Electromagnetic Strip Mills' Driving Rollers Metallisation Advanced Technics
(Universitatea "Dunărea de Jos" din Galați, 2007)The continuous increase of the applications of thermal sprayed coatings together with the demand for layers having always more and more enhanced performances and properties stimulates the research activity toward ... -
Structural and Tribological Aspects on Ti(C,O,N) Magnetron Reactive Sputtered Thin-Films
(Universitatea "Dunărea de Jos" din Galați, 2007)Magnetron sputtering is a flexible technique and allows producing a significant amount of types of coatings. Within the frame of present work, Ti-C-O-N thin films were deposited onto high-speed steel (AISI M2), substrates ... -
Basic Mathematical Modeling of the Environmental Processes in the Lower Danube Region [I]
(Universitatea "Dunărea de Jos" din Galați, 2007)In most environmental pollution problems, the pollutant is released to the environment by the, almost always, turbulent flow of a carrier fluid. The pollutant mixes with the surrounding fluid (air or water) and undergoes ... -
The Influence of Cold Rolling on the Microstructure for Drawing Steels
(Universitatea "Dunărea de Jos" din Galați, 2007)The paper presents the structural changes that appeared in steel for deep drawing, as a result of cold rolling and of recrystallization thermal treatment. The research was conducted on samples taken from the rolled strap, ... -
Experimental Investigation of Fatigue of Thin-Walled Welded Structures of Commercial Vehicle Frames
(Universitatea "Dunărea de Jos" din Galați, 2007)The fatigue behavior of bus frame components consisting of thin-walled tube beams joined together by fillet welding has been investigated. Numerical analysis by means of finite elements and experimental stress analysis ... -
Mechanical Resistance as a Function of Local Properties
(Universitatea "Dunărea de Jos" din Galați, 2007)The present study makes an estimation of an automotive engine piston mechanical properties and fatigue life based on some characteristics of metallurgical microstructure. Because it is intended to assess the properties ... -
Experimental Research Regarding the evolution of Some parameters of the Superficial Layer in love Cycle Fatigue Process
(Universitatea "Dunărea de Jos" din Galați, 2007)The development of some mechanic engineering systems in, feasible to pressure vessels, aeronautics, ship building technology, requires a full investigation of the material features that are to be examined under a low ... -
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 ...
