20.500.12556/RUL-168741 Design and magnetron sputtering of nanomultilayered W▫$_2$▫N/Ag-SiN▫$_x$▫ microstructural insights and optimized self-lubricant properties from room temperature to 500 °C Novel multilayered films were engineered by integrating W▫$_2$▫N and Ag-SiN▫$_x$▫ layers in a multilayer structure to obtain improved hardness and tribological properties. The films were fabricated by alternating magnetron sputtering, depositing 40 nm layers of W▫$_2$▫N with varying thickness of Ag-SiN▫$_x$▫ layers varying in thickness from 4 to 20 nm. The effect of the increase thickness of the Ag-SiN▫$_x$▫ layers in the films microstructure and tribological properties were accessed. Tribological experiments were conducted at room temperature (RT), 500 °C, and RT-500 °C cycling conditions. The results revealed the production of a multilayered structure comprising single fcc-W▫$_2$▫N layers interspersed with dual-phase layers consisting of fcc-Ag and amorphous SiN▫$_x$▫ phases. Tribological results indicated an improvement in the tribological performance with increase thickness of the Ag-SiN▫$_x$▫ layer up to 12 nm. The tribo-synergistic/combined action of both W▫$_2$▫N and Ag-SiN▫$_x$▫ layers, along with the presence of layered lubricant tribo-phases of WO▫$_3$▫ and Ag▫$_2$▫WO▫$_4$▫, showcased the pivot role in reducing friction and enhancing wear resistance. The optimized multilayered film, featuring a 12 nm Ag-SiN▫$_x$▫ layer, demonstrated exceptional tribological properties under temperature-cycling from RT to 500 °C. magnetron sputtering W▫$_2$▫N/Ag-SiN▫$_x$▫ multilayered films Ag-SiN▫$_x$▫ layer thickness mechanical properties tribological properties magnetronsko razprševanje večplastni filmi W▫$_2$▫N/Ag-SiN▫$_x$▫ debelina sloja Ag-SiN▫$_x$▫ mehanske lastnosti tribološke lastnosti true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-22 13:31:42 2025-04-22 13:31:46 2025-04-23 04:01:57 0000-00-00 00:00:00 2024 0 0 Str. 39226-39234 issue 20, part B Vol. 50 October 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.21 1873-3956 10.1016/j.ceramint.2024.07.292 233456387 RAZ_Luan_Jing_2024.pdf RAZ_Luan_Jing_2024.pdf 1 97EF38C95817F37A591C728109F592A2 8bd9551be9ce7a417c2cddb9a43c39854c0bb0acb48b89e54113c6eae950f23d 76fea71e-1f6c-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209641 https://www.sciencedirect.com/science/article/pii/S0272884224031973?via%3Dihub 1 3c9938e5-1f6c-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209640 Fakulteta za strojništvo 0 0 0
