Study of the Sintering Process of Iron Powders Coated with Nano-Hydrocarbon and the Resulting Microstructure at Temperatures up to 1200°C
(Universitatea "Dunărea de Jos" din Galați, 2009)
The objective of the research is development and study of a new ecologically
friendly and technologically advanced method for introduction of carbon during
sintering of low alloyed iron powders ASC 100.29. The method is ...
The Influence of Cold Rolling on the Microstructure for Drawing Steels
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the structural changes that appeared in steel for deep
drawing, as a result of cold rolling and of recrystallization thermal treatment. The
research was conducted on samples taken from the rolled strap, ...
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 ...
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 ...
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 ...
Microstructural Characteristics of Sintered Powder Metallurgy Alloys
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
The purpose of this paper is to study the influence of processing parameters
on the microstructural characteristics of sintered powder metallurgy alloys. The
specimens were produced from atomised iron powders with different ...
Modification of Surface Properties by Laser Cladding with Ni-Cr-B-Fe-Al Alloy
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The paper is focused on modification of surfaces properties by laser cladding.
To follow the corrosion behavior in different media of laser cladding layers made of
nickel based alloy Ni - Cr - B - Fe - Al. It was studied ...
Ni-P Coating on Steel Support by Electroless Method
(Universitatea "Dunărea de Jos" din Galați, 2017)
The autocatalytic reduction method (electroless method) was applied to obtain
the Ni-P layers with different P contents. Nickel sulfate was used as nickel ion
source and as reducing agent the sodium hypophosphite. The ...
Physical-Mechanical and Technological Characteristics of Ti10Zr Alloy for Dental Applications
(Universitatea "Dunărea de Jos" din Galați, 2016)
Progress reported over time in dentistry can be attributed largely to the
dynamics of acquiring new materials. A biomaterial is considered ideal in the
absence of any biomaterial-tissue interaction, which means a biomaterial ...
