Xinfeng qhov kev sim tau pom tias qhov cubic centimeter ntawmSintered NdFeb Magnetyuav corroded los ntawm oxidation tom qab raug rau huab cua ntawm 150 ℃ rau 51 hnub.Nws corrodes yooj yim dua nyob rau hauv tsis muaj zog acid daws.Txhawm rau ua kom NdFeb Permanent Magnet ruaj khov, nws yuav tsum muaj 20-30 xyoo ntawm kev pabcuam lub neej, nws yuav tsum tau txais kev kho deg corrosion, thiaj li tiv thaiv corrosion ntawm corrosive nruab nrab ntawm Magnet.Thiab feem ntau nws yog hu uaElectroplating Permanent Magnet.
Tam sim no, sintered NdFeb ruaj khov hlau nplaum tsim kev lag luam feem ntau siv electroplating hlau, electroplating + tshuaj kub-plating, electrophoretic txheej thiab phosphating kev kho mob, thiab lwm yam., nyob rau saum npoo ntawm cov hlau nplaum yog coated nrog ib txheej ntxiv ntawm kev rho tawm, cov hlau nplaum nto thiab corrosive nruab nrab yog sib cais, txhawm rau tiv thaiv kev puas tsuaj ntawm qhov nruab nrab rau cov hlau nplaum.
1.Generally galvanized, npib tsib xee + tooj liab + npib tsib xee, npib tsib xee + tooj liab + electroless npib tsib xee plating peb txheej txheem, lwm yam hlau plating yuav tsum, feem ntau nyob rau hauv nickel plating thiab ces lwm yam hlau plating.
2.Nyob rau qee qhov tshwj xeeb tseem yuav siv phosphating
1) Hauv NdFeb cov khoom lag luam hlau nplaum vim kev hloov pauv, lub sijhawm khaws cia ntev dhau lawm thiab tsis paub meej txog kev kho qhov chaw, siv phosphating yog qhov yooj yim thiab yooj yim;(2) Thaum cov hlau nplaum xav tau epoxy nplaum, xim, kua nplaum, xim thiab lwm yam epoxy organic bonding quab yuam yuav tsum muaj cov substrate kom muaj kev ua haujlwm zoo.Cov txheej txheem phosphating tuaj yeem txhim kho lub peev xwm infiltration ntawm magnetic nto.
3.Electrophoretic txheej tau dhau los ua ib qho ntawm feem ntau siv los tiv thaiv corrosion nto txheej txheem.Vim tias nws tsis tsuas yog muaj kev sib raug zoo nrog lub ntsej muag ntawm cov hlau nplaum, tab sis kuj muaj corrosion kuj ntawm ntsev tsuag, kua qaub thiab alkali, thiab lwm yam, zoo heev corrosion kuj.Tab sis piv nrog cov tshuaj tsuag txheej, nws tsis kam mus rau tshav kub thiab av noo tsis zoo.
Cov neeg siv khoom tuaj yeem xaiv cov txheej txheem raws li lawv cov khoom ua haujlwm.Nrog rau kev nthuav dav ntawm daim ntawv thov lub cev muaj zog, cov neeg siv khoom muaj kev xav tau ntau dua rau NdFeb corrosion kuj, thiabHigh Quality Electroplating Permanent Magnetyog xav tau.Kev sim HAST (PCT xyaum ua) yog tsim los ntsuas qhov kev tiv thaiv corrosion ntawm sintered NdFeb cov hlau nplaum ruaj khov hauv qhov chaw ntub dej thiab kub kub.
Yuav ua li cas cov neeg siv khoom txiav txim siab seb lub txheej puas ua tau raws li qhov yuav tsum tau ua?Kev sim tshuaj ntsev ntsev yog lub hom phiaj ntawm qhov saum npoo ntawm cov txheej txheem tiv thaiv corrosion kho sintered NdFeb hlau nplaum los ua qhov kev sim ceev los tiv thaiv corrosion, thaum kawg ntawm qhov kev sim, cov qauv los ntawm lub thawv kuaj, qhuav, nrog ob lub qhov muag lossis iav tsom rau. soj ntsuam cov qauv saum npoo nrog cov me ntsis, me ntsis ntawm qhov loj ntawm lub thawv xim hloov.
Txhawm rau ua kom tiav, tsuas yog los ntawm kev nkag siab txog cov txheej txheem tsim khoom thiab cov kev xav tau ntawm cov khoom tuaj yeem ua tus neeg siv khoom txiav txim kom raug raws li cov khoom lag luam.Nyob rau hauv ib tug nutshell, nws yog tus tuav ntawm kev ua tau zoo, kev tswj ntawm qhov ntev kam rau ua, nrhiav kom tau cov txheej thiab kev ntsuam xyuas ntawm cov tsos.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, Br (cov hlau nplaum seem), Hcb (coercivity), Hcj (intrinsic coercivity), (BH) Max (cov khoom siv hluav taws xob ntau tshaj plaws) thiab demagnetization nkhaus tuaj yeem kuaj pom los ntawm kev ua haujlwm.Dimensional kam rau ua, qhov tseeb tuaj yeem ntsuas los ntawm vernier calipers;Ntawm txheej txheej, xim thiab ci ci ntawm txheej tuaj yeem pom los ntawm qhov muag liab qab thiab kuaj pom los ntawm kev sib khi quab yuam thiab ntsev tsuag tshuaj ntsuam.Zuag qhia tag nrho cov tsos, feem ntau yog nrog lub qhov muag liab qab los yog iav magnifying, los yog optical microscope (rau cov khoom kab tsawg tshaj li 0.2 hli), qhov saum npoo ntawm cov hlau nplaum yog du, tsis pom cov khoom thiab txawv teb chaws lub cev, tsis muaj pob, tsis muaj ntug ntog, qhov tsos yog tsim nyog.
