An SEM-Based Method for the Evaluation of the Cavitation Erosion Behavior of Materials

Damages on steel surface at the incubation stage of the vibration cavitation erosion in water

“…Recently, SEM (Scanning Electro Microscope)-based technology is widely used to study the formation of the erosion pit and its evolution at different cavitation erosion stages [8]. From pitting tests, the flow aggressiveness and impact loads can also be determined [9].…”

Effects of cylinder head temperature and coolant velocity on the erosion behavior of water jacket in a diesel engine

“…Thus, the increased coolant velocity only has a mechanical impact on the surface through the increased shear force. Compared with the zero velocity condition, the surface material was easily eroded due to the physical process caused by the flow shear stress under higher coolant velocity conditions [34][35][36][37][38].…”

“…When the specimen temperature was higher, the formation and collapse of the bubbles were repeated more vigorously [34]. This indicates that the pit could be created by the micro jet impact from repeated formation and collapse of bubbles at elevated surface temperatures [37,[40][41][42][43]. The results shown in Fig.…”

The Effect of Alloy Microstructure on Their Cavitation Erosion Behavior in Seawater

“…Cavitation erosion phenomenon is very complicated, and materials having different properties will react in different ways [1][2][3][4]. The main mechanism of a material's reaction to attack centers around mechanical stressing seems clear from available information.…”
