| 摘 要： | 以激光熔覆技术为基础，采用激光诱导击穿光谱技术研究不同扫描速度下熔覆样件的硬度与光谱之间的相关性。收集不同硬度样品的光谱数据，提取其中离子与原子光谱线的光谱强度比，与样品的显微硬度做比较。研究表明，基于熔覆层的硬度、激光熔覆的工艺参数以及熔覆层成型差异，不同样品的谱线强度比不同。同一块样品中CrⅡ/CrⅠ的比值可以反应熔覆层不同区域的硬度关系。采用激光诱导击穿光谱技术可以评价熔覆成型质量。

| Abstract: | Based on laser cladding technology, laser-induced breakdown spectroscopy was used to study the correlation between hardness and spectrum of cladding samples at different scanning speeds. The spectral data of samples with different hardness was collected, and the spectral intensity ratio of the ions to the atomic spectrum line was extracted to be compared with the microscopic hardness of the sample. Research results show that the spectral intensity ratios of different samples are different, which is related to the differences in the hardness, the process parameters and the formation of the cladding layer. The ratio of Cr Ⅱ/Cr Ⅰ in the same sample can reflect the hardness relationship of different areas of the cladding layer. The quality of cladding can be evaluated by using laser-induced breakdown spectroscopy technology. |
