Abstract
The paper gives results of investigation of structure and properties of metal deposited by the induction surfacing method that involves screening of thermal and electromagnetic fields. It is shown that owing to screening the non-uniformity of thickness of the deposited metal layer is decreased by 12%, saving of power amounts to 10-15%, overheating of the edge of disc and deposited metal is eliminated, and the time of surfacing is reduced as compared with surfacing without screening. In this case the microstructure, hardness and wear resistance of the deposited metal remain at the same level as in induction surfacing without screening
Keywords: induction surfacing, inductor, specific power, thermal and electromagnetic screening, deposited metal, carbides, microhardness, structure, wear resistance
