Effect of carburizing time treatment on microstructure and mechanical propertie...
Boumediri, Haithem; Touati, Sofiane; Debbah, Younes; Selami, Salim; Chitour, Mourad; Khelifa, Mansouri; Kahaleras, Mohamed said; Boumediri, KhaledGas carburizing significantly enhances the surface properties of low-alloy gear steels, resulting in superior micro-hardness, layer thickness, carbon content, and overall mechanical properties. Unlike other thermochemical processes such as nitriding and carbonitriding, which have limitations in core properties and hardening depth, gas carburizing offers unmatched surface hardness, wear resistance, and mechanica...
RF magnetron sputtered Nb–V–N composite coatings for high-temperature self-lubr...
Athmani, Moussa; Kong, FanLin; Ju, Hongbo; Luan, Jing; Zhang, Chengke; Ma, Bingyang; Cavaleiro, Albano; Fernades, Filipe; Fernandes, FilipeEnhancing the tribological properties of hard ceramic coatings for high temperature applications is one of the hot topics in the solid lubricant field. In this paper, a series of Nb–V–N coatings with different V concentrations were deposited using RF magnetron sputtering system, and the crystalline structure, mechanical and tribological properties were investigated. Results showed that the Nb–V–N coatings regar...
Insights into the oxidation resistance mechanism and tribological behaviors of ...
Ju, Hongbo; Athmani, Moussa; Luan, Jing; Al-Rjoub, Abbas M.K.; Cavaleiro, Albano; Yaqub, Talha Bin; Chala, Abdelouahad; Ferreira, FábioIn 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...
