Influence of Alloying Elements on Corrosion Resistance of Some Iron - based Sintered P/M Alloys
(Universitatea "Dunărea de Jos" din Galați, 2015)
In this paper is described the influence of alloying elements on corrosion
behavior of sintered iron parts. The compacts were sintered at 1,150 °C and the
sintering time was 60 minutes. After microstructural studies, the ...
Wear Behavior of Carburizing on Powder Metallurgy Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)
In this paper is studied the influence of wear behavior of carburizing in
fluidized-bed on sintered alloys produced by powder metallurgy route. In powder
metallurgy, carburization is a thermochemically treatment that ...
Hardened Aluminum with Oxide Particles
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper presents the effect of size and dispersion degree of the particles of
aluminum oxide, on structure, mechanical characteristics and phenomena that take
place when heating at different temperatures for ...
Dimensional Changes in Some Iron-Based Powder Metallurgy Alloys
(Universitatea "Dunărea de Jos" din Galați, 2015)
The purpose of this paper is to present the dimensional changes in some ironbased
(P/M) alloys. The specimens produced from atomized iron powder and
alloyed powder with different sizes (< 45, 45-63, 63-100, 100-150, >150 ...
Corrosion Behavior of Some Materials in 0.5 M Ammonium hydroxide Solution
(Universitatea "Dunărea de Jos" din Galați, 2013)
The present work has the purpose of studying metallographic aspects and
corrosion resistance of three materials used in ammonia stripping plants. The
corrosion process was evaluated by gravimetric tests and potentiodynamic ...
Composite-Decorative Tiles with Granite
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper presents the results of the authors’ scientific research on a composite
material with polymeric matrix, hardened with rock particles. It was studied the
influence of the quantity of the hardening phase on the ...
Elastoplastic Model for the Steel Bars Under Thermal Treatments
(Universitatea "Dunarea de Jos" din Galați, 2005)
In order to understand material behavior, during the stresses action produced
by thermal effects of volume, was started from Hooke relations, whereat was added
the expressions that take into account these effects. Have ...
Choosing and Using Rationally the Thermic Processed Steels
(Universitatea "Dunărea de Jos" din Galați, 2012)
On a global scale one can notice a constant preoccupation for a rational
choosing and using of the materials on the whole and, especially of the steels with
the main objective the increase of the machines’, equipment’ ...
The Properties of Hardened Lead
(Universitatea "Dunărea de Jos" din Galați, 2005)
Lead hardened through oxide scattering is investigated as raw materials for the
fabrication of the support gratings of lead accumulators in order to increase their
life service. For the preparation of lead powder hardened ...
