Geopolymers Obtained with Red Mud from Alumina Manufacturing
(Universitatea "Dunărea de Jos" din Galați, 2014)
Getting reusable aluminosilicate materials, based on the geopolymerization
reaction mechanism of some physical and mechanical material particular, has been
imposed in the recent years in building materials.
This paper ...
Silica thin Films Obtaining by Sol-Gel Dip Coating with Controlled Optical Properties
(Universitatea "Dunărea de Jos" din Galați, 2014)
Transparent oxide films are widely employed as antireflection or high
reflection coatings, band-pass filters and narrow-band-filters in various optical and
electronic devices. The performances of these devices are based ...
Aspects of Materials Decay Under Chemical Attack from the Leachate Treatment Plant of the Tirighina Waste Landfill
(Universitatea "Dunărea de Jos" din Galați, 2014)
Human society faces a number of major problems among which the
increasingly negative consequences of environmental pollution. The high uses rate
of the natural resources and the large amount of waste generated tend to ...
Residual Stress and Tribology Behaviour of TiCx Coating Deposited by NPCVD Method
(Universitatea "Dunărea de Jos" din Galați, 2014)
In this paper, thin TiCx films were coated by chemical vapour deposition
method, and various duty cycles were carried out in order to observe the influence
of this parameter on residual stress and tribology behaviours. ...
Corrosion Behavior of Zinc Alloy Layers
(Universitatea "Dunărea de Jos" din Galați, 2014)
The alloying of zinc with some additional elements in specific quantities could
be reliably used in the hot-dip coating process. These elements conferr substantially
improved performance to the end-product specially by ...
Effect of ZnO Nanoparticles on the Anticorrosion Properties of Epoxy Coating
(Universitatea "Dunărea de Jos" din Galați, 2014)
Homogeneous epoxy coating obtained by embedding ZnO nanoparticles (≤50
nm) in the epoxy matrix, was applied on Grade A naval steel substrates by dipcoating
method. The morphology and microstructure of the coatings ...
Research on Abrasive Wear Behaviour of laser Cladding Lyers with Aluminum Bronze Powders
(Universitatea "Dunărea de Jos" din Galați, 2014)
The paper presents the wear behaviour on rotating disk with abrasive paper
of laser cladding layers with aluminum bronze powders compared with steel
samples and aluminum bronze classically quenched. The hardness and wear ...
The Influence of Different Coatings on the Grafhite Degeneration in the Superficial Layer of Iron Castings
(Universitatea "Dunărea de Jos" din Galați, 2014)
The main objective of this experimenal reserch is to investigate new
possibilities for reducing the graphite degeneration phenomenon in the superficial
layer of iron castings.
For the experiment, a spheroidal graphite ...
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 ...
Study Related to improve Performance of a Neutralizing Gas Dynamics System
(Universitatea "Dunărea de Jos" din Galați, 2014)
Worldwide, the series of attacks "with bomb" are the most common,
accounting for over 80% of terrorist attacks. The many constructive solutions of
Improvised Explosive Devices (I.E.D), would require for defusing sequence ...
