Wear Resistance of Sintered Composite Hardfacings under Different Abrasive Wear Conditions

open access: yesMedžiagotyra, 2017
The article focuses on vacuum liquid phase sintered (PM) composite hardfacings and their behaviour under different abrasive wear conditions. Hardfacings studied contained 30 – 50 vol % fine, coarse or multimodal (fine and coarse) hardmetal reinforcement.

Grinding and Abrasive Wear [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, 1970
To explore the relationship between grinding and abrasive wear, a range of differing experiments has been performed. These include simple wear tests, dynamometer measurements of grinding forces, simple scratch tests with both idealized indentors and abrasive grits, and the microscopic examination of abrasive wheels and worn surfaces of steel.

Aliasing Signal Separation of Superimposed Abrasive Debris Based on Degenerate Unmixing Estimation Technique

open access: yesSensors, 2018
Leakage is the most important failure mode in aircraft hydraulic systems caused by wear and tear between friction pairs of components. The accurate detection of abrasive debris can reveal the wear condition and predict a system’s lifespan.
