Which mechanism creates damage to a high-speed marine propeller due to exceeding its operational limits?

💡 Explanation

When a marine propeller exceeds speed limits inducing significant pressure drop, cavitation occurs because localized boiling creates vapor bubbles which then implode violently, causing micro-jet formation and erosion of the propeller surface. Therefore erosion is the direct result, rather than deformation, corrosion or fatigue, which rely on different stresses or material interactions.
