Fracture Characteristics of Abrasive Particles

Key Engineering Materials, 1997
Particle degradation occurs during abrasive processes like three-body abrasion and erosion. With a single particle crusher strength tests have been performed with AI2O3 powders in order to gain more information about the fracture characteristics of the abrasive particles. The mean fracture force increases with increasing particle size and is larger for

Ball-cratering abrasion tests with large abrasive particles

Tribology International, 2006
Abstract The application of a ball-cratering method to test three-body abrasive wear of bulk materials in the presence of large abrasive particles has been investigated. Four types of abrasive particles of different sharpness were used to make slurries: glass beads, silica sand, crushed quartz and alumina.

Movement patterns of abrasive particles in three-body abrasion

Wear, 1993
The movement patterns of abrasive particles in three-body abrasion are very important to the wear of materials. In the present paper, the movement of a single abrasive particle could be observed in detail through new wear apparatus for three-body abrasion.

Nanochemistry of Ceria Abrasive Particles

MRS Proceedings, 2004
AbstractSurfaces of ceria (CeO2) particles have been studied by electron energy-loss spectroscopy in a field-emission gun scanning transmission electron microscope. All the ceria particles analyzed contained Ce3+ at the surface. Rare-earth impurities such as La were enriched at the surface and were observed for particles ranging from tens to hundreds ...

Particle Velocity in Abrasive Waterjets

2020
Abrasive particle velocity plays a key role in material removal in abrasive waterjet (AWJ) machining. Understanding how certain operating conditions effect the speed of abrasive particles is important for the improvement of the AWJ process. Without a method of measuring abrasive speed, it is difficult to evaluate the cutting performance of an AWJ using

Adhesive transfer to abrasive particles in abrasion testing

Wear, 2011
Abstract The definition of “abrasive wear” endorsed by the ASTM G2 Committee on Wear And Erosion is: “wear due to hard particles or hard protuberances forced against and moving along a solid surface” [1] . There are many models applied to abrasion that are based upon idealized cones (and other shapes) as an abrasive particle imposed on and moving in

Sharpness of abrasive particles and surfaces

Wear, 2004
Abstract The concept of asperity sharpness has recently been developed into a technique for the description of abrasive particle shape. This paper reveals further discoveries on the nature of particle shape and applies sharpness concepts to nominally planar abrasive surfaces composed of self-arranged particle stacks.
