METHOD OF DETERMINING THROUGH POROSITY OF OXIDE COATS OF STEELS Russian patent published in 2003 - IPC

Abstract RU 2196975 C2

FIELD: physico-chemical analysis. SUBSTANCE: method consists in treatment of specimens with and without coats by nickel nitrate solution of 2-5 g/l and 10-4-10-3 Ci/l radionuclides of cobalt -650 continued for 1-2 h followed by flushing sediments by desalted water, measuring residual radioactivity by γ-radiation and calculating the porosity by relationship of activities of specimens with and without coats. EFFECT: enhanced accuracy of measurements at reduced radioactivity of working solutions. 4 tbl
