AB  - In many industrial processes that include fluid flow, cavitation erosion of different engineeringstructures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,ceramic, and composite materials are usual candidates considered for application in such extremeconditions. In this study, the idea is to synthesize refractory ceramic material based on talc withthe addition of zeolite for utilization as protective coatings in cavitating conditions. Two talc-basedrefractories with zeolites from two Serbian deposits were produced. The behaviors of the samplesin simulated cavitation conditions were examined by an advanced non-destructive methodologyconsisting of monitoring mass loss and surface degradation using image analysis compiled withprincipal component analysis (PCA), interior degradation by ultrasonic measurements, and themicrostructure by a scanning electron microscope (SEM). Lower mass loss, surface degradation level,and modeled strength decrease indicated better cavitation resistance of the sample with Igros zeolite,whereby measured strength values validated the model. For the chosen critical strength, the criticalcavitation period as well as critical morphological descriptors, Area and Diameter (max and min),were determined. A Young’s elasticity modulus decrease indicated that surface damage influenceprogressed towards interior of the material. It can be concluded that the proposed methodologyapproach is efficient and reliable in predicting the materials’ service life in extreme conditions.

AB  - In the present study, an aluminum alloy A356 composite with addition of 5 wt% fly ash was synthesized and subjected to the cavitation erosion resistance test in order to find out if this material can be used in conditions where the cavitation erosion resistance is expected. Obtained results were compared with that of as-cast aluminum A356 alloy, confirming that composite possessed better cavitation erosion resistance than original alloy and that fly ash can be used as an effective reinforcement in metal matrix composites production. Scanning electron microscopy and optical microscopy was used for microstructural analysis. Phase identification of fly ash was carried out using X-ray diffraction analysis. Several methods for monitoring the cavitation erosion resistance of A356 alloy and corresponding composite were applied, such as: mass loss (Delta m), volume loss (Delta V), level of surface degradatiom (P/Po) and pit depth.

AB  - A cordierite/SiC composite was created in situ with reactive sintering at 1250 degrees C and 1300 degrees C. The cordierite precursor was made from commercially available spinel, alumina and quartz and was mixed with the comercial SiC powder to obtain composite materials during the sintering. It was found that cordierite particles bind efficiently with the SiC powder during sintering and that reactive sintering is an effective way to produce ceramics at a relativly low temperature. The goal of this investigation was to check the possibilities of using the silicon carbide-cordierite composite as a material resistant to the erosive wear. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Two kinds of SiC/cordierite samples were investigated, KS 50 and KS 30, with different mass contents of cordierite (w = 50 % and w = 30 % of cordierite). The mass loss and the level of surface degradation were measured before and during the experiment. The level of surface degradation of the samples was monitored using the Image-Pro Plus program for the image analysis. It was found that after 150 min the mass loss was below 1.3 mg and the surface degradation was below 7 %. The obtained results indicated that both samples exhibited an excellent erosion resistance during the cavitation experiment.

Cavitation damages of the alumina based specimens were tested by the modified vibratory cavitation set up. Erosion rates were measured based on the method developed for metallic samples, mass loss was measured during the experiment. Surface erosion was determined during the experiment simultaneously to mass loss measurements. Image Pro Plus Program was applied for surface analysis during testing. Results indicate that investigated material exhibit excellent mechanical properties and very good resistance to cavitation erosion.

AB  - Spark plasma sintering (SPS) of ZrC-SiC composite powders in the presence of LiYO2 sintering additive was studied. The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), which provided an intimate mixing of in-situ created ZrC and SiC powders. This composite powder and LiYO2 as additive were densified by spark plasma sintering. Microstructural features of the composite were investigated by XRD, SEM/EDS and AFM analysis. The sintered composite material possesses promising mechanical properties and excellent cavitation resistance which was observed with a cavitation erosion test. The values of Vickers microhardness and fracture toughness of the composite material are 20.7 GPa and 5.07 MPam(1/2), respectively.

AB  - Covalent bond in SiC ceramic request high temperature for its sintering. In order to put down sintering temperature of SiC ceramics we choose cordierite as phase between SiC particles. Reactive sintering is an effective way to produce ceramics at relatively low temperature. We have created in situ SiC/cordierite composite at 1250 degrees C. Cordierite precursor was made from commercially available spinel, alumina and quartz. The possibilities of using silicon carbide-cordierite material as resistant to the erosive wear was goal of this investigation. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Mass loss and level of degradation were measured before and during the experiment. Level of degradation of the samples was monitored using Image Pro Plus program for image analysis. Average erosion ring diameter as well as average erosion area were monitored during experiment. Obtained results pointed out that after 150 min sample exhibited excellent erosion resistance compared to metal and ceramic samples.

AB  - The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600oC). Carbothermal reduction process is greatly influenced by chemical composition of sepiolites and type of carbon used. Obtained SiC powders consist of fine β-SiC particles and did not retain the fibrous morphology of sepiolites.

AB  - The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine β-SiC powder at relatively low temperatures (1673-1873 K), was demonstrated. Obtained SiC powders consist of fine β-SiC particles and did not retain the fibrous morphology of starting sepiolites. Carbothermal reduction process, which was used in this study, is greatly influenced by catalyst addition (FeCl3, FeSi). In order to obtain pure SiC powders, it is necessary to completely remove all Mg-species, and catalytic influence of Fe is attributed to FeSi important role in reduction of Mg2SiO4 and MgO into Mg(g). Formation of SiC whiskers is observed only in samples with Fe introduced in form of iron-silicide (FeSi).

AB  - This paper presents monitoring of changes during thermal shock and cavitation testing for low cement concrete that was synthesized and sintered at 1600 degrees C for 3h. Water quench test was applied as an experimental method for thermal stability testing. Image analysis of the samples showed some level of deterioration at the surface and inside the samples before water quench test. During the testing, the level of samples destruction was increasing. Damages inside the samples and at the surface during the water quench test were correlated to the number of quench experiments. Models based on the damage level of both the surface and inside the bulk were proposed for calculation of the strength degradation. Cavitation damages of the samples were induced by the modified vibratory cavitation set-up. Mass loss and surface erosion were determined during the experiment. The results indicated excellent thermal shock behavior and resistance to cavitation erosion.

AB  - The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the modified glycine nitrate procedure (MGNP). Sintered products were characterized in terms of phase analysis, densities, thermal shock, monitoring the damaged surface area in the refractory specimen during thermal shock and ultrasonic determination of the Dynamic Young modulus of elasticity. It was found that a new phase between yttria and alumina is formed, which improved thermal shock properties of the spinel refractories. Also densification of samples is enhanced by yttria addition.

Analiza sinterovanih uzoraka podrazumevala je određivanje faznog sastava, praćenje oštećenja površine uzoraka usled termošoka, određivanje dinamičkog Jungovog (Young) modula elastičnosti ultrazvučnom metodom. Nađeno je da reakcijom spinela sa Y2O3 dolazi do formiranja nove faze koja poboljšava otpornost spinelne keramike prema termošoku.

AB  - 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 shock treatments was investigated. Thermal shock of the samples was measured using standard laboratory procedure, water quench test (JUS.B.D8.319.). Level of surface deterioration before and during quenching was monitored by image analysis. Ultrasonic measurements were used as nondestructive quantification of thermal shock damage in refractory specimens. When refractory samples are subjected to the rapid temperature changes crack nucleation and propagation occurs resulting in loss of strength and materials degradation. The formation of cracks decreases the density and elastic properties of material. Therefore measuring these properties can directly monitor the development of thermal shock damage level. Dynamic Young modulus of elasticity and strength degradation were calculated using measured values of ultrasonic velocities obtained by ultrasonic measurements. Level of degradation of the samples was monitored before and during testing using Image Pro Plus program for image analysis. The capability of ultrasonic velocity technique and image analysis for simple, and reliable nondestructive methods of characterization are presented in this investigation. It was found that both composite materials exhibit good thermal shock resistance.

AB  - In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Cordierite and silicon carbide are ceramic materials suitable for high temperature application with superior thermal shock resistance, low thermal expansion coefficient and good chemical resistance. The composite material could exhibit advantages of its constituents when the components have optimized properties and they are mixed in the proper ratio. Behavior of composite ceramics after thermal shock treatments was investigated. Thermal shock of quenching was monitored by image analysis. Ultrasonic measurements were used as non-destrusctive before and during quenching was monitored by image analysis. Ultrasonic measurements were used as non-destructive quantification of thermal shock damage in refractory specimens. Dynamic Young modulus of elasticity and strength degradation were calculated using measured values of ultrasonic velocities obtained by ultrasonic measurements.
