Wear Resistance of Sintered Composite Hardfacings under Different Abrasive Wear Conditions
Medžiagotyra, 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.

Cr2C3–NiCr VPS thermal spray coatings as candidate for chromium replacement [PDF]
, 2013 The present investigation has been carried out with the aim of determining the tribological behavior of a VPS chromium carbide coating both in the as-deposited and heat-treated conditions. A commercial powder of Cr2C3–25% NiCr was sprayed employing a VPS

Grinding and Abrasive Wear [PDF]
Proceedings 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.

Wear of human teeth: a tribological perspective [PDF]
, 2005 The four main types of wear in teeth are attrition (enamel-on-enamel contact), abrasion (wear due to abrasive particles in food or toothpaste), abfraction (cracking in enamel and subsequent material loss), and erosion (chemical decomposition of the tooth)

Analysis of Wear-Resistant Surface with Pangolin Scale Morphology by DEM Simulation
Applied Sciences, 2020 Based on the Discrete Element Method (DEM), an abrasive wear system composed of pangolin scale models and abrasive sand was established. The wear morphology of pangolin scale models under different velocities were simulated by PFC2D®.
