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 ...
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 ...
The Different Practical Application of Niobium Carbide Coatings Elaborated by CVD Process
(Universitatea "Dunărea de Jos" din Galați, 2016)
In this paper, the different application of niobium carbide coatings onto hard
carbide substrate was investigated using scanning electron microscope (SEM), Xray
diffractometer (XRD) and micro-hardness. The paper conducted ...
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 ...
The Influence of the Carbon Content on the Depth of the Carbonitrurat Layer in Fluidized Layer for 1C15, 1C25 and 1C45 Steels
(Universitatea "Dunărea de Jos' din Galați, 2016)
This paper presents the experimental research of carbonitriding
thermochemical processing in fluidized layer performed on some samples of carbon
steel with different carbon contents, the fluidized layer being made up of ...
