Studies and Research on Treatment of Titanium Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)
Titanium and its alloys have an extended use due to special properties. The
paper highlights the TiZr alloy intended to manufacture prostheses, the influence of
plastic deformation on the properties and structure. Applied ...
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 ...
Influence of Alloying Elements on Corrosion Resistance of Some Iron - based Sintered P/M Alloys
(Universitatea "Dunărea de Jos" din Galați, 2015)
In this paper is described the influence of alloying elements on corrosion
behavior of sintered iron parts. The compacts were sintered at 1,150 °C and the
sintering time was 60 minutes. After microstructural studies, the ...
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 ...
