An in vitro study of the wear mechanism of a leucite glass dental ceramic

open access: yesBiosurface and Biotribology, 2015
Ceramics and glass-ceramics are materials of choice for dental crowns due to their attractive hardness, biocompatibility, etc. However, a major problem with their usage is the observed high wear of either the opposing dental enamel or both the enamel and

Sliding wear behaviour of salt bath nitrided 316LN austenitic stainless steel

open access: yesApplied Surface Science Advances, 2023
The wear behaviour of AISI 316LN austenitic stainless steel has been studied by varying the duration of nitriding. AISI 316LN steel was nitrided using salt bath nitriding which consist of a mixture of 70:30 ratio of alkaline cynates and carbonates ...

The influence of laser hardening on wear in the valve and valve seat contact [PDF]

open access: yes, 2009
In internal combustion engines it is important to manage the wear in the valve and valve seat contact in order to minimise emissions and maximise economy.

Wear-mechanism modelling [PDF]

open access: yes, 1993
Goals of the program are to calculate the surface temperatures in dry sliding, develop a soft wear tester for ceramics, survey the wear mechanisms in brittle solids, and couple the temperature calculations with models to give wear maps for brittle solids. (DLC)

Dynamic Response Analysis of Planar Multilink Mechanism considering Wear in Clearances

open access: yesShock and Vibration, 2019
Clearance wear is one of the factors that affects dynamics for mechanical systems. A numerical methodology suitable for modeling and calculation of wear at multiple revolute clearance pairs in the field of the planar multilink mechanism is proposed.

Bionic design perspectives based on the formation mechanism of dental anti-wear function

open access: yesBiosurface and Biotribology, 2017
Human teeth are the important masticatory organ and therefore are subjected to friction and wear everyday. Both the loading condition and the environment are relatively complex in the mouth, however, normally human teeth can serve in mouth all their time

Experimental Study on Wear Characteristics of PCBN Tool with Variable Chamfered Edge

open access: yesChinese Journal of Mechanical Engineering, 2019
Owing to heavy dynamic and thermal loads, PCBN tools are seriously worn during hard cutting, which largely constrains the improvement of their machining performance.

Design and development of a novel sliding friction and wear tester with complex working conditions

open access: yesScientific Reports, 2021
Serious wear phenomena occur in mining machinery under complex working conditions, and the wear of machine parts is primarily caused by the synergistic effect of adhesive wear, abrasive wear, corrosive wear, etc.

Lava channel formation during the 2001 eruption on Mount Etna: evidence for mechanical erosion [PDF]

open access: yes, 2005
We report the direct observation of a peculiar lava channel that was formed near the base of a parasitic cone during the 2001 eruption on Mount Etna. Erosive processes by flowing lava are commonly attributed to thermal erosion.
