The role of dynamic recrystallization in dry sliding wear
Wear, 1980Abstract In dry sliding wear dynamic recrystallization gives a better understanding than grain boundary sliding and fatigue of the process near the contact zone. The process explains the low value of the deformation measured by grain thickness reduction and the absence of visible deformation marks in the case of low melting materials.

Temperature effects on adhesive wear in dry sliding contacts
Wear, 2010In many metal forming operations, frictional heating occurs at the interface due to a sliding contact. Generally, the controlling wear mechanism in the tribological system is attributed to adhesive wear. Understanding of the influence of temperature on wear mechanisms is needed for the development of materials and for optimization of the forming ...

Rolling-sliding dry wear testing — A vibration analysis
Wear, 1988Abstract Accelerations have been measured on a modified Amsler machine during the dry rolling-sliding wear testing of rail steels. With certain combinations of contact stress and creepage two types of periodic circumferential surface deformation of the test discs have been observed; these are termed “corrugations” and “facets”. Discs were examined by

Modeling of Dry Sliding Wear Using a Systematic Approach
Key Engineering Materials, 2006Virtual life testing is becoming a widely accepted methodology for predicting the life span of products. In this method, reliable models are important to predict different aspects of design performance, one of which is wear. Wear and has been a subject of numerous scientific and empirical investigations.

Effect of quartzite and granite in wear surfaces on dry sliding
Tribology - Materials, Surfaces & Interfaces, 2014AbstractThe wear surfaces abraded with quartzite and granite were subjected to scratch tests. Sharp and blunt indenters were used with various constant loads to produce controlled abrasive wear tracks. The characteristics of deformation mechanisms and material removal were further studied using a scanning electron microscope to determine the ...

Dry sliding wear behavior of AM50B magnesium alloy
Materials & Design (1980-2015), 2014Abstract Wear behaviour of AM50B magnesium alloy was tested using pin-on-disc configuration with carbon steel discs as counterpart on dry-sliding conditions. Wear rates and friction coefficients were measured in a sliding velocity range of 0.1–1 m s −1 and normal force range of 10–250 N. Worn surfaces were analysed using Scanning Electron Microscope

Dry sliding wear behavior of AM60B magnesium alloy
Wear, 2013Abstract Wear resistance of as-cast AM60B magnesium alloy was tested using pin-on-disc configuration with carbon steel discs as counterpart on dry-sliding wear conditions. Wear rates and friction coefficient were measured in a sliding velocity range of 0.1–1 m s−1 and using different normal force range 10–250 N.

Dry rolling-sliding wear of bainitic and pearlitic steels
Wear, 1992Abstract The rolling-sliding dry-wear behaviour of a series of bainitic steels and a pearlitic rail steel has been investigated over a wide range of contact stress and creepage conditions. A wear-testing machine designed and built at Leicester — LEROS — allows very high contact stresses to be combined with high creepages under well-controlled ...

Dry sliding wear behaviour of ZE41A magnesium alloy
Wear, 2011Abstract Wear resistance of the ZE41A magnesium alloy was tested using pin-on-disc technique and steel as counterbody on dry sliding conditions. Wear rates and friction coefficients were measured in a sliding velocity range of 0.1–1 m s −1 and in a normal forces range of 5–40 N.

Dry sliding wear of Cu–15Ni–8Sn alloy
Tribology International, 2010Abstract Using a pin-on-disc apparatus, the wear behavior of Cu–15Ni–8Sn alloy aged for different periods of time at 400 °C was investigated under dry condition. The results showed the wear rate was inversely proportional to the hardness of the alloy, but the maximum wear resistance was not consistent with maximum hardness.
