Abstract

In the current trends towards saving and increasing the efficiency of electricity use, magnetic materials of the Nd–Fe–B system are widely used in the production of fully electric vehicles: cars (Tesla), aircraft, as well as new energy sources – for example, wind turbines. Considers various methods of applying protective coatings to magnetic materials of the Nd–Fe–B system, surface preparation modes and evaluates the effect of the technology of applying anticorrosive coatings on their protective ability, the magnitude of residual induction and coercive force on the magnetization of magnetic materials.
