Abstract

The invention relates to a processing method of a compound scale texture. The processing method is characterized in that a processing object is fixed to a fixture of an industrial robot; a laser whichis fixed to a precise optical vibration isolation platform adopts a high-power Q-switching Nd: YAG laser, and the shape of light spots is rectangular; laser beams emitted by the laser through a lightguiding device irradiate the surface of the processing object to perform micrometer-scale texture processing; and the surface of the processing object is covered with nanometer particles evenly, andthe nanometer particles are embedded in the surface of a material under the action of laser shock pressure and removed through a megasonic cleaning method to form a nano-scale surface texture. According to the processing method of the compound scale texture, the deficiencies that the texture scale of an existing anti-attrition technology is single and the anti-attrition effect is limited are overcome.

Description

technical field [0001] The invention relates to a method for processing composite scale textures through laser shock micro-modeling technology and nano particles, and belongs to the technical field of surface lubrication. Background technique [0002] There are various forms of friction pairs in mechanical systems. These friction pairs not only affect the working performance and operating efficiency of mechanical systems, but also determine their service life. According to statistics, wear caused by friction is the most important cause of mechanical failure, and about 80% of parts are damaged due to wear. Therefore, controlling friction, improving lubrication and reducing wear has become an urgent need to save energy and raw materials, and comprehensively improve the operating efficiency and service life of mechanical systems. [0003] The traditional theory of tribology holds that the smoother the two surfaces in contact with each other, the less the amount of wear will be...
