Structure and wear mechanisms of nano-structured TiAlCN/VCN multilayer coatings [PDF]

open access: yes, 2007
Dry sliding wear of transition metal nitride coatings usually results in a dense and strongly adhered tribofilm on the worn surface. This paper presents detailed electron microscopy and Raman spectroscopy characterizations of the microstructure, a newly ...

Lubrication Performance of α-Zirconium Phosphates as an Anti-Wear Additive in Vegetable Oil-Based Anhydrous Calcium Grease

open access: yesLubricants, 2018
Vegetable oil has significant potential as a base oil, and substitute for mineral oil in grease formulation due to its biodegradability, low toxicity and excellent lubrication. This paper studied the development of vegetable oil-based greases with α

Preliminary Study of the Effect of Micro-Scale Dimple Size on Friction and Wear under Oil-Lubricated Sliding Contact

open access: yesTribology Online, 2011
One of the conclusively presumed effects of micro-scale dimples under oil-lubricated conditions is that can serve as oil reservoirs and play a role in promoting the retention of a lubricating film.

Tribological Properties of Structural Ceramics [PDF]

open access: yes, 1989
The tribological and lubricated behavior of both oxide and nonoxide ceramics are reviewed in this chapter. Ceramics are examined in contact with themselves, other harder materials and metals. Elastic, plastic and fracture behavior of ceramics in solid state contact is discussed. The contact load necessary to initiate fracture in ceramics is shown to be

Effect of Si element on the interfacial reaction of Ti3SiC2 reinforced Al matrix aomposites

open access: yesMaterials Research Express, 2021
The interfacial reaction behavior of Ti _3 SiC _2 /Al andTi _3 SiC _2 /Al-10si matrix composites at high temperature was studied by XRD and SEM. The results showed that the reaction between Ti _3 SiC _2 and Al matrix is ${{\rm{Ti}}}_{3}{{\rm{SiC}}}_{2}+{\

A fundamental mechanism for carbon-film lubricity identified by means of ab initio molecular dynamics

open access: yes, 2016
Different hypotheses have been proposed to explain the mechanism for the extremely low friction coefficient of carbon coatings and its undesired dependence on air humidity.

The effect of laser in-situ induced graphene-like micro-texture on the friction and wear properties of ductile cast iron

open access: yesJournal of Materials Research and Technology, 2021
Picosecond fiber laser was subjected on surface of ductile cast iron to induce graphene-like micro-texture array and enhance the tribological properties. The size of the dimples was regulated in the range of 5 μm–110 μm.
