Effects of plating on cavitation erosion.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1987 to study the cavitation erosion behavior of interface and base metal for platings, magneto-strictive erosion tests were carried out in a 3% NaCl solution using a 0.18% carbon steel specimen plated thinly with zinc, tin, chromium or nickel. When erosion attack extends to the interface between the plating and base metal, chromium or nickel plating which ...

Cavitation erosion in liquid nitrogen
Wear, 2018 Abstract Thermodynamic effects in cavitation become significant only when the critical-point temperature is close to the operating temperature of the fluid, as in the case of cryogenic fluids. Therefore, the understanding and the prediction of the cavitation effects in such cases is crucial in many applications - for example the turbopumps for liquid

Dynamics of the Cloud Cavitation and Cavitation Erosion.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1999 It is well known that a cloud cavitation is one of the most destructive forms of cavitation. The set of equations for the motion of a spherical bubble cloud is formulated. Behavior of bubble clouds are simulated numerically when the surrounding pressure is decreased from 50 kPa to a 10 kPa and then increased to 50 kPa.

Cavitation Light Emission and Cavitation Erosion
Journal of The Japan Institute of Marine Engineering, 2008 Cavitation bubbles emit a very weak light due to bubble collapse. It is expected that the light emission may be closely related to cavitation erosion. In order to confirm the relationship between the erosion damage rate and the light intensity, experiments were performed for a water orifice cavitation flow. A circular pipe was used and water-cavitation
