Imifuniselo ye-Xinfeng yabonisa ukuba i-cubic centimeter yeSintered NdFeb Magnetizakungcoliswa yi-oxidation emva kokuvezwa emoyeni kwi-150 ℃ kangangeentsuku ezingama-51.I-corrodes ngokulula kwizisombululo ze-asidi ezibuthathaka.Ukuze wenze i-NdFeb Permanent Magnet ikwazi ukuhlala ixesha elide, kufuneka ibe neminyaka engama-20 ukuya kwengama-30 yobomi benkonzo, kufuneka ingene kunyango lwe-corrosion engaphezulu, ukuze ikwazi ukumelana nokudleka kwezinto ezityiwayo kwi-Magnet.Kwaye ngokuqhelekileyo kuthiwaElectroplating Permanent Magnet.
Okwangoku, i-Sintered NdFeb esisigxina yenkqubo yemagnethi yokuvelisa imveliso ithatha isinyithi sombane, i-electroplating + ikhemikhali yegolide, i-electrophoretic coating kunye nonyango lwe-phosphating, njl. i-corrosive medium yahlulwe, ukwenzela ukuthintela umonakalo ophakathi kwimagnethi.
1.Ngokubanzi igalvanized, nickel + copper + nickel, nickel + copper + electroless nickel plating iinkqubo ezintathu, ezinye iimfuno zentsimbi, ngokubanzi kwi-nickel plating kunye nezinye i-metal plating.
2.Kwezinye iimeko ezizodwa ziya kusebenzisa i-phosphating
1) Kwiimveliso zemagnethi zeNdFeb ngenxa yenguquko, ixesha lokugcinwa lide kakhulu kwaye lingacacanga indlela yonyango lomphezulu, ukusebenzisa i-phosphating kulula kwaye kulula;2Inkqubo ye-Phosphating inokuphucula amandla okungena kwindawo yamagnetic.
I-3.I-Electrophoretic coating ibe yenye yezona zinto zisetyenziswa kakhulu kwi-anti-corrosion surface treatment techniques.Ngenxa yokuba ayinawo amandla okudibanisa kunye nomphezulu wemagnethi evuzayo, kodwa inokumelana nokugqwala kwesitshizi setyuwa, iasidi kunye nealkali, njl., ukumelana nokugqwesa kokugqwesa.Kodwa xa kuthelekiswa nengubo yokutshiza, ukumelana kwayo nobushushu kunye nokufuma kukwimeko embi.
Abathengi banokukhetha ukutyabeka ngokweemfuno zabo zomsebenzi wemveliso.Ngokwandiswa kwezicelo zeemoto, abathengi baneemfuno eziphezulu zokuxhathisa umhlwa kwe-NdFeb, kunyeUmgangatho ophezulu we-Electroplating Permanent Magnetiyafuneka.Umfuniselo we-HAST (umfuniselo we-PCT) uyilelwe ukuvavanya ukuxhathisa kokutya kwemagnethi esisigxina ye-NdFeb kwindawo emanzi kunye nobushushu obuphezulu.
Abathengi babona njani ukuba i-coating iyahlangabezana neemfuno?Umfuniselo wokutshiza ityuwa yinjongo yomphezulu we-anti-corrosion coating ephathwa nge-sintered NdFeb umazibuthe ukwenza umfuniselo okhawulezayo wokuchasana nomhlwa, ekupheleni kovavanyo, isampuli evela kwibhokisi yovavanyo, yomile, ngamehlo okanye iglasi yokukhulisa jonga umphezulu wesampulu enamabala, amabala obungakanani bokutshintsha kombala webhokisi.
Ukushwankathela, kuphela ngokuqonda inkqubo yokuvelisa kunye neemfuno zemveliso umthengi unokugweba ngokuchanekileyo ukuhambelana kwemveliso.Ngamafutshane, kukubamba ukusebenza, ukulawula ukunyamezela kwe-dimensional, ukuchongwa kwengubo kunye novavanyo lwenkangeleko.
Ngokwemigaqo yokusebenza, i-Br (i-magnetism eseleyo), i-Hcb (ukunyanzeliswa), i-Hcj (i-intrinsic coercivity), (BH) Max (ubuninzi bemveliso yamandla kazibuthe) kunye ne-demagnetization curve inokubonwa ngokusebenza.Ukunyamezela kwe-Dimensional, ukuchaneka kunokulinganiswa nge-vernier calipers;Kwi-coating, umbala kunye nokukhanya kwengubo kunokubonwa ngeso lenyama kwaye ifunyenwe ngokubopha amandla kunye novavanyo lokutshiza ityuwa.Imbonakalo iyonke, ngakumbi ngeliso leze okanye iglasi yokukhulisa, okanye imicroscope yamehlo (kwimveliso yomgca ongaphantsi kwe-0.2mm), umphezulu wemagnethi ugudile, akukho masuntswana abonakalayo kunye nemizimba yangaphandle, akukho mabala, akukho edge ewayo ewayo, imbonakalo ifanelekile.
