Embodiment 1
[0034] The Ti / AlTiN / Ti:DLC composite film with high hardness and high wear resistance is deposited by an intermediate frequency reactive magnetron sputtering system, and the target material is a Ti and AlTi alloy target with a purity of 99.9% (Al:Ti=67:33 (atm%) ), the purity of nitrogen and argon is >99.9%, the air pressure in the steel cylinder is greater than 10MPa; the background pressure of the vacuum chamber is less than 3×10 -4 Pa, the cooling water outlet temperature is lower than 25°C, the return water temperature is lower than 40°C, and the revolution speed of the workpiece holder is continuously adjustable within the range of 0-20 rpm. Cleaning of the workpiece to be plated and clamping of the workpiece: Ultrasonic cleaning and dehydration of the workpiece to be plated are carried out with detergent, deionized water, acetone, and absolute ethanol respectively. The cleaning time is 10-20min each time, and the power density is 40W / piece. After drying, transfer to the ...
