Projekti eesmärgiks on NdFeB magnetite alase kompetentsi arendamine. Arendatakse odavamaid ja väiksema keskonnamõjuga magnetmaterjale, mille omadused oleksid paremad või vähemalt samal tasemel hetkel saadavalolevate materjalidega ning valikukriteeriume erinevatesse rakendustesse sobivate magnetmaterjalide valikuks.
Tegevused (alateemad):
- Stabiilse mikrostruktuuri ja koostisega magnetsulamite valmistamine induktsioonsulatuse ja ribavalumeetodi abil;
- Parendatud omadustega magnetite arendamine kõrgetemperatuursetesse rakendustesse (kuni 150 °C ) ja mõõdukalt korrosiivsetesse keskkondadesse;
- Nd ja Dy asendamine odavamate alternatiividega;
- Uute magnetmaterjalide disain tuulegeneraatoritesse.
The general goal of the project is to gain deeper insights into the magnetic properties of NdFeB magnets and develop criteria’s for the selection of suitable alloy compositions and microstructures; to design materials with comparable or even better magnetic properties to materials commercially available today but with reduced cost and impact on the environment.Topics:
- Development PM alloys with controlled composition and microstructure based on NdFeB induction melting and melt-spinning;
- Development magnets with improved performance at high operation temperatures (up to 150 °C) and/or combined mildly corrosive environments;
- Protyping of several new grades of permanent magnets with reduced content of Nd and Dy providing alternatives to those of manufactured by conventional compositions and methods;
- Design of new materials and grades for wind generators.
