Specialists of Kimovsk Radioelectromechanical Plant (KREMP, part of the RosElectronics holding of the Rostec state corporation) have introduced the technology for mechanical processing and application of a complex of galvanic coatings on neodymium magnets, which are used in wind turbine rotors.

Neodymium magnets are good in all aspects, but they have one drawback - low resistance to corrosion. Accordingly, this Russian development will allow to rid the "super magnets" of this disadvantage.

"Neodymium magnets have optimal parameters for use in generator designs. In addition to high power, they lose only about 1% to 2% of their "strength" per year. Whereas classic magnets weaken by 5% to 10% over the same period. However, their biggest disadvantage is extremely low resistance to corrosion. To protect these from the adverse effects of the environment, they are covered with various nickel alloys. Previously in the territory of the Customs Union countries, there were no manufactures capable of carrying out these technological procedures. The launch of new production sites at KREMP will increase technological independence in the production of widely demanded products in the energy sector", - said the general director of AO "KREMP" Vadim Zhollud.
