Corrosion Resistance of Zinc Coated Steel in sea Water Environment
(Universitatea "Dunărea de Jos din Galați, 2015)
The life time of metallic materials used in naval transport industry is
influenced by their corrosion resistance. For utilization in shipbuilding and offshore
construction, metallic materials need to be covered with ...
Influence of Secondary Refining Treatments on the Quality of High-Grade Steel Used in Oil and Gas Industry
(Universitatea "Dunărea de Jos" din Galați, 2015)
Steel is the most important alloy used in oil and gas industry from production
and processing to the distribution of refined products. In this research is analyzed
the production technology of steel intended for long ...
Research on the Behaviour of the Tooth-Crown Assemblies Made of Different Metal Materials in Solutiond Simulating the Oral Environment
(Universitatea "Dunărea de Jos" din Galați, 2015)
One of the basic principles of restorative dentistry is the conservation of the
hard dental structure, while satisfying both aesthetic and functional requirements.
Complying with this principle will minimize the harmful ...
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 ...
Alumina Influence on the Corrosion Resistance of Ni-PAl2O3 Composite Layers
(Universitate "Dunărea de Jos" din Galați, 2015)
This paper aims to analyze the corrosion resistance of composite layers based
on Ni-P matrix and disperse phase alumina of 10 μm size, present in amounts of 5,
10 and 20 g / L in the nickel plating bath. The influence ...
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 ...
Corrosion Behavior of Ni-P Coated Steel Strips
(Universitatea "Dunărea de Jos" din Galați, 2015)
In addition to high hardness, Ni-P coatings obtained by the electroless method
are widely used due to their high corrosion resistance. The corrosion resistance
depends on the content of phosphorus in the coating. Various ...
Fuel Consumption Study for Auxiliary Engines that Equip an Oil Tanker
(Universitatea "Dunarea de Jos' din Galați, 2017)
The paper deals with an oil tanker whose propulsion system with internal
combustion engine during navigation was investigated. For a power plant with
internal combustion engines we distinguish the subsystems: the internal ...
Tribolological Behaviour of Nitrocarburized Superficial Layer After Thermo-Magnetic Treatments Applied to Steels, During Friction Process
(Universitatea "Dunărea de Jos" din Galați, 2006)
Two types of steels subjected to a nitrocarburized thermo-chemical treatment
after thermomagnetic treatments. The contact problems are studied employing the
concept of tribosystem and tribomodel. The structural aspects ...
Thermodynamic Assesment of the Ci-Ti System in Microalloyed Copper Base Alloys
(Universitatea "Dunărea de Jos" din Galați, 2006)
The correlations made between thermodynamic and kinetic data of the
heterogeneous systems provided insight into the alloys properties. Experimental
researches presented in this paper refer to the thermodynamics of Cu-Ti ...
