Thermal stability of cordierite/silicon carbide composites after cyclic thermal shock
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
In this paper composite material made from silicium carbide and cordierite was used in experiments. Behavior of the material in conditions of rapid temperature changes was investigated. Modified water quench test was applied ...
Electrophoretic deposition of thin alumina films from water suspension
(Elsevier, Amsterdam, 2002)
Alumina water suspensions have been prepared for thin alumina film deposition on steel. The type and quantity of deflocculant have been determined using zeta potential and viscosimetric measurements. The deposition was ...
The use of image analysis program for the determination of surface deterioration of refractory specimen during thermal shock / Korišćenje programa za analizu slike za određivanje stepena oštećenja vatrostalnog uzorka pri termošoku
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2006)
During examination of refractory specimen, one of the most important characteristics is their resistance to thermal shock. Standard method of testing is based on monitoring the surface shanging during thermal stability ...
Influence of formation conditions and precursor viscosity on mean fiber diameter formed using the relating disk method
(Elsevier, Amsterdam, 2000)
Alumina ceramic fibers were produced from aluminum-hydroxidechloride based sol. Polyvinyl alcohol and surface active material were applied to adjust the rheological characteristics of the: sol. The rotating disk formation ...
Image analysis of protective layer of zinc on steel obtained using the hot process / Analiza slike za karakterisanje zaštitnog sloja cinka na čeliku dobijenog toplim cinkovanjem
(Savez inženjera metalurgije Srbije, Beograd, 2003)
The procedure for measuring the thickness of anticorrosion protective layer of zinc on steel is given. The metallographic images are used for this measurement. Results are statistically handled and results are used to ...
Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods
(Elsevier Sci Ltd, Oxford, 2008)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Behavior of composite ceramics after thermal ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
The influence of the deposition parameters on the porosity of thin alumina films on steel / Uticaj parametara elektroforetskog taloženja praha aluminijum-oksida iz vodenih suspenzija na poroznost dobijenih tankih filmova na čeliku
(Serbian Chemical Society, Belgrade, 2004)
The influence of the deposition parameters on the porosity of thin alumina films electrophoretically deposited on steel from aqueous suspensions was investigated. The effects of the applied voltage, deposition time, ...
The use of image analysis for the interaction of 1,3,5-trisubstituted isocyanurates with oxidizer and different binders in composite materials / Korišćenje analize slike za utvrđivanje interakcije 1,3,5-trisupstituisanih izocijanurata sa oksidansom i različitim vezivima u kompozitnim gorivima
(Association of Chemical Engineers of Serbia, 2006)
Composite propellants are non-homogenous propellants and comprise primarily crystalline oxidizer and metal fuels uniformly suspended in a resin binder. The strength of the bonds between the polymer matrix and the oxidizer ...
Assessment of viscoelastic crack bridging toughening in refractory materials
(Elsevier Sci Ltd, Oxford, 2008)
Viscoelastic bridges can be formed in refractory ceramics while cooling from high temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress intensity factors leading to higher resistance ...
