Behaviour at Nitriding in Fluidized Layer of Austenitic Stainless Steels at the Temperature of 450°C
(Universitatea "Dunărea de Jos" din Galați, 2007)
Stainless austenitic steels have a good corrosion resistance but reduced
abrasion strength due to low strength below 200HV5. By nitriding one may ensure
the obtaining of a superficial layer with increased strength that ...
Improvement of Steel Sheet Corrosion Resistance by Thermic Coverage Method with Zinc-Aluminium Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the main physico-chemical characteristics (viscosity and
superficial tension of zinc-aluminium liquid alloy in view of carry out protected
layers on steel sheet with very good properties by thermal ...
XRD Analysis in Front of a Corrosion Crack Tip
(Universitatea "Dunărea de Jos" din Galați, 2008)
During exploitation of the heat exchangers some damages can appear in the
contact region between the gaskets and the stainless steel walls. The studies upon
the material were performed using SEM microscopy, X-ray ...
Corrosion of Bronze Art Objects and Methods of Restoration
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents a study of the corrosive state of sculptures and art objects
made from copper and bronze, the equipment used to detect and study defects and
the methods and solutions for restoring the art object ...
Optimisation of Refractory Components of Sliding Gate Mechanism for Continuous Casting
(Universitatea "Dunărea de Jos" din Galați, 2009)
New design techniques have been developed to optimize refractory
components of sliding gate mechanism for continuous casting of steel. The overall
objective is to increase CC productivity as well as steel quality by using ...
On the Corrosion Behavior of Organic Nanocomposite Coatings
(Universitatea "Dunarea de Jos" din Galați, 2009)
Recently, researches on composite coatings of organic nature with the addition
of metallic oxide nanopowders have shown an increasing corrosion resistance of
metallic materials. Carbon steel shows an improved behavior ...
Studies About Electrochemical Plating with Zinc-Nickel Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)
The electrochemical deposition of zinc and combinations with elements of the
8th group of the Periodic System (nickel, cobalt, iron) have good properties for
anticorrosive protection, compare with pure zinc. For steel ...
Behaviour at Nitriding in Fluidized Layer of Austenitic Stainless Steels at the Temperature
(Universitatea "Dunărea de Jos" din Galați, 2007)
Nitriding at low temperatures, 450-500oC of austenic stainless steels lead to
the obtaining of the tough layers over 1000 HV005 but having thicknesses of tenths
of microns. Moreover, nitriding at 500ºC has determined the ...
The Study of Metal-old Wood Interactions Under the Influence of Pedological Factors
(Universitatea "Dunărea de Jos" din Galați, 2008)
In the manufacture of wood objects, for binding and strengthening were used
nails, cramps and other metallic elements, which in the archaeological site suffered
degradation and deterioration processes, specific to ...
Experimental Researches Concerning the Influence of the Oxynitrocarburizing Thermochemical Treatment Over the Structure and Corrosion Resistance of C40 Steel
(Universitatea "Dunărea de Jos" din Galați, 2009)
The aim of the paper is to present the results of the experimental researches
regarding the corrosion behaviour of C40 steel, thermochemical treated by oxidant
nitrocarburizing at 570°C. The thermochemical treatment was ...
