Mechanisms of Dust Erosion

SAE Technical Paper Series, 1964
<div class="htmlview paragraph">This paper shows the results of an experimental investigation of the nature and characteristics of erosion of metals by high-speed impingement of airborne dust particles. The influence of various parameters upon the rate of erosion is shown.

Erosion spalling mechanism

Wear, 1992
Abstract Multiparticle erosion is accompanied by three types of damage spalling resulting from solid compression on impulse loading. Focusing of rarefaction waves on particle sides causes longitudinal channel cracks to form under the contact zone. Further damage of the surface layer takes place as multiple longitudinal spalling.

Erosion mechanism and erosion products in carbon-based materials

Journal of Nuclear Materials, 2002
Abstract Plasma/material interaction was studied in disruption simulation experiments at the plasma gun facility MK-200. Graphite and carbon-fibre composites were exposed to pulsed energetic plasma under heat loads typically expected for disruptions in future tokamaks.

Slurry erosion characteristics and erosion mechanisms of stainless steel

Tribology International, 2014
Abstract In the present study, slurry erosion experiments of stainless steel SUS-304 were carried out using new advanced erosion test rig, where the multiphase flows of alumina sand and water were utilized as the erodents. The results show that erosion rate was initially high and gradually reduced over the testing time.

Cavitation Erosion Mechanism Based on Analysis of Erosion Particles

Journal of Tribology, 2008
The mechanism of cavitation erosion is investigated in detail through observations of the removed particles from pure aluminum (Al-99.999). The particles removed during the incubation stage have distinctive characteristics compared to those removed in the subsequent stages.

Modelling mechanical consequences of erosion

Géotechnique, 2010
The process of internal erosion of fine particles from a soil progressively narrows the grading of the soil. Development of a continuum model for the mechanical consequences of erosion has taken inspiration from two-dimensional discrete element analyses of assemblies of circular discs of various gradings.

Micro-Mechanics of Contact Erosion

Applied Mechanics and Materials, 2014
In the present paper a simulation framework is presented coupling the mechanics of fluids and solids to study the contact erosion phenomenon. The fluid is represented by the Lattice Boltzmann Method (LBM) and the soil particles are modeled using the Discrete Element Method (DEM).

Mechanisms of polymer degradation and erosion

Biomaterials, 1996
The most important features of the degradation and erosion of degradable polymers in vitro are discussed. Parameters of chemical degradation, which is the scission of the polymer backbone, are described such as the type of polymer bond, pH and copolymer composition.

Mechanical erosion by flowing lava

Contemporary Physics, 2008
Hot lava is a viscous fluid that, driven by gravity, moves along the Earth's surface. Intuitively, one attributes constructional properties to lava–it accumulates in volcanic landforms, compound lava fields and, in the end, entire mountains. On the other hand, there are also examples of the erosive power of lava: on Earth and especially on other ...

Erosion Debris Particle Observations and the Micromachining Mechanism of Erosion

A S L E Transactions, 1985
Erosion debris particles produced by particle impact erosion of pure Ni and a stainless steel have been examined in the scanning electron microscope for the purpose of determining whether micro-machining is an operative mechanism of erosion by alumina particles. Macroscopic machining chips generally exhibit well-defined lamellae on the side of the chip
