Beschreibung
Zusammenfassung:	FIELD: electrical engineering. SUBSTANCE: proposed method of determination of adhesion degree of thin metal coating to insulation base is based on measurement of quantity of heat quickly administered to coating and on measurement of quantity of heat remained in coating after some time interval. Ratio of these values characterizes adhesion degree. Eddy current are used for heating of coatings. EFFECT: simplification of method with enhanced reliability of results. Предложен способ определения степени сцепления тонкого металлического покрытия с изоляционным основанием, основанный на измерении количества тепла, быстро сообщенного покрытию, и измерении количества тепла, оставшегося в покрытии, через некоторый интервал времени. Отношение этих значений характеризует степень сцепления. Для нагрева покрытия используются вихревые токи.
