DEVICE FOR FORMING AND TESTING OF SAMPLES OF THIN COATINGS Russian patent published in 2015 - IPC G01N1/28 G01N3/18 

FIELD: test equipment.

SUBSTANCE: invention relates to laboratory test equipment, namely to the device for forming and testing of samples of thin coatings in loading devices, for example, for testing of thin ceramic heat-shielding coatings for tensile strength. The device is a two-piece unit intended for placement in the load device comprising two cylindrical and circular details the external surface of which is intended for application, at least, of one layer of thin coating and forming of a sample. One of cylindrical details has on the axis a cylindrical cavity, and another one a companion cylindrical ledge placed through a ring hole in a cavity and connecting the details. The external surface of cylindrical details has adhesion, and a ring surface has applied coatings without adhesion, and serve, respectively, for forming of a sample as a connecting layer and/or non- adhesion thin coating.

EFFECT: improvement of reliability of study of strength properties of thin coatings by forming of non-adhesion longitudinal superficial sample on the two-piece unit suitable for loading by longitudinal and temperature loads.
