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

Luan, Jing (avtor), Ju, Hongbo (avtor)

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.
