.... The replacement pump was slightly oversized, which had the potential to cause erosion or cavitation. The impeller was coated with a brushable ceramic, which was typical for seawater impellers, for additional corrosion resistance and mechanical strength. The pump is a split case, double suction, with equal suction...

.... The martensitic stainless steels have yield stresses about twice those of carbon-manganese steels, typically about 550 MPa (80 ksi) compared with 250 MPa (36 ksi), and resistance to cavitation erosion that is superior to A-27. Some smaller hydroturbines and pumps have been fabricated from cast austenitic...

... with the classic spongy appearance of cavitation. Two changes were proposed: streamlining the part to avoid abrupt changes in fluid flow; and a change in alloy to a more corrosion-resistant material (304 or preferably 316) to increase the tenacity of protective films.

... Abstract Cavitation damage of diesel engine cylinder liners is due to vibration of the cylinder wall, initiated by slap of the piston under the combined forces of inertia and firing pressure as it passes top dead center. The occurrence on the anti-thrust side may possibly result from bouncing...

The heat exchanger tank and upper portion of the vaporizer tubes were not affected because the boiling action does not occur in those regions...
