NEW METHODS OF CONTROL AND DEFECTOSCOPY IN MACHINE BUILDING AND INSTRUMENT CONSTRUCTION

Abstract

Tests on cores of various permeability (from KhVG, Armco, and No. 10 steels) were conducted on a MT-DAZ instrument and confirmed the char-ACTER OF THE DEPENDENCE OF THE INSTRUMENT READINGS ON MAGNETIC PERMEABILITY WHICH WAS ESTABLISHED BY THE MAGNETIC FIELD THEORY. MT-DAZ thickness gages were also used in research to determine the effect of the thickness of a coating of mechanical properties, the efficiency of current output, and the uniformity of the coatings. The electromagnetic MT-DAZ thickness gage favorably differs from other examined instruments by its rather wide measuring range, stability, and accuracy of readings, and its minor dependence on the properties of the parts being measured.
