concentrationand area ratio of bubble unacted surface to the bubble-acted surface greatly influencethe cavitation damage of the alloy. The surface galvanic effects can speed up thedissolution rate of the alloy, and the mass loss per area of the alloy increases linearlywith the area ratio of bubble unacted surface to the bubble acted surface of the alloy. Key words:galvanic effect; cavitation......
