Tribological Aspects of Electrode-Elastomer Contact
(UDJG, 2010)Dielectric elastomers (DE) are soft polymers based smart materials that may be potentially employed in applications such as actuation, sensing and energy harvesting. The performance of dielectric elastomer actuators (DEA) ... -
Tribological Behaviour of Molybdenum Disulphide Nanoparticles
(Universitatea ”Dunărea de Jos” din Galați, 2009)l dichalcogenides, are well known for their solid lubricating behaviour. Thin films of MoS2 exhibit extremely low coefficient of friction in dry environments, and are typically applied by mixing in oil, grease or impregnated ... -
Tribological Behaviour of CO-CR-MO and Uhmwpe the Components of Intervertebral Disc Prosthesis
(Universitatea ”Dunărea de Jos” din Galați, 2006)The Intervertebral Disc Prostheses consist of a modular system and his function is based on low intervertebral friction. As a result of friction forces acting to the spine structures, the intervetebral disc prostheses can ... -
Tribological Behaviour of Nitrocarburized Steels After Thermo-Magnetic Treatments
(Universitatea "Dunărea de Jos" din Galaţi, 2008)Two types of steels were subjected to a nitro-carburized thermo-chemical treatment after thermo-magnetic treatments. The structural aspects into the superficial layer of these steels are studied during the friction process ... -
Tribological Characteristics and Formation of Subsurface Structures of Cast FE-CR-C Alloys with Different Content of Copper, under Sliding Friction
(Universitatea ”Dunărea de Jos” din Galați, 2009)Effect of copper contents (0%, 0.4%, and 14%) and modes of heat treatment on initial structure of Fe-Cr-C alloys (C~1.2%, Cr = 17…19%) and subsurface structure of friction layers and tribological characteristics of these ... -
Tribological Studies Regarding the Crude Rapeseed Oil Press
(Universitatea "Dunărea de Jos" din Galați, 2016)The aim of this paper is to present a tribology test conducted on crude rapeseed oil press. The experiments were carried out with four-ball machine. The oil was tested at speed of 1000 rot/min and loads of 140 N and 200 ... -
Tribological Testing Programs for Uhmwpe Matrix Composites
(Universitatea ”Dunărea de Jos” din Galați, 2009)This paper aims to review the knowledge on materials and tribology of the ultra high molecular weight polyethylene (UHMWPE) composites. The various mechanisms proposed for the wear behaviour of UHMWPE are closely associated ... -
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 ... -
Trilemma EU and EMU Challenges: Fiscal Competition, Harmonization or Unification
(“Dunarea de Jos” University of Galati, 2014)Eurozone has grouped 18 countries in the European area, with different tax systems and thus, on the background of a common monetary policy numerous decisions and commitments for fiscal harmonization were adopted. ... -
