Surface Wettability of Laser-Induced Al2O3 Ceramic Tools
摘要
利用飞秒激光处理陶瓷刀具表面, 研究了脉冲能量和光斑重合度对其表面浸润性的影响。通过测定激光处理后的氧化铝陶瓷刀片表面的接触角来观察其浸润性。实验结果表明, 飞秒激光可以改变陶瓷材料表面的润湿性能, 通过选择合适的激光能量密度和光斑重合度, 可以制备出超亲水表面和超亲水基切削液的表面。水基切削液在激光处理过的表面上的润湿速度与接触角呈指数衰减关系。
Abstract
The effects of pulse energy and spot overlap ratio on the wettability of ceramic tools processed by femtosecond lasers are investigated. The wettability of the alumina ceramic tools after laser treatment is investigated by measuring the contact angles. The experimental results show that the femtosecond laser can change the wettability of ceramic material surfaces. The superhydrophilic surfaces and the superhydrophilic-based cutting fluid surfaces can be prepared if suitable laser energy density and spot overlap ratio are chosen. The wetting speed of water based cutting fluid on the laser-processed surfaces is exponentially decaying with the contact angle.
