Distribution of porosity in sintered permeable materials by an eddy current method

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The proposed method for the nondestructive determination of the distribution of porosity over the cross section of a specimen is based on eddy current measurements of electrical conductivity. Data on the distribution of porosity over the cross section of a specimen obtained metallographically with the aid of a Quantimet-720 television microscope and by the eddy current method match closely (error in the determination of porosity does not exceed 4.2%). The method described can be recommended for the control of the quality of parts in series production.
