Friction coefficient and wear mode transition in micro-scale abrasion tests
(2011)
The purpose of this work was to conduct ball-cratering wear tests to monitor both normal and tangential forces. Balls of 52100 steel, a specimen of H10 tool steel and an abrasive slurry prepared with silicon carbide particles ...
Neural networks to improve mathematical model adaptation in the flat steel cold rolling process
(2010-12-01)
In the flat steel cold rolling process, real-time controllers get their reference values (setpoints) using a mathematical model. Such a model is carried out at the process optimization level of the plant automation ...
Avaliação do desempenho tribológico de graxas e modificadores de atrito a base de água utilizados no contato roda-trilho em um ensaio disco sobre disco
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-12-09)
The tribological phenomena on the wheel-rail interface is complex. This interface performance regarding friction and wear impacts fuel consumption, wheels’ and rails’ lifespan, which are among the highest operating costs ...

Tribological behavior of PVD multilayer coatings in dry rolling-sliding contact
(Universidade Federal de São Paulo, 2023-01-10)
Tooth contacts in gear drives are usually lubricated with fluid lubricants, such as oil or grease.
However, extreme operating conditions with high pressure and temperature fluctuations cause
liquid lubricants to lose ...
