Keyword激光诱导击穿光谱技术 时间演化 高合金钢

激光诱导击穿光谱技术(LIBS)具有无需样品制备,原位快速分析,可进行实时控制的特点使其在钢铁冶炼控制中具有巨大的实际应用价值。本文以波长为1 064 nm的Nd∶YAG调Q固体激光器为激发光源,CCD为探测器,高合金钢GBW01605—01609系列为样品,在建立的LIBS实验装置上研究激光与合金钢之间的相互作用。系统地研究了观测距离、激光能量对高合金钢样品中激光诱导击穿谱特性的影响,并分析了LIBS信号的时间分辨特性,确定了将LIBS用于合金钢微量元素定量分析时的最佳实验条件。

Other Abstract

The laser-induced breakdown spectroscopy(LIBS) technique is a fast,non-contact method with no need for any sample preparation,and can be carried out under various atmospheric conditions.These properties make LIBS applicable to process control in metallurgy.In the present paper,a series of high alloy steel GBW01605—01609 samples were determined by laser induced plasma spectroscopy,based on a Nd∶YAG Q-switched solid laser with wavelength 1 064 nm as an excitation source and CCD as detector.Experimental study on the interaction between laser and high alloy steel samples was completed.The effects on LIBS in high alloy steel such as observation distance and laser power density were systematically studied.The time-resolved spectrum of LIBS was also investigated.The optimum experiment conditions for the application of LIBS to the trace analysis in high alloy steel were obtained firstly.
