THE REVIEW OF PATENTS FOR INVENTIONS, UTILITY MODELS, INDUSTRIAL MODELS

The new technical solutions including inventions in the area of nanotechnology and nanomaterials are efficiently applied in communal and housing services as well as in construction and other joint fields. The invention ?The diagnostics method for defects on the metal surfaces (RU 2581441)? refers to the methods used to detect defects and cracks on the surface of metal equipment and pipe lines. The suspension of metal nanoparticles is consistently applied on the surface of controlled object following direction from the bigger diameter to the smaller one. The nanoparticles possess the photoluminescence property and their shape is spheric with different diameters. After each application the surface is dried and excessive particles are removed. Then rowwise scanning of object surface is executed with the ray of femtosecond laser and at the same time the intensity of the two-photon luminescence signal is registered in every studied area fixing the location of this area and obtaining the map of glow intensity distribution of nanoparticles exited by the laser radiation. The maps shows the zones with the maximal glow intensity, the coor dinates and shape of the determined glow zone make it possible to determine the coordinates and shape of the defect and the size of its intersection is considered to be equal to relative diameter of the applied nanoparticles at this application stage. The technical stage is increased reliability and credibility of the study.
