20.500.12556/RUL-168775 Nitrogen alloyed MoSe▫$_2$▫ coatings role of optimized morphology, structure and mechanical properties on diverse environment sliding performance Transition metal dichalcogenide (TMD) coatings are gaining increasing interest among the scientific community as eco-friendly solutions for reducing friction, improving energy conservation, and lowering carbon footprints. N-alloyed MoSe▫$_2$▫ coatings (MoSeN), a subset of TMDs, remain largely underexplored, with no research on their frictional performance across various sliding environments. Herein, an in-depth analysis of DC-magnetron sputtered MoSeN coatings is presented, with N content varying from 0 to 42 at%. Investigation of composition, morphological features, crystal structure, mechanical strength and sliding performance are accessed. Our findings revealed that N additions resulted in increased compactness, amorphous structure and hardness of ∼4.6 GPa, and these improvements remained consistent despite compositional variations. The sliding competency was evaluated under six different conditions, revealing promising results in ambient-air and dry-N▫$_2$▫ atmospheres at room conditions and 100 °C. At 200 °C, the sliding performance in ambient-air was better than dry-N2. Friction coefficient for N-alloyed coatings was relatively close, ranging between 0.03 and 0.06, except for a dry-N▫$_2$▫ environment at 200 °C. Nevertheless, wear rate showed slight variations, with higher values observed in dry-N2 at 100 °C and 200 °C but remained within a specific range of 1–7 × 10▫$^{-7}$▫ mm▫$^3$▫/Nm for all other conditions. This study highlights the potential of MoSeN coatings to be scaled for industrial applications, offering a roadmap for reducing the inherent limitations of PVD sputtering. friction and wear MoSeN coatings TMDs PVD sputtering diverse environment sliding MoSeN premazi zaradi trenja in obrabe TMD PVD naprševanje drsenje v različnih okoljih true false false Angleški jezik Slovenski jezik Članek v reviji 2025-04-24 08:52:58 2025-04-24 08:53:03 2025-08-08 13:42:54 0000-00-00 00:00:00 2025 0 0 14 str. art. 110716 Vol. 209 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.92:620.3 1879-2464 10.1016/j.triboint.2025.110716 234052867 RAZ_Yaqub_Talha_Bin_2025.pdf RAZ_Yaqub_Talha_Bin_2025.pdf 1 5B3008DD9783B38E7269F74370798684 2d1a9d46afa85e46db4b8f9bafb68dfd45e4b7792a070b7f255bb966a4ffcf9f 661bd39c-20dc-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209717 https://www.sciencedirect.com/science/article/pii/S0301679X25002117 1 f718a6d3-20db-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209715 Fakulteta za strojništvo 0 0 0
