The purpose of this theoretical investigation is the modeling of finish-strengthening under conditions of a rotating field for the definition of ferromagnetic indenter kinematic properties. This method is based on functioning devices offered by D.D. Logvinenko. The basis of these devices is an inductor located into the case. This inductor represents a modified stator of an induction motor. In the stator bore there is installed a cylindrical pipe made of nonmagnetic material the inner surface of which limits a working area of the device. From the obtained results of theoretical researches it follows that the kinematic properties of ferromagnetic indenters are defined by field parameters – induction of a direct and an alternating fields, frequency and gradient of induction of an alternating field, and also magnetic and inertial properties of indenters.

The main technological stages that ensure the pro-cessing of sludge waste from grinding production are considered and their essence is disclosed. De-sign and technological solutions are proposed that ensure their implementation using an electromag-netic field. The main conclusions are presented, showing the feasibility of using these devices.

The paper reports the analysis of a problem current state connected with manufacturing high-quality composite powders. There is offered a device which allows obtaining a high uniformity of alloy addition distribution under conditions of a magnetic vibrating layer, and also metal polymeric composite powders. A designed model allowing the definition of a gradient interval of magnetic field induction is obtained, at which powder cluster destruction takes place and powder stable magnetic boiling is supported.
