Some Aspects Regarding the Elaboration of Multiple precessional Gear Theory and Modern Manufacturing Technology
(Universitatea "Dunărea de Jos" din Galați, 2006)
The engineering complex study of the triad “gear-technology-transmission” has
permitted to elaborate a new type of precessional transmissions with multicouple
gear. In this paper, the authors present the mathematic model ...
Protective and Decorative Vacuum's Coatings on Wares of Artistic Castings
(Universitatea "Dunărea de Jos" din Galați, 2006)
The problem of environmental protection is extraordinarily important, and its
actuality will increase with every year. In this aspect, processes of depositing of
coatings in vacuum have got serious advantages before ...
Research About the Vibration Parameters for a Cold Rolling Mill Machine
(Universitatea "Dunărea de Jos" din Galați, 2006)
By using the equipments of vibration measurement we can fight against the
damages (strip undulation and thickness variation on the length) who is show in
while of mill work. The amplitude of vibration parameters determine ...
Surface Hardening of 40Cr10 steel After Short Time Nitriding in Fluidized Bed
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper is based by nitriding in fluidized bed experiments over laboratory
plant. Fluidization applications are characterized by high values of mass and heat
transfer coefficients. For experiments were used 40Cr10 ...
Oxidizing Influence Over Surface Structures and Properties for A3k Steel Nitrocarburized in Fluidized Bed
(Universitatea 'Dunărea de Jos" din Galați, 2006)
Surface duplex thermochemical treatment (oxinitrocarburizing) has principal
scope to obtaining superficial mechanical higher properties with increasing
corrosion capacity. The paper is based by oxinitrocarburizing ...
Experimental Equation of Deformation Behaviour of a Concrete Steel
(Universitatea "Dunărea de Jos" din Galați, 2006)
The plastic deformation behavior is defined by the function of the deformation
strength according to the strain, strain rate and temperature as the factor of the
deformation process. The behavior law establishes by the ...
