Cov ntaub ntawv hlau nplaum tas mus li muaj cov ntsiab lus hlau, hlau qhia qhov tseem ceeb tshaj plaws ferromagnetic zog ntawm txhua lub ntsiab lus, uas yog vim li cas nws muaj nyob rau hauv cov hlau nplaum muaj zog tshaj plaws. Txawm li cas los xij, hlau yog qhov muaj zog heev rau dej, ua cov hlau nplaum nrog cov ntsiab lus hlau siab heev rau corrosion.
Lwm cov ntsiab lus ferromagnetic siv nyob rau hauv ntau hom hlau nplaum tas mus li muaj xws li npib tsib xee, cobalt, gadolinium, thiab dysprosium, tag nrho cov no muaj kev cuam tshuam rau kev sib nqus zog thiab corrosion kuj.
Muaj ntau yam yuav tsum tau xav txog thaum tshawb nrhiav cov khoom sib nqus, thiab kev tiv thaiv corrosion yog ib qho tseem ceeb uas yuav tsum tau xav txog.
Ua ntej, Tam sim no cov khoom lag luam muaj zog tshaj plaws nyob rau hauv kev lag luam yog Ndfeb hlau nplaum, tab sis vim lawv cov ntsiab lus hlau siab, lawv kuj tsis tshua muaj kev puas tsuaj rau qhov chaw ntub dej, yog li yuav luag txhua zaus coated ua ntej siv.
Thib ob, Samarium cobalt hlau nplaum, zoo li Ndfeb hlau nplaum, muaj nyob rau hauv lub ntiaj teb tsis tshua muaj tsev neeg thiab muaj kev tiv thaiv corrosion ntau dua txawm tias tsis muaj coated. Qhov no yog vim hais tias feem ntau ntawm cov hlau siv nyob rau hauv neodymium hlau nplaum yog hloov los ntawm cobalt, uas tsis hnov mob nrog dej, yog li samarium cobalt hlau nplaum yog dav siv nyob rau hauv offshore ua hauj lwm.Koj yuav pom tau hais tias ib co samarium cobalt hlau nplaum yuav muaj ib tug txheej, feem ntau rau aesthetic. lub hom phiaj lossis rau cov laj thawj tshwj xeeb, xws li adhesion lossis sterility.
Thirdly, Ob leeg aluminium-nickel-cobalt hlau nplaum thiab ferrite hlau nplaum yog paub txog lawv cov corrosion kuj, txawm hais tias lawv tsis muaj tib qib sib nqus li tsawg-lub ntiaj teb samarium cobalt hlau nplaum thiab Ndfeb hlau nplaum.Qee qib ntawm txhuas-nickel-cobalt hlau nplaum muaj. Cov kab ntau ntawm cov hlau, yog li qee qhov me ntsis saum npoo corrosion yuav tshwm sim dhau sijhawm yog tias raug dej. Txawm li cas los xij, nickel-cobalt alloys ua tau zoo heev thaum raug lwm cov roj nplua nyeem, xws li roj, cov kuab tshuaj lossis cawv.
Plaub, ferrite hlau nplaum yog ua los ntawm hlau oxide, yog li lawv tsis corrode txawm tias thaum submerged nyob rau hauv dej.Vim lawv unparalleled corrosion kuj, ferrite hlau nplaum yog tsis tshua muaj coated, tab sis vim hais tias ferrite yog ib tug plua plav khoom, ib co daim ntaub ntawv yuav tsum tau ib co kev kho deg kom tsis txhob. hmoov av diffusion.
