abstract = "In many industrial processes that include fluid flow, cavitation erosion of different engineering
structures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,
ceramic, and composite materials are usual candidates considered for application in such extreme
conditions. In this study, the idea is to synthesize refractory ceramic material based on talc with
the addition of zeolite for utilization as protective coatings in cavitating conditions. Two talc-based
refractories with zeolites from two Serbian deposits were produced. The behaviors of the samples
in simulated cavitation conditions were examined by an advanced non-destructive methodology
consisting of monitoring mass loss and surface degradation using image analysis compiled with
principal component analysis (PCA), interior degradation by ultrasonic measurements, and the
microstructure 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 critical
cavitation 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 influence
progressed towards interior of the material. It can be concluded that the proposed methodology
approach is efficient and reliable in predicting the materials’ service life in extreme conditions.",
