AB  - In the paper, samples of protective coatings based on pyrophyllite were examined. The initial sample of
pyrophyllite was obtained from the Parsovići deposit, Konjic, Sarajevo, AD Harbi BiH. Pyrophyllite
samples were subjected to micronizing grinding to a filler grain size of 20 μm. XRD, SEM and optical
microscopy methods were used to characterize the obtained fillers based on pyrophyllite. The optimal
composition of protective coatings based on pyrophyllite and the manufacturing process were determined.
The resistance of refractory coatings to the effect of cavitation was experimentally determined using the
ultrasonic vibration method with a stationary sample according to the ASTM G32 standard. Based on the
value of the cavitation rate, the analysis of the formation and development of damage to the surface of the
samples, the possibility of applying a protective coating in the conditions of exploitation in which the
occurrence of corrosion and cavitation is expected was assessed.

AB  - U radu je ispitivana otpornost pod dejstvom kavitacije uzoraka sinterovanog pirofilita. Polazni
uzorak pirofilita iz ležišta Parsović- BiH mleven je u vibracionom mlinu na granulaciju 20μm,
presovan je i sinterovan na temperaturama (ºC): 1000; 1100; 1200. Za procenu kavitacione
otpornosti praćena je promena mase uzorka u funkciji vremena delovanja kavitacije. Primenjena je
ultrazvučna vibraciona metoda sa stacionarnim uzorkom prema standardu ASTM G32. Izračunate
su kavitacione brzine za sve uzorke, kao osnovni pokazatelj otpornosti materijala pod dejstvom
kavitacije. Promena morfologije površine uzorka sa vremenom ispitivanja praćena je primenom
skenirajuće elektronske mikroskopije. Na osnovu vrednosti kavitacione brzine i analize morfologije
oštećenja površine određena je kavitaciona otpornost ispitivanih uzoraka na bazi pirofilita. Dobijeni
rezultati ukazuju da uzorci sinterovanog pirofilita imaju zadovoljavajuću otpornost na dejstvo
kavitacije i mogu se primeniti u uslovima manjih kavitacionih opterećenja.
AB  - The resistance under the action of cavitation of sintered pyrophillite samples was investigated. The initial sample of pyrophillite from the Parsovic-BiH deposit was ground a vibrating mill to a granulation of 20 mμ, pressed and sintered at temperatures (⁰C): 100; 1100; 1200. To assess cavitation resistance, the change in sample mass as a function of cavitation time was monitored. The cavitation erosion test was performed using the ultrasonic vibratory cavitation test method according to the ASTM G-32 standard. Cavitation velocites were calculated for all samples, as a basic indicator of the resistance of the material under the action of cavitation. The change in the morphology of the surface with the test time was followed by scanning electron microscopy. Based on the values of cavitation velocity and analysis of the surface damage morphology, the cavitation resistance of the tested samples based on pyrophillite was determined. The obtained results indicate that the samples of sintered pyrophillite have satisfactory resistance to the action of cavitation and be applied in conditions of lower cavitation loads.

AB  - The paper examines the resistance to the effect of cavitation of glass-ceramics based on basalt. Two types of samples were investigated: cast and sintered samples based on basalt.The cavitation erosion test was performed using the ultrasonic vibratory method with a stationary sample. To measure the cavitation resistance, a change in sample mass in function of the cavitation time was monitored. The change in the morphology of the surface with the test time was followed by scanning electron microscopy. The level of the surface degradation of the samples was quantified using the image analysis. Samples were tested under the same conditions. A comparison of the properties of the resistance to the effect of cavitation was performed in relation to the calculated cavitation rates. The results showed the high degree of cavitation resistance of the tested samples and the possibility of their application in conditions of high cavitation loads.

AB  - For the development of the Lost Foam refractory coatings with controlled rheologic properties, the influence of the mechanical activation process on the cordierite-based filler's properties change was examined. First of all, the test referred to the change offiller particles' size and shape, as well as to dispersion ability and stability of the coating suspension. Cordierite was obtained by synthesis in a solid state, out of the mass consisting of kaoline, alumina, quartz, sepiolite. For characterization purposes, the following methods were used: X-ray diffraction, differential thermal analysis, SEM and optical microscopy. Mechanical activation of filler was performed in a vibrating mill. The upper boundary of the grain size was 100% -30 x 10-6 m, the times were (min): 15; 30; 60. The new composition of Lost foam refractory coatings has been developed with a change of the coating production process, as well. These newly synthesized coatings proved to be effective in terms of a positive influence on a surface quality, structural and mechanical properties of aluminium castings. Test results may be useful to have the Lost Foam refractory coatings specified together with other process parameters used for the production of castings according to this casting method.
