利用双色红外测温仪研制了一套温度测量系统。在激光测距过程中实现了实时跟踪和定点测量。研究了送粉速率、激光束扫描速度、激光功率、光斑直径、保护气体流量和送粉位置等激光工艺参数对熔池温度的影响。讨论了单层熔覆层厚度的控制方案，建立了熔池温度与熔覆层厚度的关系。(c)2007 Elsevier B.V.保留所有权利。
A temperature measurement system has been developed by using a two-color infrared thermometer. The real-time tracking and fixed-point measurement were achieved during the LRF process. The influences of laser processing parameters on the temperature of molten pool was investigated, such as powder feed rate, scanning velocity of laser beam, laser power, spot diameter, shielding gas flow rate and powder feeding position. The control scheme of the single layer thickness was discussed and the relationship between the molten pool temperature and the cladding thickness was build. (c) 2007 Elsevier B.V.
