一、钛合金电解加工的特点钛合金是航空工业中较新型的材料,其用途日盆广泛。由于钛合金的切削加工性较差,因而钛合金零件电解加工的必要性就显得突出了。钛合金虽然在电解加工中可以采用NaCl作电解液,但在常温下加工时零件表面质量很差,当电流密度较低或余量较小时(如小于0.3毫米),加工表面粗糙,易产生波纹度。在邻近表面(即距加工面很近或相连接的非加工面)常出现点蚀。此外,钛合金容易钝化,在
First, the characteristics of titanium alloy electrolysis Titanium alloy is the aviation industry in the newer materials, its use day wide range. Due to the poor machinability of titanium alloys, the necessity of electrolytic processing of titanium alloy parts becomes prominent. Although titanium alloy can be used as electrolyte in electrolysis process, the surface quality of parts is very poor when machining at normal temperature. When the current density is low or the margin is small (for example, less than 0.3 mm), the machining surface is rough and the ripples are easily generated degree. Pitting often occurs in the vicinity of the surface (ie, the non-machined surface close to or connected to the machined surface). In addition, titanium is easily passivated at
