The principle and application of the kryptonated technique for temperature measurement was described. Taking the surface working temperature of CO2 compressor piston ring as a example, the measuring results by means of kryptonated technique was introduced in this paper. The temperature measurement range of this technique is between room temperature and 1000℃, the precision is ± 5℃. The kryptonated component was prepared with diffuse method. The application of this technique is as follows: embedding the component into test parts and operating at least for 15 minutes under working conditions, then removing component and putting it into the heating stove, recording the heat temperature and the radiation in tensity of kryptonated component under each temperature, calculating turning point of radiation intensity decreasing with graphic method, the temperature corresponding to this turning point is the highest surface working temperature of this part under the given condition. The results shown that the method for measuring surface temperature of solid lubrication by means of embedded kryptonated technique is feasible. It's a temperature measurement technigue in situ and can be used in measuring the surface working temperature of different friction pairs.
