摘要：Aluminum alloy is one of the most widely light structural materials in the aviation manufacturing industry. The fatigue strength and service life of workpiece can be effectively increased with the improvement of wear resistance. The surface quality of 7050 aluminum alloy under different static pressure (200N-1200N) is obtained by ultrasonic rolling. The effect of static pressure on the friction and wear properties of aluminum alloy surface in ultrasonic rolling process were studied by end surface friction and wear experiment, and the micro-morphology of wear surface was analysed by the super depth microscope. The research showed that the wear resistance of the material surface can be effectively elevated by ultrasonic rolling. Wear degree and wear coefficient of the material were the best, and wear resistance can be improved about 1.5% when static pressure was 600N.
