Cavitation Erosion-Corrosion Of Ship Propeller Materials

When a body of liquid is heated under a constant pressure or when its pressure is reduced at constant temperature by static or dynamic means due to friction in liquid, a state of pressure, called the vapour pressure, is reached where water starts to boil and gas/vapour bubbles start forming and growing. These bubbles, on colliding with a solid material, may explode and cause cavitation. This process is broadly termed as cavitation erosion [1]. And the adverse effect caused by oxidation of these eroded regions is called cavitation erosion‐corrosion.
