COATING INTEGRITY DETERMINATION METHOD AT ITS DEFORMATION Russian patent published in 2017 - IPC G01N27/27 G01N15/08 

FIELD: measuring equipment.

SUBSTANCE: method includes the connection operation to the meter of electrolytic cell and the sample with testing coat and the contact creating operation of the testing coat with the electrically conducting liquid, pre-filled in the electrolytic cell. The method according to the invention is added with the operation of current source connecting to the electrical circuit, formed by the metal sample with the testing coat, the electrolytic cell and the measuring device, and the operation at which simultaneously perform the continuous deformation of the metal sample with the testing coat and the continuous monitoring of the testing coat continuity applied on it.

EFFECT: possibility of the dielectric coats continuity operational research and the dielectric coats strength operational determination with high accuracy in the process of continuous deformation of metal samples with the dielectric coats, for example, when drawing in the metal sample with cavity coated according to Erikson.
