Insights into the oxidation resistance mechanism and tribological behaviors of ...
Ju, Hongbo; Athmani, Moussa; Luan, Jing; AL-Rjoub, Abbas; Cavaleiro, Albano; Yaqub, Talha Bin; Chala, Abdelouahad; Ferreira, Fabio; Fernandes, FilipeIn the last decades, vanadium alloyed coatings have been introduced as potential candidates for self-lubrication due to their perfect tribological properties. In this work, the influence of V incorporation on the wear performance and oxidation resistance of TiSiN/CrN film coatings deposited by direct current (DC) reactive magnetron sputtering is investigated. The results show that vanadium incorporation signifi...
Vacuum Tribological Properties of W-S-N Coatings Synthesized by Direct Current ...
Yaqub, Talha Bin; Yaqoob, Khuram; Mukhtar, Amir; Fernandes, Filipe; Bondarev, Andrey; Ferreira, Fabio; Al-Rjoub, Abbas; Cavaleiro, AlbanoThis work deals with the investigation of the tribological performance of DC magnetron sputteredW-S-N coatings under vacuum atmosphere, as part of the exploration of multi-environment sliding properties of W-S-N solid lubricants. This study is part of the systematic testing of W-S-N solid lubricants in different environments, especially vacuum, which is often ignored. The trend is to test sliding properties in ...
Real-time evaluation system for top Taekwondo athletes: project overview
Cunha, Pedro; Barbosa, Paulo; Ferreira, Fabio; Fitas, Carlos; Carvalho, Vitor; Soares, FilomenaAssessing athletes' performance is a constant challenge for coaches, whatever the sport is. In some sports there are no technological solutions to assist coaches in this task. This is the case of Taekwondo, where currently the methods used are mainly manual. Following this trend, this article presents the work developed in a PhD project whose main objective is the development of a friendly and low-cost system f...
