一、前言钛具有重量轻、强度高以及其他一些优点,因此钛及钛合金在航空、空间工业,已日益得到广泛应用,如航空发动机的低压压气机叶片,以及扩散机匣等零件的材料已为钛合金所代替。对这一类形状复杂的钛合金零件的加工,采用电解加工工艺方法,已引起人们普遍注意。钛属于自钝化金属,在电解加工过程中有其特殊性,它的表面极易氧化,形成氧化物薄膜。这层膜的生成与溶解的不均匀性,直接影响电解加工后的表面质量,因此,摸索钛合金的
I. INTRODUCTION Titanium has the advantages of light weight, high strength and other advantages. Therefore, titanium and titanium alloys have been widely used in aviation and space industries. For instance, the materials of low-pressure compressor blades of aeroengines and diffuser casings have been used For the titanium instead. This type of complex shape of titanium parts processing, electrolytic processing technology, has caused widespread attention. Titanium is self-passivated metal, which has its own particularity in electrolytic processing. Its surface is easily oxidized to form oxide film. This layer of film formation and dissolution of non-uniform, a direct impact on the quality of the surface after the electrolytic processing, therefore, explore the titanium alloy
