摘　　要：基于犁切-挤压加工方法,在2mm厚的铜板表面进行交错犁切-挤压加工,以加工具有孔-槽特征的沸腾强化结构。试验发现犁切-挤压的深度和进给量是影响结构成形的主要加工参数,以0.8mm和1.2mm为一次犁切-挤压的深度和进给量,并以1.68mm为二次犁切-挤压进给量时,加工出具有孔-槽特征的沸腾强化结构。Using ploughing-extrusion technology, a pore-groove enhanced boiling structure is formed on the surface of copper plate with thickness of 2 mm through staggered ploughing-extrusion process. Study showed that the ploughing-extrusion deep and feed were the main parameters which affected the formation of the structure, and a pore-groove enhanced boiling structure is formed by using 0. 8mm and 1.2mm as the first plough-extrusion depth and feed,and 1.68mm as the second ploughing-extrusion feed.
