(54) ОБРАЗЕЦ ДЛЯ ОПРЕДЕЛЕНИЯ АДГЕЗИИ ПОКРЫТИЯ К ОСНОВНОМУ МАТЕРИАЛУ(54) SAMPLE FOR DETERMINATION OF THE ADHESION OF THE COATING TO THE BASIC MATERIAL
(57)Изобретение относитс к испытательной технике, предназначено дл определени адгезии покрыти к основному материалу при испытании обвазцов и позвол ет повысить точность определени путем учета изгибающих напр жений в зоне контакта покрыти со штифтом. Образец выполн ют в виде П-образной подложки-скобы 1, штифта- i параллелепипеда 2,размещенного между стойками 3 и 4 скобы 1 и шарнирно св занного с ее полкой 5, и покрыти 6, нанесенного на общий торец подложки и штифта. Разрушающую нагрузку Р ПОД действием которой штифт 2 поворачиваетс и постепенно отрьша- етс от покрыти 6, прикладьшшот к противоположному шарниру 7 концу штифта 2. Измер ют величину разрушающей нагрузки в различных точках шири- д ны А покрыти 6 и по известной форму- ле определ ют величину адгезии покрыти 6 к основному материалу штифта 2. 1 ил.(57) The invention relates to a test technique, is designed to determine the adhesion of a coating to a base material when testing obvaztsov and allows to increase the accuracy of determination by taking into account the bending stresses in the zone of contact of the coating with the pin. The sample is made in the form of a U-shaped support-bracket 1, pin-i of parallelepiped 2, placed between the uprights 3 and 4 of the bracket 1 and pivotally connected to its shelf 5, and the cover 6, applied to the common end of the substrate and pin. Breaking load P UNDED, by which pin 2 rotates and gradually detaches from cover 6, applied to the opposite hinge 7 end of pin 2. Measure the value of breaking load at different points of width A of cover 6 and determine from a known formula adhesion value of the coating 6 to the main material of the pin 2. 1 sludge.

Изобретение относитс к испытательной технике, а именно к образцам дл определени адгезии покрытий к основным материалам.The invention relates to a testing technique, namely to samples for determining the adhesion of coatings to base materials.
Целью изобретени вл етс повышение точности определени адгезии покрыти к основному материалу путем учета изгибающих напр жений в зоне контакта покрыти со штифтом.The aim of the invention is to improve the accuracy of determining the adhesion of the coating to the base material by taking into account the bending stresses in the zone of contact of the coating with the pin.
На чертеже показана схема предлагаемого образца.The drawing shows the scheme of the proposed sample.
Образец вьтолнен в виде П-образной подложки-скобы 1, штифта-параллелепи- педа 2, размещенного между стойками 3 и 4 скобы 1 и шарнирно св занного с ее полкой 5, и покрыти 6, нанесенного на общий торец подложки-скобы 1 и штифта-параллелепипеда 2. The sample is made in the form of a U-shaped support-bracket 1, a parallel-parallel pin 2 placed between racks 3 and 4 of the bracket 1 and pivotally connected to its shelf 5, and a cover 6 applied to the common end of the substrate-bracket 1 and pin parallelepiped 2.
Образец изготавливают и испыты- следующим образом.A sample is made and tested as follows.
Между стойками 3 и 4 скобы 1 размещают штифт-параллелепипед 2 и соедин ют их между собой шарниром 7. На одну из общих поверхностей стоек 3 и 4 штифта 2 нанос т одним из известных способов испытуемое покры- :тие 6 шириной А. Закрепл ют полку 5 ;скобы 1 и прикладывают к свободному концу штифта-параллелепипеда 2 наг0Pin-parallelepiped 2 is placed between posts 3 and 4 of bracket 1 and connected to each other by a hinge 7. On one of the common surfaces of racks 3 and 4 of pin 2, the test coating 6 of width A. is fastened with one of the known methods. 5; brackets 1 and applied to the free end of the pin-parallelepiped 2 nag0

рузку Р, под действием которой происходит поворот штифта 2 вокруг шарнира 7 и постепенный отрьш его от испытуемого покрыти 6, При этом о&- разец позвол ет учитывать напр жени от изгиба при повороте штифта 2 относительно скобы 1, возникающие в зоне контакта покрыти 6 со штифтом 2. Измер ют величину отрьшающей нагрузки Р в различных точках ширины А покрыти 6 и по известной формуле определ ют величину адгезии покрыти 6 к основному материалу штифта 2.The control gear P, under the action of which the pin 2 rotates around the hinge 7 and is gradually removed from the test coating 6, and the amp allows to take into account the bending stresses when the pin 2 rotates relative to the bracket 1 arising in the contact zone of the coating 6 with pin 2. Measure the size of the positive load P at various points of width A of the coating 6, and the adhesion value of the coating 6 to the base material of the pin 2 is determined using the known formula.
