Изобретение относитс к испытательной технике и может быть использовано при определении прочности сцеплени покрытий с подложкой.The invention relates to a testing technique and can be used in determining the adhesion strength of coatings to a substrate.
Известен способ определени прочности сцеплени покрыти с подложкой, заключающейс в том, что на поверхность подложки устанавливают обойму с коническим отверстием, обращенным к подложке мен.ьшим диаметром, нанос т покрытие на поверхность подложки в зоне обоймы и пойле отверждени покрыти прикладывают отрывающую нагрузку к обойме до разрушени сцеплени покрыти с подложкой, по величине которой суд т о прочности сцеплени llНедостатком способа вл етс ограниченна область его использовани , так как он не позвол ет определ ть прочность сцеплени тонких покрытий, нанесенных на поверхность изделий.A method is known for determining the adhesion strength of a coating with a substrate, which consists in placing a holder with a tapered bore facing the substrate with a smaller diameter on the surface of the substrate, applying a coating to the surface of the substrate in the area of the holder and pulling the coating to apply a tearing load to the holder destruction of the adhesion of the coating to the substrate, the magnitude of which is judged on the adhesion strength. The disadvantage of the method is its limited range of use, since it does not allow determining adhesion of thin coatings applied to the surface of products.
Наиболее близким по технической сущности к изобретению вл етс способ определени прочности сцегшени покрыти с подложкой, заключающийс в том, что ма поверхность испытуемого покрыти устанавливают с адгезива отрывной элемент и после отверждени адгезива прикладывают кThe closest to the technical essence of the invention is a method for determining the strength of a coating with a substrate, consisting in that the surface of the test coating is installed on the surface of the adhesive with a tear-off element and after curing the adhesive is applied to
отрывному элементу нагрузку до отрыва покрытг , по величине которой суд т о прочности сцеплени j.The detachable element has a load up to the separation of the coat, according to the magnitude of which the strength of j is judged.
Недостатком этого способа вл етс низка точность определени прочности сцеплени покрыти с подложкой, так как отверждение адгезива, нанесенного на покрытие после установки на него отрывного элемента, проис10 ходит неравномерно из-за отсутстви выхода продуктов испарени адгезива иг-под центральной поверхности отрывного элемента после отверждени гдгезива по кра м.The disadvantage of this method is the low accuracy of determining the adhesion strength of the coating to the substrate, since the curing of the adhesive applied to the coating after installing the tear-off element on it occurs unevenly due to the lack of yield of the product of evaporation of the adhesive ig-under the central surface of the tear-off element after curing the adhesive on land m

Целью изобретени вл етс повышение точности определени путем обеспечени равномерности отверждени адгезива .The aim of the invention is to improve the accuracy of determination by ensuring uniform curing of the adhesive.
Дл достижени этой цели ИСПОЛЬ20 ЗУЮТ прокладку из пористого материала , которую размещают между покрытием и адгеэивом.To achieve this goal, the ISPOL20 SOUGH gasket of porous material, which is placed between the coating and adhesive.
Способ осуществл ют следующим образом .The method is carried out as follows.
