Influence of Grease Grade and Working Regime on the Structural Modifications of the Superficial Layers on Roller-Roller Tribosystems
(Universitatea "Dunărea de Jos" din Galaţi, 2007)A X-ray diffractometric method is used for analysing the distributions of the 1-st and 2-nd tension state and dislocation density in the superficial layers, after tests in different working and lubricating conditions, the ... -
On Tribological Behaviour of Thermo-Chemical Treated Steels after Thermo-Magnetic Treatments
(Universitatea ”Dunărea de Jos” din Galați, 2008)The paper presents an analysis on two grades of steel, subjected to nitrocarburized or nitrided thermo-chemical treatment after different thermomagnetic treatments. Based on the concept of tribosystem, pairs of steel rollers ... -
Roughness as Small Surface Defects and Microstructure Changes in the Fatigue Process
(UDJG, 2011)Examinations in detail using X-radiation diffraction of the dislocation substructure in fine-grained S355JR steels plate specimen fatigued with constant amplitude were carried out to investigate the correlation between the ...
