Abantu abaninzi bayamangaliswa kukufumanisa ukuba ayizizo zonke iintlobo zentsimbi ezinomtsalane. Enyanisweni, ezinye iintsimbi azinamatheli kwiimagnethi konke konke. Le propati ixabiseke kakhulu kumashishini afana nobunjineli baselwandle, ukulungiswa kokutya, izixhobo zonyango, kunye ne-elektroniki, apho kufuneka kuthintelwe ukuphazamiseka kwemagnethi okanye ukungcola.
Ngoko ke, luhlobo luni lwentsimbi oluyenzayounganamatheli kumagnethiImpendulo ikwisakhiwo sayo sangaphakathi kunye nokwakheka kwayo ngamakhemikhali. Kweli nqaku, siza kuchaza ukuba kutheni ezinye iintsimbi zingenamagnethi, zeziphi iiklasi ezilungileyo, kunye nendlela yokukhetha izinto ezifanelekileyo kwisicelo sakho. Njengomthengisi wentsimbi engagqwaliyo othembekileyo,I-SAKYSTELIbonelela ngoluhlu olupheleleyo lweentsimbi ezingenamagineti ezenzelwe ukubonelela ngokusebenza kakuhle, ukuthembeka, kunye nokumelana nokugqwala kwihlabathi liphela.
1. Ukuqonda Isizathu Sokuba Ezinye Iintsimbi Zinamathela Kumagnitshi
Ukuze siqonde ukuba yeyiphi intsimbi enganamatheliyo kwimagnethi, kufuneka siqale siqondekutheni uninzi lweentsimbi zinamandla ombane.
Intsimbi yenziwe ngentsimbi, enomtsalane ngokwemvelo ngenxa yayoityhubhikhi egxile emzimbeni (BCC)isakhiwo sekristale esivumela iidomeyini zemagnethi ukuba zilungelelane ngokulula.
Nangona kunjalo, xa kongezwa i-nickel okanye ezinye izinto ezidibanisa i-alloying, ulwakhiwo lwekristale luyatshintsha lube yi-ityhubhiki ejonge ubuso (FCC)ifomu, engavumeli ukulungelelaniswa kwemagnethi. Olu lulwakhiwo olufumaneka kwiiintsimbi ezingenasici ze-austenitic, eziziintlobo eziphambili zentsimbi ezingezizo ezemagnethi.
2. Isayensi yeMagnetism kwiNtsimbi Engagqwaliyo
Kukho iindidi ezintathu eziphambili zeentsimbi ezingenasici ezisekelwe kwisakhiwo sazo sekristale kunye nokuziphatha kwazo kwemagnethi:
-
Iintsimbi Ezingenazintsimbi Zase-Austenitic (Ezingezizo Ezinemagnethi):
Zinesakhiwo seFCC kunye nomxholo ophezulu we-nickel, nto leyo eyenza zingabi namandla ombane nokuba kumaqondo obushushu aphantsi. -
Iintsimbi zeFerritic Stainless (Magnetic):
Zinesakhiwo se-BCC kwaye zine-chromium kodwa zincinci okanye azinazo kwaphela i-nickel, nto leyo eyenza zibe namandla kakhulu. -
Iintsimbi zeMartensitic Stainless (Magnetic):
Zinekhabhoni eninzi kunye ne-chromium, ziyanyangeka ngobushushu, kwaye zinophawu olunamandla lwemagnethi.
Ngoko ke,iintsimbi ezingenasici ze-austeniticziintsimbi ezithimusa ukunamathela kumagnethikwimeko yabo ebotshelelweyo.
3. Iintsimbi ezinganamatheli kwiimagnethi
A. Uhlobo lwe-304 Stainless Steel
Intsimbi engagqwaliyo exhaphakileyo ehlabathini, i-304 ine-chromium eyi-18% kunye ne-nickel eyi-8%.
Ulwakhiwo lwayo luyi-austenitic ngokupheleleyo kwaye ngoko ke aluyi-magnetic. Nangona kunjalo, emva kokusebenza ngokubandayo okanye ukuwelda, inokuba nempendulo encinci yemagnethi ngenxa yokuguquka okuncinci ibe yi-martensite.
