Yuav ua li cas Magnet Coatings cuam tshuam rau kev ua tau zoo ntawm U Shaped Neodymium Magnets

U-shaped neodymium hlau nplaum muab cov hlau nplaum sib nqus zoo tshaj plaws, tab sis lawv kuj ntsib qhov tsis zoo vim lawv cov duab geometry thiab cov khoom siv los ntawm cov khoom siv neodymium. Thaum cov tub ntxhais hlau alloy tsim lub zog sib nqus, lub txheej yog nws cov txheej txheem tiv thaiv tseem ceeb, uas ncaj qha txiav txim siab nws qhov kev ua tau zoo, kev nyab xeeb thiab kev pabcuam lub neej. Kev saib xyuas cov txheej txheej xaiv tuaj yeem ua rau ua tsis tiav ntxov, txo lub zog lossis puas tsuaj puas tsuaj.

Lub luag haujlwm tseem ceeb ntawm Cov Txheej Txheem
Cov hlau nplaum neodymium corrode sai heev thaum raug cov av noo, av noo, ntsev lossis tshuaj lom neeg, ua rau cov hlau nplaum sib nqus tsis tuaj yeem tawg thiab cov txheej txheem brittleness. Cov duab U-shaped exacerbates cov kev pheej hmoo no: nws cov ntse sab hauv khoov concentrates mechanical stress, nws constrained geometry traps contaminants, thiab nws txoj kev nkhaus sib tw txheej uniformity. Tsis muaj kev tiv thaiv muaj zog, corrosion tuaj yeem pib ntawm qhov khoov sab hauv, eroding magnetic output thiab pib tawg uas tuaj yeem ua rau cov hlau nplaum tawg.

Coatings ua ntau tshaj li kev tiv thaiv corrosion
Cov txheej txheem zoo ua raws li ntau yam kev tiv thaiv: lawv tsim lub cev thaiv kev tiv thaiv ib puag ncig, txhim khu kev tiv thaiv khawb thiab chipping thaum tuav, muab hluav taws xob rwb thaiv tsev rau lub cev muaj zog / sensor, thiab tswj cov adhesion hauv thermal stress. Kev sib sib zog nqus ntawm kaum sab xis yog qhov tseem ceeb rau U-zoo li cov hlau nplaum-txhua qhov khoob yuav ua rau kev ua haujlwm tsis zoo nyob rau hauv qhov chaw muaj kev ntxhov siab.

Kev sib piv ntawm Cov Txheej Txheem Txheej Txheem
Nickel-Copper-Nickel (Ni-Cu-Ni) plating tsis tshua kim thiab muab kev tiv thaiv zoo tag nrho thiab hnav tsis kam, tab sis muaj kev pheej hmoo ntawm micro-porosity thiab tsis sib xws hauv U-khoov, yog li nws yog qhov zoo tshaj plaws rau kev siv sab hauv tsev qhuav.
Epoxy coatings ua tau zoo nyob rau hauv ib puag ncig hnyav - lawv cov txheej tuab, cov kua dej ntau nkag mus tob rau hauv qhov khoov, muab cov dej noo / tshuaj tiv thaiv zoo thiab hluav taws xob rwb thaiv tsev, tab sis lawv txi qee qhov khawb.
Parylene muab flawless, pinhole-dawb molecular encapsulation txawm nyob rau hauv qhov sib sib zog nqus khoob, ua rau nws zoo tagnrho rau cov huab cua txias (kev kho mob, aerospace), tab sis nws cov neeg kho tshuab kev tiv thaiv yog txwv thiab nws cov nqi yog siab.
Zinc tuaj yeem siv los ua ib qho kev txi rau hauv ib puag ncig me me uas nws muaj kev lag luam, tab sis tsis muaj lub sij hawm ntev.
Kub ua kom muaj kev tiv thaiv corrosion thiab conductivity hauv cov khoom siv hluav taws xob tshwj xeeb, tab sis yuav tsum tau siv nrog cov npib tsib xee rau kev txhawb nqa.

Cov nyhuv ntawm txheej xaiv ntawm kev ua tau zoo
Coatings ncaj qha txiav txim siab sib nqus ruaj khov-corrosion tas li txo Gauss lub zog thiab rub lub zog. Nws tswj cov txheej txheem kev ncaj ncees los ntawm kev tiv thaiv cov kab nrib pleb hauv uncoated puab khoov. Nws ua kom muaj kev nyab xeeb los ntawm inhibiting kev ntxhov siab tawg tawg. Los ntawm kev xav txog hluav taws xob, txheej txheej tiv thaiv luv luv Circuit Court (epoxy / parylene) lossis ua kom cov dej ntws tam sim no (nickel / kub). Qhov tseem ceeb, cov txheej txheem tsis sib haum tsis ua haujlwm nyob rau hauv ib puag ncig hnyav: tus qauv nickel-plated U-zoo li cov hlau nplaum corrode sai hauv qhov chaw ntub dej, thaum cov hlau nplaum tsis muaj hlau nplaum tuaj yeem cuam tshuam nrog cov khoom siv hluav taws xob nyob ze.

Xaiv cov txheej zoo tshaj plaws: Cov ntsiab lus tseem ceeb
Ua ntej koj qhov chaw ua haujlwm ua ntej: ntsuas cov av noo, qhov kub thiab txias hloov pauv, raug tshuaj lom neeg, thiab siv sab hauv tsev / sab nraum zoov. Txiav txim siab lub neej kev pab cuam - hnyav hu rau epoxy lossis parylene txheej. Txheeb xyuas cov kev xav tau hluav taws xob: rwb thaiv tsev hu rau epoxy/parylene coatings; conductivity hu rau nickel / kub txheej. Ntsuam xyuas kev ua haujlwm ntawm cov khoom siv: cov nickel coatings yog cov resistant rau hnav dua li softer epoxy coatings. Ib txwm hais txog kev khoov sab hauv - cov neeg muag khoom yuav tsum lav qhov sib xws hauv cheeb tsam no los ntawm cov txheej txheem tshwj xeeb. Cov nqi sib npaug thiab kev pheej hmoo: Kev ntsuas kev tiv thaiv tsis txaus tuaj yeem ua rau raug nqi tsis zoo. Rau cov ntawv thov tseem ceeb, tswj xyuas cov tshuaj ntsev ntsev

Siv cov kev coj ua zoo tshaj plaws
Qhia meej meej lub xeev txheej hom thiab qhov tsawg kawg nkaus tuab hauv cov lus qhia tshwj xeeb (piv txwv li, "30μm epoxy"). Xav kom cov tuam txhab muab cov ntaub ntawv pov thawj ntawm inbend kev pab them nqi. Ua hauj lwm nrog cov kws txawj paub txog U-zoo li tus hlau nplaum geometries - lawv txheej txheej txheem yog calibrated rau complex duab. Kuaj prototypes nyob rau hauv lub ntiaj teb no tiag tiag tej yam kev mob ua ntej tag nrho cov ntau lawm; Tshem tawm lawv mus rau qhov kub thiab txias, tshuaj lom neeg, lossis av noo los xyuas qhov ua tau zoo.

Xaus: Txheej raws li tus neeg saib xyuas zoo
Rau U-shaped neodymium hlau nplaum, txheej txheej tsis yog kev kho deg, tab sis tseem ceeb tiv thaiv kev ntseeg tau. Xaiv epoxy coatings rau qhov chaw ntub dej, parylene txheej rau kev phais kom raug, lossis cov txheej txheem txheej txheem plating rau kev ua tau zoo tuaj yeem hloov pauv mus rau qhov nyuaj. Los ntawm kev sib piv cov txheej txheem kev ua tau zoo rau daim ntawv thov kev xav tau thiab tshawb xyuas kev tiv thaiv ntawm qhov tseem ceeb inbends, koj tuaj yeem ua kom cov hlau nplaum ua tau zoo rau ntau xyoo. Tsis txhob cuam tshuam rau kev tiv thaiv txheej: koj lub zog hlau nplaum nyob ntawm nws.
