| 摘 要： | 为了实时监测和控制激光除锈过程,采取利用光电二极管检测等离子体的光强信号,并用示波器将其转换为电压信号的方法,得到了等离子体峰值电压信号随激光能量、激光冲击次数变化的曲线图.结果表明,根据等离子体电压信号峰值大小变化趋势可以确定除锈阈值,也可以判断激光除锈是否干净.

| Abstract: | In order to monitor and control laser derusting process in real time,the light intensity of plasma was detected with a photodiode,and the light signal was transformed into voltage signal with an oscilloscope,so that the curves of peak voltage versus laser energy and laser impact number were obtained.The results show that the derusting threshold and whether the metal surface is cleaned clearly can be determined according to the tendency change of the peak voltage signal. |
