This invention relates to a method for predicting the wear performance of aluminum alloy surfaces using self-lubricating composite ultrasonic shot peening. The method first pre-treats the aluminum alloy surface, then textures the surface using laser processing, fills it with a self-lubricating material, and finally performs ultrasonic shot peening to form a mechanically interlocking structure that enhances the bonding strength of the filler layer. Ultrasonic shot peening creates a fine-grained strengthening layer and a residual compressive stress field on the substrate surface, significantly improving surface hardness and fatigue resistance. Simultaneously, this invention provides a wear performance prediction method based on ABAQUS simulation. By simulating the ultrasonic shot peening process using DEM-FEM coupling, a fretting wear model is constructed, and energy wear theory is used to predict the friction coefficient and wear rate. This method achieves four benefits for aluminum alloy surfaces: lubrication and friction reduction, mechanical interlocking, surface strengthening, and fatigue resistance. It can also predict wear performance in advance, guide process optimization, significantly improve R&D efficiency, and reduce experimental costs.

This utility model discloses an internal oil-filling structure for a sintering base, including an oil-filling assembly.

An oil-filling pipe is detachably installed on one side of the oil-filling port, and the size of the oil-filling pipe is adapted to the oil-filling port. This utility model allows for convenient injection of lubricating oil into the sintering base shell by setting up the oil-filling assembly.

Simultaneously, the heat conduction effect allows the lubricating oil to carry away the heat generated by friction during its flow, transferring the heat to the external environment through oil circulation, helping to reduce the internal temperature of the product and achieving rapid heat dissipation. This changes the previously cumbersome operation process, eliminating the need for disassembly to add lubricating oil and effectively preventing the entry of impurities.
