摘要
为探究水导激光加工后TC4钛合金材料表面形貌特征,利用Synova公司生产的LCS305水导激光加工设备对2 mm厚TC4钛合金轧制板材进行切割试验。采用CCD工业体式显微镜、扫描电子显微镜及光学轮廓仪对切割表面形貌进行了分析。试验结果表明,水导激光加工后的TC4钛合金切割表面会产生横向条纹,且横向条纹数目与水导激光扫描周次相同;TC4钛合金切割表面根据特征的不同可以分为4种区域,即隆起区、凹陷区,碎石区、波纹区,并对各区域的形貌及产生机制进行初步分析。
This study investigates the surface morphology characteristics of TC4 titanium alloy material subjected to water jet-guided laser processing.Cutting tests were performed on 2 mm thick TC4 titanium alloy rolled plates using LCS305 water jet-guided laser processing equipment from Synova.The surface morphology of the cuts was examined using a CCD industrial microscope,scanning electron microscope,and optical profilometer.The experimental results show that the cross-section of TC4 titanium alloy processed by water jet-guided laser will produce transverse stripes,and the number of transverse stripes is the same as the scanning cycle of water jet-guided laser.The cutting surface of TC4 titanium alloy can be divided into four kinds of regions according to the different characteristics,namely:uplift zone,depression zone,crushed stone zone and ripple zone.The morphology and generation mechanism of each region are preliminarily analyzed.
