboratory experiments made on X60 and X65 steels
with several intercritical thermomechanical treatment applications. Two variants
were used: "down-up" thermomechanical treatment with heating and ...
The Process Insolved in Making the Medals
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper presents a method that was experienced in the laboratory to
manufacture a medal. There are three general techniques used to make medals:
repoussé, striking and casting. Serigraphy technique is the most chosen ...
