Churnosov A. Magnetic non-destructive quality control method of vibrouprochnyaemogo layer of metal

An object is control of quality of vibrostrengthening of superficial layer of metal. A research purpose is creation of method and device for control of the fixed layer on the surface of steelworks on the basis of combination a magnetic gradient and electromagnetic multifrequency methods of control which gives possibility to create a device express - control of quality of the vibrostrengthened layer of metal. Research methods - method of calculation of magnetic-field in a ferromagnetic nonlinear environment by the numeral decision of vector integral equation, method of theorem about reciprocity, method of harmonic analysis, methods of model experiment. The theoretical and practical results of -теоретично are reasonable principle of construction of measuring transformer, the method of gradient of magnetic-field and multifrequency electromagnetic method which gives possibility with the help of linear combinations of initial signals to determine a microhardness and thickness of the vibrostrengthened layer is united in which, the construction of device is worked out for control of hardness and thickness of vibrostrengthening of superficial layer of metal. Novelty - a task to control of hardness and thickness of the vibrofixed layer of ferromagnetic wares is first decided. For control of the vibrostrengthened layer the combined method in which the method of measuring of gradient of the field of dispersion of the local magnetized area of detail and method of the twofrequency magnetizing is united by the sinewave magnetic field is offered. Degree of introduction - a robot is inculcated on LTD. "Інтерсевіс" (Ukraine), and in the laboratory of "Electrodynamics" of the Східноукраїнського national university of the name of Volodymyr Даля (Ukraine). Industry of the use is an instrument-making.
