Abstract
Изобретение относитс к испытательной технике, а именно к получению и подготовке образцов дл исследовани , и может быть использовано дл определени трещиноустойчивости противопригарных покрытий дл литейных форм и стержней. Целью изобретени вл етс повышение информативности о трещиностойкости покрыти за счет увеличени разнообрази конфигураций поверхности образца. Образец выполнен в виде цилиндра 1 с центральным отверстием 2. К цилиндру 1 с внешней стороны примыкает пр моугольна призма 3 с полусферой 4 на свободном конце. Призма 3 сопр гаетс с цилиндром 1 по радиусу 5. На торцовой поверхности цилиндра 1 со стороны большего диаметра отверсти 2 выполнена кольцева проточка 6. Благодар наличию разнообразных форм поверхностей и их сопр жений испытуемое покрытие подвергаетс действию различного рода напр жений, что позвол ет получить более полную картину о свойствах покрыти . 3 ил.The invention relates to a testing technique, namely to the preparation and preparation of samples for testing, and can be used to determine the crack resistance of anti-stick coatings for molds and cores. The aim of the invention is to increase the information content of the crack resistance of the coating by increasing the variety of the sample surface configurations. The sample is made in the form of a cylinder 1 with a central hole 2. A rectangular prism 3 with a hemisphere 4 at the free end is adjacent to the cylinder 1 from the outside. The prism 3 mates with cylinder 1 along radius 5. On the end surface of cylinder 1, a circular groove 6 is made on the side of the larger diameter of the hole 2. complete picture of coating properties. 3 il.
