摘要：

The　waste　sintered　Nd-Fe-B　magnets　were　recycled　to　fabricate　anisotropic　bonded　magnets　by　the　combination　of　hydrogen　decrepitation　(HD)　and　NdHx　nanoparticle　modification.　Magnetic　properties　of　the　recycled　magnetic　powders　and　bonded　magnets　were　investigated.　Adding　NdHx　nanoparticles　to　HD　powders　may　increase　the　coercivity　of　the　recycled　powders.　The　HD　powders　with　10　wt.　%　NdHx　degassed　at　973　K　for　5　h　bear　magnetic　properties　of　B-r　of　9.36　kGs　and　H-ci　of　12.36　kOe.　The　recycled　bonded　magnet　exhibits　good　magnetic　properties　of　B-r　=　7.61　kGs,　H-ci　=　12.93　kOe,　and　(BH)(max)　=　11.56　MGOe.
