(54) СПОСОБ КОНТРОЛЯ СЦЕПЛЕНИЯ ПОКРБ1ТИЯ С ПОДЛОЖКОЙ(54) METHOD OF CONTROL OF COUPLING POKRB1TIYA WITH SUBSTRATE
1one
Изобретение относитс к исследованию качества механических свойств адгезионных соединений и может быть использовано дл оценки сцеплени покрытий с твердым материалом подложки.The invention relates to the study of the quality of the mechanical properties of adhesive joints and can be used to assess the adhesion of coatings to solid substrate material.
Известен способ контрол сцеплени покрыти с подложкой, заключающийс в том, что образец, выполненный из подложки с нанесенным на ее рабочую поверхность покрытием, и эталон подвергают знакопеременным механическим, колебани м, например , с помощью ультразвукового вибратора и довод т амплитуду колебаний до максимального значени , при котором происходит отслоение покрыти от подложки; о качестве покрыти суд т по величине амплитуды ко.цебаний образца при заданной частоте колебаний 1.A known method of controlling the adherence of a coating to a substrate is that a sample made of a substrate coated on its working surface and the standard is subjected to alternating mechanical vibrations, for example, using an ultrasonic vibrator and bring the amplitude of oscillations to a maximum value wherein the coating is peeled off from the substrate; The quality of the coating is judged by the magnitude of the amplitude of the sample emissions at a given oscillation frequency 1.
Недостатком известного способа вл етс сравнительно низка точность, так как практически трудно зафиксировать момент разрушени покрыти , кроме того, применение этого способа ограничено малыми толщинами исследуемых покрытий. Известный способ относитс к методам, при которых происходит разрушение покрыти .The disadvantage of this method is relatively low accuracy, since it is practically difficult to fix the moment of the coating destruction, in addition, the application of this method is limited by the small thicknesses of the coatings under investigation. The known method relates to methods in which the destruction of the coating occurs.
Целью изобретени вл етс повышение точности контрол сцеплени и расширение диапазона его применимости.The aim of the invention is to improve the adhesion control accuracy and expand the range of its applicability.
Цель достигаетс тем, что дл образца и эталона фиксируют параметры внутреннего трени подложки с покрытием, стро т графики зависимостей внутреннего трени от амплитуды колебаний, по которым определ ют максимальную разность амплитудных значений внутреннего трени дл пр мых и обратных колебаний образца и эталона , а по величине этой разности суд т о качестве сцеплени покрыти с подложкой .The goal is achieved by fixing the parameters of the internal friction of the coated substrate for the sample and the standard, plotting the dependencies of the internal friction on the amplitude of oscillations, which determine the maximum difference of the amplitude values of the internal friction for the forward and backward oscillations of the sample and the standard this difference is judged on the quality of adhesion of the coating to the substrate.
Способ осуществл ют следующим образом .The method is carried out as follows.
