脉宽和功率对CuZr非晶材料激光微孔热影响区影响
|
摘要
本文研究工艺参数对CuZr非晶材料激光微孔加工过程中热影响区的影响规律。结果表明,随着脉宽增加或功率增加,热影响区宽度逐渐增加。并简要分析了脉宽、功率对非晶箔材激光微孔加工过程中热影响区的作用机理。
The influence law of process parameters on the heat affected zone during laser micro-hole ma-chining of Cu Zr amorphous material has been studied in the text. The results show that the width of the heat affected zone gradually increases as the pulse width or the power increases. The mechanism of pulse width and power on the heat affected zone during laser micro-hole machining for amorphous foils has been briefly analyzed.
