Monitoring cavitation erosion in materials is crucial for their performance in environments
characterized by severe fluid flow conditions. Materials such as metals, ceramics, and composites,
commonly used in these applications, must possess specific mechanical properties to effectively
resist cavitation erosion. Additionally, various environmental factors, including different chemical
solutions, can significantly alter a material's response to cavitation. In this study, the impact of the
marine environment was investigated using a prepared NaCl solution, following the standard
procedure of ISO 11130:2017(E), to evaluate its influence on further cavitation erosion exposure of
materials. Cavitation erosion tests were performed on steel samples (42CrMo4) after immersing
them in NaCl solution for 120 days. An ultrasonic vibratory test, conducted according to the ASTM-
32-16 standard, was employed to assess the material's erosion resistance. To evaluate the extent of
cavitation damage, various methods were utilized, including monitoring mass loss and calculating
the mass loss rate, as well as conducting image analysis to quantify pit dimensions, the number of
pits, and overall degradation levels. The results provide valuable insights into the relationship
between material properties, environmental exposure, and cavitation erosion, with implications
for the design and selection of materials for use in marine and intensive fluid flow applications.
