Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ АДГЕЗИИ(54) METHOD FOR DETERMINING ADHESION
Изобретение относитс к способам испытани материалов и касаетс определени адгезии .This invention relates to methods for testing materials and relates to the determination of adhesion.
Известен способ определени адгезии токопровод щей пленки к изол ционной подложке, заключающийс в том, что исследуемый образец размещают в магнитное поле, пропускают через пленку электрический ток, увеличивают напр женность магнитного пол , регистрируют ток и напр женность магнитного пол и определ ют адгезию по величине этих параметров в момент парушепи адгезии.A known method for determining the adhesion of a conductive film to an insulating substrate consists in placing the specimen in a magnetic field, passing an electric current through the film, increasing the strength of the magnetic field, recording the current and intensity of the magnetic field, and determining the adhesion by the magnitude of these parameters at the time of parushepy adhesion.
О нарушении адгезии судили путем фиксации момента отслаивани покрыти , что не всегда совпадает с моментом нарушени адгезии .Violation of adhesion was judged by fixing the moment of flaking of the coating, which does not always coincide with the moment of violation of adhesion.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
Это достигаетс тем, что в процессе испытани регистрируют токовый шум пленки и фиксируют момент его изменени , который принимают за-момент нарушени адгезии.This is achieved by recording the current noise of the film during the test and recording the moment of its change, which is taken as adhesion failure.
Предлагаемый способ осуществл етс следующим образом.The proposed method is carried out as follows.
Образец пз диэлектрика с нанесенной электропровод щей пленкой помещают в магнитное поле, затем через пленку пропускают электрический ток. Образец ориентируют относительно магнитного пол таким образом.A sample of a dielectric die with an applied electrically conducting film is placed in a magnetic field, then an electric current is passed through the film. The sample is oriented relative to the magnetic field in this way.
чтобы на пленку действовали силы отрыва от подложки или сдвига.to act on the film force of separation from the substrate or shear.
В процессе испытани производитс монотонное увеличение напр женности магнитного пол . При этом непрерывно измер етс токовый шум пленки любым известным способом.During the test, a monotonous increase in the intensity of the magnetic field is produced. In this case, the current noise of the film is measured continuously by any known method.
Момент резкого возрастани токового шума соответствует моменту нарушени адгезионного соединени . Фиксиру значение напр женности магнитного пол и тока через пленку в момент возрастани токового щума, по значени м этих параметров оценивают адгезию .The moment of a sharp increase in current noise corresponds to the moment of breakdown of the adhesive joint. Fixed to the value of the intensity of the magnetic field and the current through the film at the time of the current current increase, the adhesion is estimated using the values of these parameters.
