Study on Some Copper-Molybdenum Based Composite Materials Condensed from the Vapour Phase
(Universitatea "Dunărea de Jos" din Galați, 2007)
Design features of equipment are given for realizing high-speed process of
electron beam evaporation and condensation. Peculiarities of phase composition
and structure of a crystallized pool (melt) on copper base are ...
Some Results of Researches to Develop the Proper Recycling Methods of Technological Residues from Secondary Aluminum Industry
(Universitatea "Dunărea de Jos" din Galați, 2007)
The objective of the research is to identify new suitable process to use
residual waste (like aluminium secondary dross, salt slag or fly ashes) in concrete
products according with sustainable industry concepts. The paper ...
Study and Researche Regarding Binaring Sistem with TIOBIS - β – NAFTOL
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper presents the results for contribution of determining the manganese
from waters and steel. Manganese, due to its properties, cannot be found but in acid
waters and usually associated with iron. In small amounts, ...
Studies Concerning Energetic Consumption of Some Heating Equipments with Resistors
(Universitatea "Dunărea de Jos" din Galați, 2007)
In order to increase the resistance of aluminium alloys a complex heat
treatment is usually performed. Therefore, we must consider the reaction time
between aluminium alloys and furnace atmosphera. These atmospheres ...
Study of Heat Treatment Influence on Aluminum-Based Alloy ATN-Si10Cu4
(Universitatea "Dunărea de Jos" din Galați, 2007)
This work presents the experimental results concerning the behavior on heat
treatment of on aluminum based alloy. The laboratory level experiments achieved
on samples of ATN-Si10Cu4 (4145 series) alloy illustrate the ...
Hydrogen production by Steam reforming of Renewable Raw Materials
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper is based on study of steam reforming of renewable raw materials
(bioethanol, biomethane) in stainless steel fixed bed reactor. The β-alumina
catalysts with nickel has been synthesized and tested supported. The ...
The Monitoring of Chattering in Cold Rolling Mill System with Stands for Thin Strip
(Universitatea "Dunărea de Jos" din Galați, 2007)
Each system (stand – driving) and the continuous rolling line to which it belongs
have its own functional and energetically parameters. To reduce any faults of the strip
surface it is also necessary to check (eventually ...
Improvement of Steel Sheet Corrosion Resistance by Thermic Coverage Method with Zinc-Aluminium Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the main physico-chemical characteristics (viscosity and
superficial tension of zinc-aluminium liquid alloy in view of carry out protected
layers on steel sheet with very good properties by thermal ...
The Action of the Ultrasonic Vibration Over the Diffusion Process in Gases and Liquids
(Universitatea "Dunărea de Jos" din Galați, 2007)
Among the new method of studying the properties of the substance and the
influence over the most various physical and chemical processes, used in different
industrial domains, the main place is occupied by the usage of ...
Semi-Planetary Rolling and Changes of Fine Structure and Microstructure
(Universitatea "Dunărea de Jos" din Galați, 2007)
The strain intensity in the proximity of planetary cylinder, in the case of semi-planetary
rolling is greater than in the proximity of the massive cylinder. This fact leads at the
variation of the microstructure and fine ...
