Experimental determination of the spectral absorption coefficient of a plasma-erosion torch on the surface of carbon-bearing materials

Abstract In the work, the spectral coefficient of the plasma-erosion torch on the glassy carbon surface was determined on the basis of the Wien violation law and the experimental determination of the brightness temperature. The possibility of using a micropyrometer to determine the spectral factor c...

Summary:Abstract In the work, the spectral coefficient of the plasma-erosion torch on the glassy carbon surface was determined on the basis of the Wien violation law and the experimental determination of the brightness temperature. The possibility of using a micropyrometer to determine the spectral factor can be a plasma-erosion torch, with the help of which (spectral absorption coefficient) it is rather quick to determine the thermodynamic temperature of the plasma-erosion torch.
