(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 ... -
Behavior of A537 Steel Grade in Carburizing in Fluidized Bed with Endothermic Atmosphere
(Universitatea "Dunărea de Jos" din Galați, 2009)Fluidized bed allows one to easily change from the chemical composition of the working atmosphere. The paper is based on experiments of carburizing in fluidized bed with endothermic atmosphere made from gases resulting ... -
The Behavior Of Asymmetric Frontal Couplings With Permanent Magnets In Magnetic Powder And High Temperature Environments
("Dunarea de Jos" University of Galati, 2002)The main purpose of this paper is the comparative analysis of the behavior of frontal couplings with Nd-Fe-B permanent magnets in difficult environments, specific to metallurgy – such as environments with magnetic powders ... -
Behavior of Cold Rolling Emulsions in the Obtaining Process of Steel Strips
(Universitatea "Dunărea de Jos" din Galați, 2014)The research was focused on determining an optimum rolling emulsion to be used on a cold rolling mill from Galfinband Galati Romania. In this plant are obtained steel strips with the thickness of 0.7-0.8 mm. The main ... -
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 ... -
Behavior of Refractories in Interaction with Metallurgical Slag
(Universitatea "Dunărea de Jos" din Galați, 2012)The aim of this paper is to present the studies concerning behavior of the refractory to metallurgical slag corrosion. The corrosion resistance at high temperatures using the static method on samples containing chamotte ... -
Behavior of Rp3-High Spped on Short Time Nitriding in Fluidized Bed
(Universitatea "Dunărea de Jos" din Galați, 2005)For steel nitriding, treatment time is a important factor. Gas and plasma nitriding are usual method to increase surface properties by nitriding. A close retort is used. Total time for treatment are higher because are ... -
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 ... -
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 ... -
A Behavioral Approaach for Competitive Business Process Management
(Universitatea "Dunărea de Jos" din Galați, 2010)Today’s economic context allows corporations and their business environment to produce larger and larger amounts of data relying on the latest information. For the survival in actual complex and unpredictable environment, ... -
Behaviour at Nitriding in Fluidized Layer of Austenitic Stainless Steels at the Temperature
(Universitatea "Dunărea de Jos" din Galați, 2007)Nitriding at low temperatures, 450-500oC of austenic stainless steels lead to the obtaining of the tough layers over 1000 HV005 but having thicknesses of tenths of microns. Moreover, nitriding at 500ºC has determined the ... -
Behaviour at Nitriding in Fluidized Layer of Austenitic Stainless Steels at the Temperature of 450°C
(Universitatea "Dunărea de Jos" din Galați, 2007)Stainless austenitic steels have a good corrosion resistance but reduced abrasion strength due to low strength below 200HV5. By nitriding one may ensure the obtaining of a superficial layer with increased strength that ... -
Behaviour of a Hydrodynamic Journal Bearing: Torque Measurement During Start-Up
(Universitatea ”Dunărea de Jos” din Galați, 2008)The start-up friction coefficient in hydrodynamic bearings, used by engineers in the design of bearings, is most often issued from an approximation. Several studies can be found in the literature on this topic but most of ... -
Behaviour of Some Important Components in a cold Rolling Mill
(Universitatea "Dunărea de Jos" din Galaţi, 2008)For a good behaviour of mill parts and accurate functioning it is necessary to have an integrated system for all mill tandem. It is important to know the speed controls and strip tension in correlation with torque, ... -
Behaviour of the Mobile Phones Owners Relating to the Management of Theyr Devices
(Universitatea "Dunărea de Jos" din Galați, 2015)Today mobile phones have become apparently indispensable. They are the most used electronic devices in the world. The useful life of a mobile handset is decreasing; life cycle is diminished as a result of the speed of ... -
Bending of Thin Walled Pipes Using the Heat Realised by Friction
(Universitatea ”Dunărea de Jos” din Galați, 2006)This paper considers appliance of heat generated by friction to relieve deformation of light metals, having as example of bending thin walled copper pipes. Based on numerous, primarily experiment analysis the conclusions ... -
