Specialists from Kimovsk Radioelectromechanical Plant (KREMP, part of "Roselectronica" holding of "Rostec" state corporation) have implemented a technology for machining and applying a complex of electroplated coatings to neodymium magnets used in wind generator rotors.
Neodymium magnets are good in every way, but they have one drawback – low corrosion resistance. Accordingly, the Russian development will eliminate this disadvantage of "supermagnets".
«Neodymium magnets have optimal parameters for use in generator design. In addition to high power, they lose only 1% to 2% of their "strength" per year. While classic magnets weaken by 5% to 10% over the same time. However, their major disadvantage is extremely low corrosion resistance. To protect them from adverse environmental influences, they are coated with various nickel alloys. Previously, there were no production facilities in the countries of the Customs Union capable of performing these technological processes. The launch of new production sites at KREMP will increase technological independence in the manufacture of products widely demanded in the energy sector», – said Vadim Zholud, General Director of JSC "KREMP".
