cavitationresistant
Cavitationresistant denotes materials, coatings, or components engineered to withstand cavitation, the rapid formation and collapse of vapor bubbles in a liquid near a solid surface. Cavitation occurs when local pressures drop below the liquid’s vapor pressure, commonly in pumps, propellers, valves, and turbines. The collapse of bubbles near a surface generates high-energy jets and shock waves that can erode material, cause pitting, crack growth, and fatigue, reducing efficiency and service life.
Factors influencing cavitation resistance include the material’s hardness and toughness, fatigue strength, and ability to absorb
Design approaches also help: optimizing geometry to minimize low-pressure regions, smoothing surfaces, and adding sacrificial liners
Assessment typically involves laboratory cavitation erosion tests, measuring mass loss, erosion rate, and incubation period; standards
