Two methods were used to create copper matrix composites enhanced with ZrB2 particles: hot pressing (HP) and laser
sintering. Prior to densification procedures, the Cu-Zr-B powder combination was mechanically alloyed. Scanning electron
microscopy (SEM) was used to examine changes in the microstructure of treated samples that were collected during the
cavitation test. Using vibratory equipment and the usual test procedure for cavitation erosion, the resistance to cavitation
erosion was examined. Regardless of the quantity of reinforcements, variations in the mechanical alloying time have a
significant impact on the cavitation erosion resistance of Cu–ZrB2 composites. Compared to hot-pressed samples, laser-
sintered samples exhibit superior resistance to cavitation erosion.
