Characterization of lubricating oil using ultrasound
(2001-12-01)
This paper presents an ultrasonic method to measure small concentrations of water in lubricating oil. It uses an ultrasonic measurement cell composed by a piezoceramic emitter (5 and 10 MHz), and a large aperture PVDF ...

Estudo tribológico de biolubrificantes com adição de nanopartículas de óxidos (zinco e cobre)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2013-08-02)
Currently, vegetable oils have been studied for bio-lubricants base that fits the new environmental standards. Since, in a world full of finite natural resources, mineral oils bring consequences to the environment due to ...
Multi-scale surface patterning – an approach to control friction and lubricant migration in lubricated systems
(Emerald Group Publishing Ltd., 2019)
Purpose: The paper aims to investigate the possibilities to control friction in lubricated systems by surface patterning, making use of a multi-scale approach. Surface patterns inside the tribological contact zone tend to ...
