Abstract

We demonstrate the possibility of the quantitative multielement analysis of a composite wear-resistant coating (tungsten carbide particles in chromium–nickel matrix) during its synthesis by coaxial laser cladding. The developed probe for the laser-induced breakdown spectrometry (LIBS) was used for the online analysis of the concentration of carbon, tungsten, and nickel in the process of applying a wear-resistant coating. The results of online LIBS measurements agreed closely with the results of the offline analyses using conventional methods such as X-ray fluorescence spectrometry, X-ray spectral electron probe microanalysis, and the combustion infrared absorption method using a LECO gas analyzer.

激光诱导击穿光谱法分析同轴激光熔覆过程中产品的成分

摘要

我们证明了通过同轴激光熔覆合成复合耐磨涂层（铬镍基合金中的碳化钨颗粒）的定量多元素分析的可能性。研发的用于激光诱导击穿光谱仪（LIBS）的探头用于在线分析耐磨涂层中碳，钨和镍的浓度。在线LIBS测量的结果与使用常规方法（例如X射线荧光光谱法，X射线光谱电子探针显微分析和使用LECO气体分析仪的燃烧红外吸收法）的离线分析结果非常吻合。
