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.

Cavitation erosion when experienced, normally leads to significant additional repair and maintenance costs or component replacement.
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.
The cavitation erosion behavior of metallic materials is investigated in laboratory conditions through tests performed on various facilities: vibratory apparatus, high-pressure water jet systems, cavitation tunnels, rotating disk devices.
Mechanisms of cavitation erosion and characteristics of cavitation pits produced have been studied extensively [5-8].

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.
FLOW-3D Cast can tackle virtually all casting processes and contains models specifically designed for detecting design problems, including tracking of surface oxides, air entrainment, shrinkage porosity, micro-porosity, and cavitation erosion.
There is also negligible wear on the knives and the die plate because the design of the system prevents cavitation erosion of the die plate.
The investigation of the dynamics of spherical cavitation bubbles is of no direct interest for the explanation of cavitation erosion, because bubbles close enough to a boundary to cause damage will always collapse aspherically.
A standards-issuing organization, ASTM International, wants to hear from engineers who have an interest in cavitation erosion testing.
