In order to study the microstructure and improve the quality of Ni35 + TiC cladding layer.The LIBS technology,which has not been fully utilized in laser cladding research,is introduced to study the cladding layer.The main components(Ni,Fe,C) in Ni35 + TiC composite cladding layer were analyzed by LIBS and EDS.the difference of different areas of cladding layer was measured and analyzed.It is observed that there is a good correlation between EDS and LIBS result,while LIBS can measure the distribution of ultra-light elements(C etc.).The results of LIBS and EDS show that the distribution of elements along the depth direction of cladding layer is uneven.In addition,the relationship between the spectral information and the hardness,and the relationship between the spectral line intensity ratio of the elements and the hardness are also analyzed.The results show that the LIBS can qualitatively analyze the uneven distribution of the element content in samples,and it has the advantages of fast analysis speed,no need of vacuum environment and sample preparation,etc.,so as to provide a reference for the evaluation of cladding characteristics in industrial application.
