Obtaining and Characterizing TIN-LEAD Coatings on Steel Band
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The experimental research was at the basis of the hot immersion coating
technology with Sn-Pb alloy of the steel bands presented in the study. The
characterization of these layers was achieved through microscopic analyses ...
A test for Rapid Tribological Characterization of Bearing Steels
(Universitatea "Dunărea de Jos" din Galați, 2012)
In this paper is a study the influence of the material and heat treatment on the
changes of the fine structure parameters of the superficial layer of triboelements
during the first cycles of rolling contact process. The ...
Composition of Syngas Produced by Gasification of Agricultural Residue Briquettes
(Univesitatea "Dunărea de Jos" din Galaţi, 2012)
This paper summarizes the results of an experimental study on the gasification
of briquettes made from different agricultural residues. There were investigated the
effects of operating parameters such as temperature and ...
Modern approaches in Design Optimization of Parts and the Development Trend of Surface Treatments
(Universitatea 'Dunărea de Jos"din Galați, 2012)
This paper summarizes the surface engineering technologies having a
substantial contribution to increasing operational performance of the parts as well
as current trends in the implementation of surface processing ...
Microstructural Evolution of al 1100 Aluminum Subjected to Severe Plastic Deformation
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The goal of this document is to promote a sequence of bulk-deformation
processes able to produce ultrafine grain and also nanostructured wires with
adequate length to be interesting for processing in metallurgical industry. ...
Performance Management System for purifyng Polluted Industrial Water
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
In this paper we show an integrate system of water management and an
efficient solution that is a floating dock, placed in the harbour area. Water quality
is one of the most important elements for life support and ...
Properties of Slags in the System CaO-MgO-Al2O3-SiO2, Important in Deoxidization and Desulphurization of Low Carbon Aluminium Killed Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
Properties of refing slags belonging to the system CaO-MgO-Al2O3-SiO2 are
important in simultaneous or succesive refinig treatment processes in the ladle and
other refing metalurgical reactors. The efficiency of treatments ...
Increase the Steels Purity cast in Vacuum
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The need to develop products with special characteristics and high
mechanical properties led to the introduction of plastic deformation of semifinished
materials. Special purpose products are produced from slabs, ...
Selective Growth of 1D Nanostructured Oxide Materials Using PDMS Stamp
(Universitatea "Dunărea de Jos" din Galați, 2012)
The approach for selective growth of 1D nanostructured oxide materials using
poly (dimethylsiloxane) (PDMS) stamp consists of using microcontact printing, as
such the soft lithography technique, for transferring the ...
The Influence of Steam Treatment on Mechanical Properties and Abrasive Wear Behavior of Sintered P/M Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
In this paper is a study of the influence of steam treatment on sintered P/M
steels, for three different types of powder. The abrasive wear of steam-treated
sintered iron is analysed by abrasion tests. The specimens were ...
