摘要

Aims: The purpose of this work is to study the effect of compression pressure on isotropic epoxy resin bonded Nd-Fe-B magnets, with the goal of achieving high densities at room temperature. Methodology: We present data on the effect of the applied pressure on the structure and magnetic properties of a series of polymer bonded magnets based on MQ-powders with a distribution of grain sizes and coated with various thickness of epoxy resins. Results: Densities of the order 83% of the theoretical estimated density value were achieved with an energy product of 10.33 MGOe. By increasing the molding pressure the density and the energy product of the bonded magnets was increased. Conclusion: The combination of high density with good energy product is desirable for numerous applications especially within the automotive sector.
