A cavitation facility was used to study the erosion corrosion behavior of UNS N010665 cast alloy in seawater. The cavitation tests were made at a frequency of 20 KHz and at temperatures of 250C. Cavitation conditions caused an active shift in the free corrosion potential for UNS N010665 alloy. The work included measurements of free corrosion potentials and mass loss in the presence and absence of erosion. Cavitation also increased the rate of mass loss of this alloy by several orders of magnitude with respect to stagnant conditions. Another set of cavitation experiments was also carried out for this alloy in ditilled medium in order to distinguish between the mechanical and electrochemical factors that contribute to metal loss. Results indicated that the mechanical factor has an over riding role in metal loss of this alloy. Cavitation made the surface of this alloy very rough exhibiting large cavity pits in the middle region of the attacked area as revealed by the scanning electron microscope (SEM). Mechanical factors were determined to be the leading cause of metal loss.

Keywords: Nickel based alloy, distilled water, metal loss, mechanical and electrochemical factors.
