Studies and Research Obtaining Bronze Filters Using Powder Metallurgy Methods
(Universitatea "Dunărea de Jos" din Galați, 2015)
The article presents how to obtain porous bronze products using copper -
based powder by powder metallurgy methods. The formation of tablets was done by
free pouring the spherical powder into the mould, followed by their ...
Evaluated Work System and Environmental Risk for a Worker in Drilling for Methane Gas
(Universitatea "Dunarea de Jos" din Galați, 2015)
Improving the safety and health at work is important not only in terms of
human view, in order to reduce possibilities of accident to workers, but also as a
way to ensure the success and durability work for a worker in ...
The Influence of the Steel's Surface Quality on the Electroless Ni-P Coatings
(Universitatea "Dunărea de Jos" din Galaţi, 2015)
The method of autocatalytic reduction coating assures a precise reproduction
of the coated surface. This is an advantage when the support surface has a complex
geometry but also becomes a disadvantage because it requires ...
Research on the Corrosion Resistance, in Saline Solution, of Steel Sheets for Industrial Construction, by Gravimetric Method
(Universitatea "Dunărea de Jos' din Galați, 2015)
In this paper, it was presented a study on corrosion in saline medium, by
gravimetric method, of the steel sheets for industrial construction. The corrosion
rate was estimated by gravimetric method and evaluate based on ...
Corrosion Behaviour and Biocompatibility of 316 Stainless Steel as Biomaterial in Physiological Environment
(Universitatea "Dunărea de Jos" din Galați, 2015)
Although stainless steel is a material widely used for biomedical applications,
its surface properties for long term application are still a serious concern. 316L
stainless steel (SS 316L) is a material commonly used in ...
Surfasce Roughness and Topography of Ni/Micro-Sic Layers: Influence of Current Density on Electrodeposition Process
(Universitatea "Dunărea de Jos" din Galați, 2015)
The surface properties are directly responsible for the performance of
engineering materials because most of failures such as friction, wear, corrosion
and fatigue often take place on the material surface. Electrodeposition ...
Treatment of Ammonia Wastewater by Ultrasound. Part I: The Influence of the Ultrasound energy on the ultrasound Bath Temperature
(Universitatea "Dunărea de Jos" din Galați, 2015)
The industrial ammonia water decontamination depending on the sample
temperature is monitored by this study. The treatment was conducted by the
UP100S ultrasound generator (Hielscher Ultrasound Technology, Germany),
operating ...
Laser Deposition of Bronze Aluminum on Steel Support
(Universitatea "Dunărea de Jos" din Galați, 2015)
In order to rise the wear and corrosion resistance of 0.45% C superficial steel
layers, a multilayer coating was tested by injection of powder with 88.3% Cu; 9.5%
Al; 2.2% Fe in melted bath by CO2 continuous wave laser. ...
Optimization of Thermal Processing Parameters of a High Strength Aluminum Alloy
(Universitatea "Dunărea de Jos" din Galați, 2015)
The work shows a calculation meant to optimize the thermal processing
parameters (time and temperature) of a high strength aluminum alloy. The
optimization calculation has been done by gradient method which involves ...
Urban Pollution Issues Generated by Trams Traffic
(Universitatea "Dunărea de Jos" din Galați, 2015)
The modern society development involves new and diverse issues considering
urban environmental pollution. Traffic generated sound and vibration are two upto-
date urban environmental pollution causes besides air and water ...
