Determination of the cavitation resistance of glass-ceramic samples based on raw basalt and industrial waste raw materials for use in metallurgy

Abstract

The paper presents the results of the investigation of cavitation resistance of glass-ceramics based on basalt rocks from the Vrelo Kopaonik deposit and various waste industrial raw materials. The aim was to determine the possibility of using glass-ceramics as a substitute for metallic materials in the production of structural elements of mining and metallurgy equipment. The ultrasonic vibration method (with a stationary samples) was used for cavitation resistance testing, according to the ASTM G-32 standard. A change in the sample mass in function of the cavitation time was monitored for the evaluation of cavitation resistance. The level of degradation of the surface of the sample was quantified using the image analysis. The change in the morphology of the sample surface with the test time was followed by scanning electron microscopy.
