Fretting degradation in large flat-on-flat contact under oil lubrication: Effect of displacement amplitude
(09 / 2025)
articleFretting degradation of self-mated quenched and tempered steel was studied by varying loading conditions via imposed tangential displacement amplitude in oil-lubricated flat-on-flat contact. Detailed microscopic characterization ... -
Fretting induced friction behavior in flat-on-flat contact with cast iron and steel
(2020)
DiplomityöCyclic loading of a combustion engine may generate microscopical reciprocating movement in its joints. This motion between two surfaces is called fretting, a harmful phenomenon which might lead to critical damage or failure. ... -
Fretting Induced Friction, Wear and Fatigue in Quenched and Tempered Steel
Tampere University of Technology. Publication : 1392 (Tampere University of Technology, 2016)
ArtikkeliväitöskirjaFretting stands for reciprocating surface sliding with a typical sliding amplitude of a few tens of micrometres and a potential outcome of fretting fatigue and fretting wear. Fretting efficiently nucleates surface cracks, ... -

Fretting test rig with variable normal force
(10 / 2020)
articleFretting is small amplitude reciprocating sliding between surfaces, and it may quickly causes surface cracks, which can continue growing under cyclic loads, until the structure breaks entirely as a result of the fretting ... -
Friction and temperature mapping of environmentally acceptable gear oils
(11.12.2020)
articleIn recent years, environmental issues have raised the demand to protect the environment against the pollution caused by the uncontrolled spillage of lubricating oils. One solution is using Environmentally Acceptable ... -

Friction Transfer of Teflon to Template the Growth of Organic Semiconductors
(2015)
DiplomityöOrganic field effect transistors (OFET) based on the latest generation of p-type organic semiconductors (DNTTT, C10-DNTT) display excellent characteristics, with charge transport mobility of up to 10 cm2/Vs. These materials ... -
Friction, abrasion and crack growth behavior of in-situ and ex-situ silica filled rubber composites
(2020)
article<p>The article focuses on comparing the friction, abrasion, and crack growth behavior of two different kinds of silica-filled tire tread compounds loaded with (a) in-situ generated alkoxide silica and (b) commercial ... -
Frictional performance of chemically modified cottonseed-based fossil-free biolubricant oil in a sliding tribopair
(2023)
articleIn this study, the tribological properties of a green lubricant synthesized from cottonseed oil through a two-step transesterification process are investigated, with a specific focus on the maximum throughput of the second ... -
