Specialists from Kimovsk Radioelectromechanical Plant (KREMP, part of the "Ruselectronics" holding of the Rostec State Corporation) have implemented a technology for machining and applying a complex of galvanic coatings to neodymium magnets used in wind turbine 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 designs. In addition to high power, they lose only 1% to 2% of their "strength" per year. In contrast, classic magnets weaken by 5% to 10% over the same period. 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 Customs Union countries capable of performing these technological processes. The launch of new production sites at KREMP will increase technological independence in the manufacturing of products widely demanded in the energy sector», – said Vadim Zholud, General Director of JSC "KREMP".
