在多弧离子镀和离子渗金属中影响光电温度计测量精度的因素很多，本文通过大量试验、定性和定量的研究了诸因素，得出了校对光电温度计的线性回归方程。在实际测量中，取ε＝０．２能较准确地测量出工件的真实温度。受弧光亮度的影响。光电温度计的指示值高出工件温度６５～７０℃。对于渗 Ｔｉ和渗１Ｃｒ１８Ｎｉ９Ｔｉ的工件表面，其辐射性能相似。对于镀ＴｉＮ和渗Ｔｉ的工件表面利用光电温度计测温时，其指示值相差５℃。透过光学石英玻璃测量时，光电温度计指示值比工件低１７℃，而透过普通玻璃测量时，其指示值比工件温度低６５～８０℃。
In the multi-arc ion plating and ion-permeable metal, there are many factors affecting the measurement accuracy of the photoelectric thermometer. In this paper, a large number of experiments, qualitative and quantitative study of the various factors, obtained a linear regression equation calibration photothermometer. In the actual measurement, taking ε = 0.2 can accurately measure the true temperature of the workpiece. Affected by the brightness of the arc. Photoelectric thermometer indication higher than the workpiece temperature 65 ~ 70 ℃. For infiltration of Ti and infiltration 1Cr18Ni9Ti workpiece surface, its radiation performance similar. For TiN and Ti infiltration Ti workpiece surface thermophotometer temperature, the difference between the instructions of 5 ℃. When measured by optical quartz glass, the indication value of photoelectric thermometer is 17 ℃ lower than that of the workpiece, while the indication value through ordinary glass is 65 ~ 80 ℃ lower than the temperature of the workpiece.
