Mechano-Erosion: A Novel Test Methodology to Accelerate Erosion in Rolling Contact Fatigue Experiments
(Universitatea "Dunărea de Jos" din Galați, 2008)
Rolling contact fatigue testing of rolling elements with low saturation
temperature lubricants result, in several difficulties. Mainly, uncontrolled phase
changes due to flow dynamics often cause difficulties in assessing ...
Glow Discharge Optical Emission Spectrometry (GDOES), an Effectiveness Method for Characterizing Composition of Surfaces and Coatings
(Universitatea "Dunărea de Jos" din Galați, 2008)
Within the frame of this work, the technical procedures and real advantages of
using Glow Discharge Optical Emission Spectroscopy (GDOES) for establishing
depth concentration profiles of surfaces are presented. GDOES can ...
Steel and Refractory Chemical Interactions and Mechanical Behavior of Plates for Sliding Gate During Steel Continuous Casting
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The main objective to increase CC productivity as well as steel quality by using
optimized refractory from ladle-tundish-to-mold lead to techniques that allow the
prediction of steel and refractory chemical interactions ...
X-Ray Diffraction Study of the Rewverse Martensitic Transformation in Cu-Al-Ni Shape Memory Alloy
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper presents an X ray diffraction study for a cooper based shape memory
alloy. The behavior of CuAl13Ni4 alloy, which exhibits a peculiar property, is
evaluated by structural changes. On cooling, the martensitic ...
Half-Finished Technology of Steels and Fatigue Strength
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents the bending fatigue testing for four steel brands. The test
showed that the fatigue strength is decreasing with the increasing of both ingot size
and the rolled sheet thickness. The fatigue strength ...
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, ...
Nanostructured Surface for 38MoCrA109 Steel by Nitriding in Nitrogen Atmosphere and Yag;Nd Pulse Laser Activation
(Universitatea "Dunărea de Jos" din Galați, 2008)
YAG:Nd pulse laser is usually used for cutting and welding. The paper is based
by experiments using YAG:Nd pulse laser (KVANT 17-CIS made). Technological
modules were assembled for laser beam deviation and for relative ...
Modelling by Finite Element Analysis Method of Stress State Establishing for an Alloy Steel
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents some results about the tension state in samples subject to
pure bending fatigue process. Numerical simulation based on finite element method
was used. The tension field induced by a vertical deformation ...
Electrodeposition Obtaining and Corrosion Behaviour of Phenol Formaldehyde Resin/Zinc Composite Coatings
(Universitatea "Dunărea de Jos" din Galați, 2008)
The present work has the purpose of obtaining composite coatings in zinc matrix
by using phenol - formaldehyde resin type NOVOLAC (RESITAL 6358/1) in the
electrodeposition process of zinc. The PF resin/Zn composite ...
Laser Surface Alloying of Some Steels from SiC Predeposited Powders
(Universitatea "Dunărea de Jos" din Galați, 2008)
For the purpose of studying the possibilities of increasing the wear resistance,
specimens of three steels with 0.2%C, 0.46%C and 1%C were surface alloyed with
reinforcement from overlapping pastes with green SiC hard ...
