Description

Изобретение относитс  к определению прочностных свойств материалов, а именно к устройствам дл  определени  адгезии покрыти  к подложке. Известно устройство дл  определени  ац гезии методом штифтов, содержащее пластину с коническими отверсти ми, в которы Вставл ютс  штифты Ij. Недостатком этого устройства  вл етс  сложна  технологи  подготовки устройства к испытанию, обусловленна  необходимостью притирки конусных штифтов к отверсти м в пластине. Наиболее близким к цаниому изобретени по технической сущности  вл етс  устройст дл  определени  адгезии, содержащее гхзнование дл  установки образца и захват в виде стакана, заполн емого компаундом з. В таком устройстве стакан расположен иод основанием Однако данна  конструкци  устройства не позвол ет определить адгезию на плоских подложках с высокой степенью точности , так как избыток компаунда, необходимый дл  склеивани  с покрытием, затекает при склеивании в зазор между стаканом и основанием, что не гарантирует необходимой площади отрыва. Кроме того, точность может быть сильно снижена из-за усаоки компаунда при затвердевании. Цель изобретени  - повыщение точности Определени  адгезии. Дл  этого стакан расположен над основанием . Кроме того, между стаканом и основанием установлена герметизирующа  про кладка. На чертеже преоставлено предлагаемое устройство, общий виц. Устройство содержит основание 1 с квадратным пазом 2 дл  размещени  испытуемого образца 3. К основанию 1 при помощи винтов 4 крепитс  прижимной диск 5, на котором установлен армированный стакан 6, заполн емый компаундом. В торцевой части стакана 6 имеетс  канавка 7, на которую наноситс  непол рна  кремнийорганическа  емазка дл  устранени  поетекани  еще не затвердевшего компаунда. Между стаканом 6 и основанием 1 имет- с  герметизирующа  прокладка 8.The invention relates to the determination of the strength properties of materials, namely, devices for determining the adhesion of a coating to a substrate. A device for detecting ac geses by the method of pins is known, which contains a plate with conical holes into which the pins Ij are inserted. A disadvantage of this device is the complex technology of preparing the device for testing, due to the necessity of grinding the tapered pins to the holes in the plate. The closest to the cyanium of the invention according to the technical nature is an adhesion detection device, containing an arm for setting up the sample and a grip in the form of a glass filled with compound h. In such a device, the cup is positioned with iodine base. However, this device design does not allow adhesion on flat substrates to be determined with a high degree of accuracy, since the excess compound required for bonding with the coating flows when gluing into the gap between the cup and the base, which does not guarantee the required area detachment. In addition, the accuracy can be greatly reduced due to the compound hardening. The purpose of the invention is to improve the accuracy of adhesion. For this, the glass is located above the base. In addition, a sealing strip is installed between the glass and the base. In the drawing presented the proposed device, a common Vic. The device contains a base 1 with a square groove 2 for placing the test sample 3. To the base 1 with screws 4 is attached a pressure disk 5, on which is mounted a reinforced cup 6, filled with compound. In the end part of the cup 6 there is a groove 7, on which a non-silicon binder is applied to eliminate the flow of the not yet hardened compound. Between the cup 6 and the base 1, have a sealing gasket 8.
