Description
The corrosion behaviour of uncoated bonded Nd-Fe-B magnets prepared using different binders has been assessed in a humid environment (100 C, saturated water vapour) by means of mass change measurements and magnetic characterisation. Epoxy resin, zinc and polytetrafluoroethylene (PTFE) have been used to bond melt spun ribbon, MQP-D, as supplied by General Motors. It has been found that the PTFE bonded samples which had been heat treated prior to testing exhibit superior corrosion resistance to the other samples, as characterised by a smaller mass change and greater retention of magnetic properties.
