Structural Characteristics in Cobalt Based Alloys
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
In the present paper there are presented results of investigations on samples of
partially removable denture made of cobalt base alloys (Co-Cr-Mo) regarding
specific structural analysis: determination of structural phases ...
Characterization of Thick Hard Layers with ni-Cr-B-Fe-Al Alloy Obtained by Laser Cladding
(Universitatea "Dunărea de Jos" din Galați, 2009)
To increase the resistance to wear and corrosion of the surface layers made
from steel with 0.45% C, multilayer deposition was tested by injection of powder
with chemical composition of 8.9% Cr, 4.5% Fe, 5.1% B, 2, 4% ...
EDX Analysis of Laser Cladding Layers with Ni-Cr-B-Fe-Al Alloy
(Universitatea "Dunărea de Jos" din Galați, 2009)
Multilayer cladding by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B,
2.4% Al, 0.6% Cu, Ni rest as chemical composition, in melted bath by a continuous
wave CO2laser connected to x-y-z coordinate table was tested in ...
Resesrches on the Production of Copper-Based Composites by Powder Metallurgy Methods
(Universitatea "Dunărea de Jos" din Galați, 2014)
The article presents how to obtain copper matrix composite with alloy
particles of NiCrBFeAl as complementary phase. The samples were obtained by
powder metallurgy methods using different percentages of the additional ...
Structuras of the Eutectoid Zn-Al Alloy Obtained by Directed Solidification
(Universitatea "Dunărea de Jos" din Galați, 2014)
This work analyses the structure of the eutectoid Zn-Al based alloy
directionally solidified, with cooling rates ranging between 8.5-0.4 oC/sec. During
cooling, the temperature gradient in the liquidus zone, respectively ...
Research on the Influence of the Complementary Phase Percentange on the Properties of Copper-Based Composites
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
The article presents the method to obtain copper matrix composite with Cu-
Al-Fe alloy particles as complementary phase. The samples were obtained by
powder metallurgy methods using different percentages of complementary ...
The Protective Behaviour Titanium Nitride Coatings
(Universitatea "Dunărea de Jos" din Galați, 2015)
The experiments conducted to obtain a thin layer of nitride through the
vapour chemical deposition method have followed an original path to obtain TiN
directly in the working room thus avoiding the import of these ...
Studies and Researches Regarding the Obtaining and Characterization of Composite Nickel Coatings-Ni/Al2O3, Ni/Kaolin Electrochemically Produced
(Universitatea "Dunărea de Jos" din Galați, 2016)
This study presents the composite nickel coatings electrochemically obtained
using as disperse phases Al2O3 particles and kaolin. There were used Watts
electrolytes, with a pH = 4, current density of 4 A/dm2, a concentration ...
Studies and Research Obtaining Bronze Filters Using Powder Metallurgy Methods
(Universitatea "Dunărea de Jos" din Galați, 2015)
The article presents how to obtain porous bronze products using copper -
based powder by powder metallurgy methods. The formation of tablets was done by
free pouring the spherical powder into the mould, followed by their ...
Laser Deposition of Bronze Aluminum on Steel Support
(Universitatea "Dunărea de Jos" din Galați, 2015)
In order to rise the wear and corrosion resistance of 0.45% C superficial steel
layers, a multilayer coating was tested by injection of powder with 88.3% Cu; 9.5%
Al; 2.2% Fe in melted bath by CO2 continuous wave laser. ...
