The cavitation erosion is the phenomena that causes degradation of fluid flow machinery components due to repetitive implosion of cavitation bubbles adjacent to the solid surface. Cavitation erosion is a complex phenomenon, which includes not only hydrodynamic factors of liquid, but also properties of erodible material e.g. microstructure, hardness or Young modulus. In order to reduce the negative impact of erosion on machine components, there are many methods to increase cavitation erosion resistance. The paper discusses the correlations between structural and mechanical properties and the resistance to cavitation erosion (CER) of pure materials, their alloys and coatings. Methods to increase CER have also been described - using heat / thermo-chemical treatment and application of coatings by various methods.

Hydraulic components are coated by thermal spraying to protect them against cavitation erosion. These coatings are built up by successive deposition of single splats. The behavior of a single splat under mechanical loading is still very vaguely understood. Yttria-stabilized zirconia (YSZ) and stainless-steel splats were obtained by plasma spraying onto stainless steel substrates. The velocity and temperature of particles upon impact were measured and the samples were subsequently exposed to cavitation erosion tests. An acoustic cavitation simulation estimated the water jet velocity and hammer stresses exerted by bubble collapse on the surface of the specimen. Although the results suggested that high stress levels resulted from cavitation loading, it was clear that weak adhesion interfaces played a crucial role in the accelerated cavitation-induced degradation.

“…On the one hand, material properties such as hardness and yield strength contribute significantly to cavitation erosion. [6] One the other hand, variation in operation parameters such as the distance between the ultrasonic horn tip and target surface can also lead to considerably different cavitation erosion results. [7,8] The joint action of ultrasonic effect and liquid properties might alter the cavitation erosion resistance of materials.…”

To evaluate the influence of liquid property on cavitation erosion resistance of the copper alloy, an experimental investigation is performed with the ultrasonic vibratory apparatus. Liquid media of deionized water, tap water, and 3.5 wt.% NaCl solution are selected. The cumulative mass loss rate and microhardness are measured and surface morphology observed at different erosion time. The results show that the cumulative mass loss increases consistently with the erosion time, and the highest cumulative mass loss rate is witnessed in tap water. The erosion time at which the maximum cumulative mass loss rate is reached is the shortest with the 3.5 wt.% NaCl solution. Surface morphology testifies the rapid evolution of small cavitation erosion pits into large eroded area in the specimen surface submerged in the deionized water and tap water. In comparison, the specimen surface in the 3.5 wt.% NaCl solution is featured by insignificant cavitation erosion, and plastic deformation remains predominant for a long erosion time. The initiation and development of micro‐cracks are remarkable in tap water. In the 3.5 wt.% NaCl solution, the progression of cavitation erosion is mitigated relative to the other two cases, and cavitation erosion pits remain the predominant constituents of the erosion pattern as the erosion time increases. The hardening layer is found beneath the specimen surface, and the 3.5 wt.% NaCl solution is responsible for the thickest hardening layer. As cavitation erosion develops, the softening phenomenon is salient with consistent flaking off of surface layers.
