Cavitation resistance of refractory samples based on talc and domestic zeolite from the Zlatokop deposit

Abstract

The paper presents the results of the research cavitation erosion behavior of samples based on talc with addition of domestic zeolite from the Zlatokop deposit. Samples based on talc with 15 % of zeolite, from Zlatokop (Vranjska Banja), sintered at 1200ºC were used in this investigation. Resistance to cavitation was monitored by the ultrasonic vibratory cavitation set up with a stationary specimen and measuring respectively determining the specimens' mass loss. Image analysis and Young's modulus of elasticity were used to determine the level of degradation of the sample surface and sample's volume. Obtained results showed good resistance of the refractory samples based on talc and zeolite to the cavitation erosion, which indicates the possibility of application ceramic samples based on talc and zeolite in various areas of industry where the presence of destruction due to the effect of cavitation is expected.
