Abstract: Surface micro-texture demonstrates outstanding performance in lubrication and drag reduction, and is
extensively utilized in areas such as mechanical seal, cylinder liner-piston ring, bearing lubrication, tool drag reduction
and others. With the continuous enhancement of the power level of aerospace electromechanical servomechanism and
the increasingly severe service environment, the friction performance between the slide valve pairs, which is the key
components of the servo valve where motion contact occurs is gaining growing significance. The sliding interface of the
slide valve pairs of the servo valve has emerged as the primary factor influencing the precise random movement of the
servo valve in accordance with the system command signal. There exists sliding friction between the valve core and the
valve sleeve, featuring a small contact area, a short reciprocating distance and a high friction frequency. Hence, the
