Abstract
Considered are existing technological schemes of induction surfacing of operating elements of agriculture machines. The best results are provided by continuous induction surfacing using double-loop circular inductor, heat and electromagnetic shields, horizontal vibration and rotation of part being surfaced. Application of developed technological schemes and equipment for induction surfacing of thin disks allows increasing productivity, saving electric energy, improving microstructure, increasing wear resistance and stability of thickness of deposited layer as well as reducing residual stresses and deformations of disks. 16 Ref., 6 Figures.
