...Zhe Yang; Zhongyi He; Liang Qian; Laizhao Ouyang; Jian Liu; Lili Li; Yayu Dong; Liping Xiong; Qiyang Long Purpose The purpose of this study is to evaluate the tribological properties of modified molybdenum disulfide (MoS₂) nanoparticles as rapeseed oil ( RO ) additives under different...

... lubricants on the surface wear morphology, crack propagation and fatigue damage of the wheel rail were systematically evaluated. Findings Experiments have shown that both MoS₂ and graphite based solid lubricants can significantly suppress macroscopic wear. Under lubrication conditions...

...Lingrui Cai; Ziyi Li; Sang Xiong Purpose Surface modification of MoS₂ was carried out to improve its tribological properties. This paper aims to reveal that by precisely controlling the modifier type and addition amount, a significant reduction in the friction coefficient and enhanced...

.../approach In this study, UHMWPE matrix composites with different content of MoS₂ were prepared and the tribological performance of the GCr15/composites friction pair in various sliding speeds (0.025–0.125 m/s) under dry friction conditions were studied by ball-on-disk tribology experiments...

...Peiwen Sun; Jianwei Yang; AiHua Zhu; Zhongshuo Hu; Jinhai Wang; Fu Liu; Xiaohui Wang Purpose The CL60 steel wheels of subway vehicles operating on specific lines require frequent refurbishment due to rapid wear and tear. Considering this issue, MoS₂-based and graphite-based solid...

...Kunhong Hu; Yan Miao; Ziyan Lu Purpose This paper aims to explore the preparation and tribological performance of MoS₂ nanoparticles supported on fly ash (FA) microparticles. Design/methodology/approach FA was activated by NaOH, oleic acid and HCl to obtain three modified FA samples...
