摘　　要：为了在脆性难加工材料上制备结构化鱼鳞表面,首先提取了鱼鳞表面的拓扑特征,建立了鱼鳞单元的表面模型,并基于鱼鳞模型进行搭接,得到结构化鱼鳞表面;然后根据微磨料气射流加工原理,分析了气射流加工拓扑鱼鳞实验的可行性与影响结构化鱼鳞表面形貌的重要工艺参数;最后采用单因素实验法对重要加工参数进行实验分析,得到了较好的拓扑鱼鳞表面单元,并以此进行排布得到结构化表面。研究结果表明,微磨料气射流加工结构化拓扑鱼鳞表面较为合理的工艺参数组合是加工时间为10 s、气射流加工压力为0.5 MPa、靶距离为10 mm以及射流角度为30°,在此工艺条件下,鱼鳞表面的形态和尺寸可能会受到一定的影响,但鱼鳞表面的拓扑属性保持不变。To prepare structured fish scale surfaces on brittle and difficult-to-process materials,the topological features of fish scale surfaces are first extracted,and a surface model of fish scale units is established.This fish scale model is then used to construct the structured fish scale surface.Next,based on the principle of micro-abrasive air jet processing,the feasibility of air jet processing for topological fish scale experiments and the important process parameters affecting the morphology of the structured fish scale surface are analyzed.Finally,using the single-factor experimental method,the important processing parameters are experimentally analyzed to obtain a better topological fish scale surface unit,and the structured surface is arranged accordingly.The research results show that a reasonable combination of process parameters for micro-abrasive jet machining of structured topological fish scale surfaces includes a machining time of 10s,a machining pressure of 0.5 MPa,a stand-off distance of 10 mm,and a jet angle of 30°.Despite the potential for certain effects on the morphology and size of the fish scale surface,the topological properties of the fish scale surface remain unchanged using the proposed machining method.
