Technical and economic indices: Technology of micro-plasma-spark alloying with ultrasound modification (MPSA + USM) serves to restore and strengthen any current conducting surfaces of optional shape and sizes. This method ensures the following advantages: - Possibility to use compound components electrodes or synthesized composite materials as alloying electrodes, ensuring polyfunctional coatings on working surfaces; - 100 % adhesion of the coating with a substrate; - Lowering stress gradient in the sprayed coating; - Low roughness of the strengthened working surfaces; - Preserving a profile and product geometry in the treatment process; - Absence of necessity for mechanical finishing the product after strengthening; - Increase of a period of exploitation without repair, decrease of regrinding quantity; - Possibility of restoration and strengthening of precision products of plunger pair type, that is difficult to fulfill by any other way; - Considerably lower power intensity and the coating cost as compared with the gas-flame and ion-plasma methods, laser processing. Structure of the strengthened area: Strengthened area with the nanostructural structures in the surface layer of the product is saturated with double and triple carbide systems in a spherical form, alloying of surface layer of the substrate on the depth up to 200 μm. Field of the technology application: Machinery, aircraft building, metal and wood treatment, production of consumer goods. Novelty: The patent is in force in CIS countries.
