Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow is present, which contains equipment such as turbine blades, high-speed propellers, or
pump parts. Cavitation erosion usually causes surface degradation of material with defects that appear in
the form of pits and fractures. Such loss of material leads not only to surface degradation but usually also
to strength deterioration with the potential risk of failure and therefore also to shortening of material
lifetime, thus requiring additional costs for failure analysis, repair, and replacement of parts. This paper
will present the results regarding the resistance of various engineering materials to cavitation erosion. As
materials, austenitic stainless steel 316L and CuAlNi shape memory alloy are selected and studied. The
comparison of the behavior between these two... materials in cavitation erosion conditions will be shown
based on the results of mass loss and morphology analysis of the pits formed at the surface over time. Image
analysis tools will be applied in order to quantify the surface damage level and to analyze selected
morphology descriptors.
