cavitation erosion

cavitation erosion

[‚kav·ə′tā·shən i′rō·zhən]
(metallurgy)
Attack of metal surfaces caused by the collapse of cavitation bubbles on the surface of the liquid and characterized by pitting. Also known as cavitation corrosion; cavitation damage.

For analysis behavior of the flow, we will use the following parameters: speed [m/s], direction (line of flow), pressure [MPa], turbulent kinetic energy, [[m.sup.2]/[s.sup.2]] volume fraction of pair phase [%], cavitation erosion speed [nm/hour].
The part had an initial cycle of 5 minutes then inspected for any cavitation erosion and damage.
Cavitation in hydraulic machinery leads to the problems such as cavitation erosion, vibration, pressure pulsation, and noise [1].
Besides, due to the continuously impingement effect of the burst cavitation bubbles, cavitation erosion would develop on the blade surfaces.
The bursting bubbles in this manner would lead to the long run to corrosion of the valve surface over the long run further amplifying cavitation and cavitation erosion.
Cavitation erosion in aircraft engine and control systems is a major concern in hydrodynamic power units.
Mechanisms of cavitation erosion and characteristics of cavitation pits produced have been studied extensively [5-8].
The first observation of cavitation erosion has been reported by Thorneycroft and Barnaby [59] much earlier than any data on sonochemistry or sonoluminescence.
With the recent increase of industrial applications for composites and various coatings, cavitation erosion resistance of these materials is of interest to designers and engineers.
The 20 papers here, about half of the presentations, discuss such topics as the formation and occurrence of non-metallic inclusions of silicon-doped steel during continuous casting, effects of carbon migration on sulfide stress corrosion cracking behavior of dissimilar joints in a wet hydrogen sulfide environment, the gas tungsten arc cladding of titanium-nickel overlays onto the carbon steel and stainless steel for cavitation erosion resistance, the electromagnetic characteristics of iron-based microwave absorbing materials, and surface-texturing single-crystalline silicon wafers.
