초록

This work was carried out for the measurement of vibration and rotation temperature using the optical emission spectroscopy of nitrogen second positive system in the small plasma torch. Among emissions $N_2$ SP systems, the emission of $N_2$ SP(0-0) was so strong. Emission peaks of SP system increased until the position of 12.5[mm] from the end of plasma torch, after that it decreased. However, vibration temperature decreased from 1540[K] to 1000[K] at the position of 12.5[mm]. In addition, rotational temperature was about 400[K] at the position of 10[mm] and it increased a little as much of 420[K] at 12.5[mm]. Consequently, the plasma torch discussed in this work is possible to apply in the surface treatment process under the low temperature.
