We　have　produced　an　anisotropic　N15.5Dy1.0　Fe72.7Co3.0B6.8Al1.0　magnet　by　the　spark　plasma　sintering　(SPS)　technique　and　compared　it　with　a　magnet　of　the　same　composition　processed　by　the　conventional　sintering　method.　We　investigated　magnetic　properties,　microstructure,　and　constituents　by　a　B-H　loop-line　instrument,　a　scanning　electron　microscope,　and　an　energy-dispersive　X-ray　detector,　and　studied　the　effects　of　processing　conditions　on　the　magnetic　properties,　dimensional　precision,　and　density.　We　also　examined　the　magnet＇s　electro-chemical　properties　in　electrolytes　and　its　corrosion　behavior　in　oxidizing　environments.　We　found　that　the　microstructure　of　the　SPS　NdFeB　magnet　is　different　from　that　of　the　conventional　one.　In　the　SPS-processed　magnet,　the　grain　size　is　fine　and　uniform.　while　the　distribution　of　the　Nd-rich　phase　is　heterogeneous.　The　SPS　NdFeB　magnet　has　a　maximum　energy　product　of　240　kJ/m(3)　and　a　coercive　force　of　1260　kA/m.　The　density　of　the　magnet　reaches　7.58　g/cm(3),　and　its　dimensional　precision　is　about　20　mum.　The　electrochemical　properties　and　the　corrosion　resistance　of　the　SPS　NdFeB　magnet　are　better　than　those　of　the　conventional　one.　The　SPS　process　is　a　promising　method　for　the　production　of　NdFeB　magnets　with　ideal　overall　performance.
