Possibilities to Evaluate the Value of the Marangoni Effect and of the Marangoni number in Refining Steel-Slag/Inclusion Systems
(Universitatea "Dunărea de Jos" din Galați, 2006)
Starting from the impressive progress in studying the instabilities induced by
capillary effects in systems of two immiscible fluids in chemistry, an analysis of factors
in solutal Marangoni effect and Marangoni number ...
Behavior of Some Stainless Nitrided Austenite Steel Types to Corrosion and Abrasion
(Universitatea "Dunărea de Jos" din Galați, 2006)
By nitriding, stainless austenite steel types can become surface hardened. Hardness
can be greater at more than 1000 HV005 when the composition layer made of complex
nitrides is obtained and more reduced till 500 HV005 ...
The Decreasing of the Energetic Losses at a Coke Cooling Plant
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper presents an energetic and technologic analysis of the metallurgic coke
dry cooling plant (CDCPO) operating, and also the optimization of this process in
the case of an industrial plant, existing in the Steel ...
Kinetic of Martensite Transformation in a Cu-13wt. %Al-4 wt.%Ni Shape Memory Alloy
(Universitatea "Dunărea de Jos" din Galați, 2006)
In this paper we present some results was obtained on the Cu-13wt. %Al-4 wt.
%Ni shape memory alloy. This alloy was elaborated by a classic melting method
starting at pure metals. A DSC analysis was made for quenched ...
Some Issues Concerning Gear Wheels Fabrication by Sintering
(Universitatea "Dunărea de Jos" din Galați, 2006)
Powder metallurgy appeared in the XVIII century as result of industrial market
demand for electric bulbs filaments made of wolfram. Nowadays powder metallurgy
is applied in such fields as: automotive industry (cylindrical ...
Air Quality Monitoring in Galați. Case Study
(Universitatea "Dunărea de Jos" din Galați, 2006)
This paper presents information referring to the variation of aerosols
concentration in a central area in Galati. For a period of time of november2005 to
november 2006, there have been made correlations between aerosols ...
Behavior of 1%Cr Steels at Fluidized Bed Nitrocarburizing
(Universitatea "Dunărea de Jos" din Galați, 2006)
Paper is based by nitrocarburizing experiments made on laboratory plant. For
experiments were used different samples of steel at different nitrocarburizing
regimes. Influence factors were: temperature and ammonia ...
Hardened Aluminium with Discontinuous Copper Threads
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper presents the influence of the quantity of discontinuous reinforced
threads on the mechanical characteristics of some samples obtained through
deformation from composite material with metallic matrix.
As a raw ...
Behavior of Welded Joints from Some Stainless Austenite Steel Eypes During Nitriding Process
(Universitatea "Dunărea de Jos" din Galați, 2006)
Researches made on welded and nitrided samples from stainless austenite steel
types show that nitriding thermo chemical treatment can be applied also for
welded joints. As a result of the treatment, a diffusion layer ...
Tribolological Behaviour of Nitrocarburized Superficial Layer After Thermo-Magnetic Treatments Applied to Steels, During Friction Process
(Universitatea "Dunărea de Jos" din Galați, 2006)
Two types of steels subjected to a nitrocarburized thermo-chemical treatment
after thermomagnetic treatments. The contact problems are studied employing the
concept of tribosystem and tribomodel. The structural aspects ...
