The relation between the descaling degree and the exo-electron emission characteristics of sandblasted steel was studied. The total emission counts in glow curve from room temperature to 250°C were found satisfactorily reproducible with the accuracy of about ±10% for the specimen blasted under the given condition. The total counts of the 100% descaled specimen differ from those of 50% descaled specimen by the ratio of about 5 to 3. Personal empirical decision for the descaling egree was found rather unreliable if compared with the exo-electron measurement.
