A study of the wear process related to twin-screw extruders [PDF]

open access: yes, 1996
Extruders are used in a wide range of process industries and high reliability is essential if cost effective manufacturing is to be maintained. A critical part of twin-screw extruders is the barrel that must withstand many different wear and corrosion ...

Micro-abrasion resistance of thermochemically treated steels in aqueous solutions: Mechanisms, maps, materials selection [PDF]

open access: yes, 2008
The area of micro-abrasion is an interesting and relatively recent area in tribo-testing methodologies, where small particles of less than 10 μm are employed between interacting surfaces.

Some remarks on particle size effects on the abrasion of a range of Fe based alloys [PDF]

open access: yes, 2010
The low-stress three body abrasion behaviour of a range of steels was investigated. The tests were carried out in a rubber wheel tester (according to ASTM G65-94, reapproved in 2000) at room temperature.

Comparison of Different-Energy-Level Abrasion in Los Angeles and Micro-Deval Apparatuses Using Mass Loss and Rounding of Sediment Particles

open access: yesApplied Sciences, 2023
During the routing of coarse particles in sedimentary environments, the particles are subjected to abrasion, leading to mass loss and changes in the particles’ morphology. The particles become more spherical, rounded, and smooth.

Variation of abrasive feed rate with abrasive injection waterjet system process parameters

open access: yesJournal of Korean Tunnelling and Underground Space Association, 2015
A new rock excavation method using an abrasive injection waterjet system has been developed to enhance the efficiency and reduce the vibration of tunnel excavation. The abrasive feed rate is an important factor for the cutting performance and the economical efficiency of waterjet-based excavation.
