The paper presents the results of synthesis and characterization of new refractory coatings based on basalt and epoxy system. Coatings are intended to protect the surfaces of parts of equipment and various structures in civil and mechanical engineering and metallurgy which are exposed to wear, corrosion, or cavitation during exploitation. Coating composition, procedures for preparation of components from coating composition, synthesis procedures, and application of coatings are investigated. Several methods are used to characterize the coating: X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), optical microscopy and ultrasonic vibration method with a stationary sample according to ASTM G32 standard. Material resistance to the action of cavitation is determined using the ultrasonic method. In order to monitor the formation and development of surface damage on samples under the effect of cavitation, the morphology of surface coating damage is analysed using scanning e...lectron microscopy. Results show high resistance of the tested basalt-based coatings under the action of cavitation, with low cavitation rate (0.04 mg/min), low mass losses of coating and minor surface damage during exposure. This indicates the possibility of applying this type of refractory coating for the protection of various metallic and non-metallic structures in conditions of wear and cavitation.
