摘要
针对金属化学蚀刻的工艺技术进行了研究,选择氯化铁为金属蚀刻剂,通过初步试验和正交筛选,确定了蚀刻低碳钢的相对最佳工艺条件:蚀刻液浓度为22.0%,蚀刻温度为45℃,pH为1.0,转速为50r/min(蚀刻液相对流速为3.6m/min).经化学蚀刻后的金属工件具有蚀刻厚度均一,蚀刻面光洁度良好,切面质地一致,精密度高等特点.
In this paper,metal chemical etching techniques were studied.Ferric chloride was selected as metal etchant.Through the initial screening test and orthogonal,the relative optimum etching conditions of low carbon steel were affirmed：the concentration of ferric chloride was 220 g/L,etching temperature 45 ℃,pH=1.0,workpiece speed 50 turns/min（relative flow rate of etching solution is 3.6 m/min）.After chemical etching,the metal work piece has some characteristics： It has identical etching thickness,smooth etching surface,the same cut texture and high precision.
