The use of artificial intelligence in tribology—a perspective
(MDPI, 2021)
Artificial intelligence and, in particular, machine learning methods have gained notable attention in the tribological community due to their ability to predict tribologically relevant parameters such as, for instance, the ...
Effect of macromolecule orientation on the coeficient of friction of thermoplastic polymers
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em Engenharia MecânicaUTFPR, 2019-12)
During a previous study, focused on the tribological characteristics of PTFE (polytetrafluoroethylene), the possibility that the orientation of carbonic macromolecules might have influence upon the tribological properties ...

Influence of the Gas Pressure of Plasma Nitriding on the Structural, Mechanical and Tribological Surface Properties of AISI 316L
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2019-01-01)
In this paper, the influence of gas nitriding (80% H-2-20% N-2) pressure (between 3 and 7 Torr) on the modification of surface properties of AISI 316L stainless steel is examined. The structural, mechanical, tribological ...
Tribological properties of graphene and boron-nitride layers: A fully atomistic molecular dynamics study
(2012-12-05)
Graphene has been one of the most important subjects in materials science in the last years. Recently, the frictional characteristics of atomically thin sheets were experimentally investigated using atomic force microscopy ...
Tribology of hard coating alloys deposited by thermal methods: Applications to industrial components
(Elsevier Science Sa, 2008-12)
In most of seamless tube making industries, the useful life of mandrels for rotary forging is less than 350 perforation events; though in some cases, the tool may last longer than 1000 perforations. Being the first of a ...
Effects of high temperature plasma immersion ion implantation on wear resistance of Ti-Si-B sintered alloys
(2013-08-15)
Although titanium and its alloys own good mechanical properties and excellent corrosion resistance, these materials present poor tribological properties for specific applications that require wear resistance. In order to ...
