چکیده انگلیسی
Ta-Ag immiscible alloy film shows potential application as a protective coating during sliding contact at high temperatures. In this study, Ta-Ag films were deposited on carbon steel by DC magnetron sputtering at the ambient temperature. The microstructures of Ta-Ag films were adjusted by controlling working pressures (0.2-0.8â¯Pa) and sputtering powers of tantalum (90â¯W-100â¯W). The nano-crystalline α-Ta is deposited at the working pressure of 0.2 and 0.4â¯Pa while the amorphous Ta is produced at 0.6 and 0.8â¯Pa for Ta90-Ag8 films. The hardness and elastic of Ta-Ag films decreases with the increase of sputtering pressure. The friction coefficients of nanocrystalline Ta90-Ag8 films deposited at 0.2 and 0.4â¯Pa are lower than that of amorphous films deposited at 0.6 and 0.8â¯Pa from RT to 600â¯Â°C. A friction coefficient of about 0.32 and low wear rate (1.6â¯Ãâ¯10â5â¯mm3/Nm) is obtained for the Ta90-Ag8 film deposited at 0.2â¯Pa at 700â¯Â°C.
