Beschreibung
Zusammenfassung:	The invention discloses a turbocharger sealing ring subjected to laser surface texturing and a machining method. After laser surface texturing, arc-shaped micro-concave cavities different in diameter and depth are formed in the left end face, the right end face and the inner circle surface of the turbocharger sealing ring and are distributed densely in a well-arranged manner. The machining method of the turbocharger sealing ring comprises the following steps that a surface fluid lubrication theoretical model of the turbocharger sealing ring is built to determine the diameters, depths and area occupancy rates of the arc-shaped micro-concave cavities in the left end face, the right end face and the inner circle surface with the optimal lubrication friction reduction effect through numerical calculation; and then a diode pumping Nd:YAG laser device is selected, under a laser machining graphic software interface, the geometrical parameters and distribution state of the arc-shaped micro-concave cavities are input, and laser surface texturing machining is carried out on the left end face, the right end face and the inner circle surface of the turbocharger sealing ring through a single pulse same-point interval repeated machining technology.
