摘要

Supersonic fine particles bombarding (SFPB) is an important way to perform surface nanocrystallization. Harder the material is, higher the jetting particles speed is needed to perform surface nanocrystallization. Equipment with excellent features is the premise to gain the nanostructured layer. SFPB surface nanocrystallization equipment investigated in this paper consist of supersonic jetting gun, robot system, control part and auxiliary part. During the designing and optimizing of Laval nozzle, which is the key component of the supersonic jetting gun, its structure parameters and a lengthened section with micro-divergent angle are designed according to the theory of gas dynamics and numerical simulation analysis of the flow field is conduced by the Fluent software to optimize the configuration of the Laval nozzle. Consequently, the air speed at the exit of the gun is more than 600m/s and the average speed of jetting particles is 320m/s at the distance of 50mm from the exit of the gun. Also, a visual control system is developed which can adjust, detect and manage automatically processing parameters. This equipment can be used to prepare for nanostructured layer with high performance on high hardness surface of component with complex shape and the automatic processing throughout is realized.
