Abstract: The influence of the surface galvanic effects of 1Cr13 SS during cavitation damage hasbeen investigated in NaCl solutions. The results show that the solution 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.
