钛和钛合金（例如，Ti6Al4V）在航空航天和汽车工业中的应用越来越多，并且还在各种应用中用作医疗植入材料。电火花线切割加工是一种重要的特种加工工艺，广泛应用于包括钛合金在内的各种复杂形状难加工材料的加工。这一过程实质上是一个热过程，本文研究了所产生表面的性质。据观察，更均匀的表面特性，获得与涂层丝电极。在对表面特性影响较大的脉冲间隔时间、脉冲宽度、注射压力、丝速和丝张力等参数中，脉冲间隔时间是最敏感的参数。
Titanium and titanium alloys (e.g., Ti6Al4V) are increasingly used in aerospace and automotive industries, and also used as medical implant material in wide variety of applications. Wire-electro discharge machining (WEDM) is an important non-traditional machining process, widely used for machining a variety of difficult-to-machine materials including titanium alloys with intricate shapes. The process is essentially a thermal process and the nature of surface produced is studied in this paper. It is observed that more uniform surface characteristics are obtained with coated wire electrode. Among the parameters such as time between two pulses, pulse duration, injection pressure, wire speed and wire tension that have more influence on the surface characteristics, the time between two pulses is the most sensitive parameter.
