Itekhnoloji yokhuseleko lwekhemikhali yeNdfeb Neodymium Magnetubukhulu becala ibandakanya i-electroplating kunye ne-electroless plating yeengubo zentsimbi, ifilimu yokuguqulwa kweengubo ze-ceramic kunye nokutshiza kunye ne-electrophoresis yeengubo eziphilayo.Kwimveliso, ngokuqhelekileyo isetyenziselwa ukulungisa intsimbi yokukhusela intsimbi kumphezulu weemagnethi ze-NdFeb ngenkqubo ye-electroplating.I-Electroplating yinkqubo apho i-workpiece yamagnetic isetyenziswa njenge-cathode kunye ne-cation cation kwisisombululo se-electroplating iyancitshiswa kumphezulu wemagnethi ngokusebenzisa i-current yangaphandle ukwenza i-coating yensimbi.Ukukhuselwa kwe-electroplating yeIimagnethi ze-Sintered Neodymiumubukhulu becala kukuphucula ukumelana nomhlwa kweemagnethi, kunye nokuphucula iipropathi zoomatshini bomphezulu kunye nokuhombisa.
Emva kweminyaka yokuvelisa kunye nokusetyenziswa, iziphene zeNdFeb umazibuthe we-electroplating protective coating nazo zicacile: I-porosity yokwambathisa inkulu, i-coating ayixinene, kwaye inokunyamezela imilo.Ikona ye-workpiece iya kuba ngqiqweni ngenxa yoxinaniso lomgca wamandla kwinkqubo ye-electroplating, ngoko ke ikona yombane.IMazibuthe eZisigxina emhlabenikufuneka chamfered, kwaye isampulu enzulu umngxuma ayikwazi plated.Inkqubo ye-Electroplating inefuthe eliyingozi kwimatriksi yemagnethi.Kwezinye iimeko ezinzima, emva kokuba i-electroplating isetyenziswe ixesha elide, i-coating iya kubonakala iqhekeza, ikhupha, ilula ukuwa kunye nezinye iingxaki, kunye nokusebenza kokukhusela kuya kuncipha.Ngophuculo lokwazisa ngendalo esingqongileyo, umlinganiselo weendleko zizonke zokucoca inkunkuma nge-electroplating ezintathu zonyuka kakhulu.
I-Neodymium Electromagnetiteknoloji ye-nickel plating ibhekisela kwi-REDOX yokusabela kwetyuwa yensimbi kunye ne-agent yokunciphisa kwindawo yokuhlambela ngaphandle kokongezwa kokusetyenziswa kwangoku.Ngaphantsi kwesenzo se-catalytic ye-workpiece surface, inkqubo yokunciphisa i-ion yensimbi.Xa kuthelekiswa ne-electroplating, izixhobo zenkqubo yokucoca i-electroless zilula, ayifuni amandla kunye ne-electrode encedisayo, ubukhulu bokwambathisa bufana, bufaneleke ngakumbi ubume bomsebenzi ontsonkothileyo, iindawo zomngxuma onzulu, umbhobho ongaphakathi wodonga lokwaleka, ukuxinana kunye nobunzima bokwaleka. iphezulu.I-Electroless Plating nayo ineziphene ezithile, ubukhulu bokugquma abunyuki, bunokwaleka iindidi ezininzi, iimfuno zenkqubo ziphezulu kakhulu, ukugcinwa kwebhafu kunzima kakhulu.Ukufakwa kweekhemikhali kukwenza i-nickel plating, i-copper plating kunye nesilivere.
Ukongeza, inkqubo yeIimagnethi ze-Sintered Neodymiumzityekele kwimingxunya encinci, isakhiwo esixekethileyo, umphezulu orhabaxa kunye nezinye iziphene, kunye nemagnethi esisigxina yeNdFeb kwisicelo sendawo yokusebenza idla ngokuba nobushushu obuphezulu, ukufuma okuphezulu.Ezi ziphene zibonelela ngeemeko ezifanelekileyo ze-NdFeb umazibuthe umhlwa kwiqondo lobushushu eliphezulu kunye nokufuma okuphezulu kokusingqongileyo.Ngexesha elifanayo, inkqubo yokuvelisa i-NdFeB kulula ukuquka i-O, H, Cl kunye nezinye izinto ezingcolileyo kunye neekhompawundi zazo, umphumo onobungozi yi-O kunye neCl element, imagnethi kunye ne-Oxidation corrosion, kunye neCl kunye neekhompawundi zayo ziya kukhawulezisa i-oxidation. inkqubo umazibuthe.Izizathu zokubola lula kweemagnethi zeNdFeb zibangelwa ikakhulu: indawo yokusebenza, ulwakhiwo lwemathiriyeli kunye nobugcisa bemveliso.Uphando lubonisa ukuba ukuthotywa kwemagnethi ye-NdFeB kwenzeka ikakhulu kwezi ndawo zintathu zilandelayo: indawo efudumeleyo nefumileyo, imekobume ye-electrochemical, ixesha elide ubushushu obuphezulu kwindawo eyomileyo, xa ubushushu bungaphantsi kwe-150 ℃, izinga le-oxidation ye-NdFeb umazibuthe liphezulu kakhulu. kade.
