Abstract

Изобретение относитс  к испытательной технике, предназначено дл  определени  прочности сцеплени  покрыти  с подложкой и позвол ет повысить точность определени  сцеплени  при испытании соединений в которых либо покрытие, либо подложка прозрачнм. На соединение со стороны его прозрачной части воздействуют лазерным импульсом, длительность которого не более 10 с. При прохождении импульса через прозрачный материал либо покрыти , либо подложки он попадает-на границу раздела соединени  и поглощаетс  материалом непрозрачной части. На границе раздела происход т локальный разогрев, испарение и tepMO6 iexa-iitJческа  деструкци  непрозрачного материала , привод щие к возникновению термоупругих напр жений в соединении , под действием которых нарушаС 3 етс  сцепление покрыти  с подложкой на границе их раздела без разрушени  подложки и покрыти . Прочность сцеплени  покрыти  с подложкой определ ют по соотношению площадей участков с нарушенным сцеплением покрыти  с подложкой и участков с ненарушенным сцеплением.The invention relates to a test technique, is intended to determine the adhesion strength of a coating to a substrate, and improves the accuracy of adhesion determination when testing compounds in which either the coating or the substrate is transparent. The connection from the side of its transparent part is affected by a laser pulse, the duration of which is not more than 10 s. When a pulse passes through a transparent material, either of the coating or of the substrate, it hits the interface of the compound and is absorbed by the material of the opaque part. At the interface, local heating, evaporation and tepMO6 iexa-iitJeche destruction of an opaque material occur, resulting in thermoelastic stresses in the joint, under the action of which the coating adheres to the interface without breaking the substrate and coating. The strength of adhesion of the coating to the substrate is determined by the ratio of the areas of areas with impaired adhesion of the coating to the substrate and the areas with undisturbed adhesion.
