Improving Biocompatibility of Co-Cr Alloy Used in Dentistry by Surface Modification with Electrochemical methods-Corrosion of Untreated Co-Cr Alloy in Solution with Different pH
(Universitatea 'Dunărea de Jos" din Galați, 2014)The use of metals and alloys in dentistry has seen remarkable progress due to the deep research on their biocompatibility or the application of advanced technologies to improve surface properties by controlling ... -
Obtaining and Studying Tensile Strength for Non-Precious Alloys Based Cobalt
(Universitatea "Dunărea de Jos" din Galați, 2014)This paper presents aspects of obtaining non-precious dental alloys of Co-Cr-Mo alloys system and experimental tests to determine tensile strength, carried on standard flat specimens. -
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 ... -
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. ... -
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 ... -
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 ... -
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 ...
