The ability of magnetic field distortion (MFD) and magnetic attractive force (MAF) sensors to detect both the inner and outer carburized layers of the furnace tube was investigated in the study. They were employed for quantitative nondestructive evaluation of carburized layer depth in furnace tubes of Cr35Ni45NbMA. It was found that the carburized layer on the outer surface had the dominant effect on the responses of MFD and MAF sensors compared to the carburized layer on the inner surface. Parabolic dependency of the responses of MFD and MAF sensors on the carburized layer at the outer surface was concluded. The accuracy of the proposed sensors was verified by experiments. It was found that MFD sensor was more suitable for the detection of the outer carburized layer of furnace tube than MAF sensor, while PSD obtained by MAF could be used for qualitative evaluation of the depth of inner carburized layer.
