METHOD OF MONITORING AND DIAGNOSTICS OF RESISTANCE OF COATING TO ACTION OF EXTERNAL LOADS Russian patent published in 2016 - IPC G01N3/60 G01N19/04 

FIELD: test equipment.

SUBSTANCE: invention relates to the field of control and diagnostics aggregate performance properties of wear-resistant coatings, related primarily to the hardness, adhesion strength, wear resistance, and can be used in mechanical engineering, shipbuilding and other fields, as well as coatings which are under cyclic loading involving primarily with erosion resistance surface. Essence: impact of the indenter is performed on the sample with wear-resistant coatings distorting load to failure of the coating and evaluate the effects. Exposure is carried out using a high-speed jet liquid used as an indenter, at 300…1000 m / s for the samples previously passed cyclic loading having wave non-stationary character, and evaluate the effects on the jet velocity, at which the intensive degradation of the coating or the feed rate of the nozzle head relative to the surface of the diagnosed sample or article in which the intensive destruction coating or hydrocavern length from the start of exposure to the point of complete fracture of the coating or the depth and width hydrocavern.

EFFECT: enhanced monitoring and diagnosis of the stability of the coating to the action of external loads to determine the residual life of the coatings on the samples.
