The　chemical　stability　is　an　important　concern　for　Nd-Fe-B　sintered　magnets　with　respect　to　their　practical　applications.　In　our　present　study,　recycled　Nd-Fe-B　sintered　magnets　with　excellent　magnetic　properties　have　been　fabricated　from　waste　Nd-Fe-B　sintered　magnets　as　well　as　their　corrosion　behavior　were　investigated　and　compared　with　the　original　waste　magnets.　We　find　both　magnets　to　exhibit　approximately　similar　corrosion　processes,　corrosion　rates,　and　magnetic　properties.　Moreover,　potentiodynamic　polarization　curves　and　electrochemical　impedance　spectroscopy　results　reveal　that　both　magnets　exhibit　similar　corrosion　thermodynamics　and　kinetics.　For　comparison,　the　recycled　magnets　have　a　slightly　higher　rare　earth　content　and　more　Nd-rich　grain　boundary　phase　in　their　microstructure　compared　with　those　of　the　original　waste　magnets,　but　with　a　negligible　influence　to　the　corrosion　resistance　of　the　magnets.　We　conclude　that　the　recycling　process　has　no　adverse　influence　on　the　performance　of　these　magnets,　thus　demonstrating　the　applicability　of　the　recycled　Nd-Fe-B　sintered　magnets.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
