Iyiphi Insimbi Engeyona I-Magnetic Evame Kakhulu?

Uma sicabanga ngezinsimbi, abantu abaningi bazihlanganisa ngokushesha ne-magnetism. Phela, izinto ezifana nensimbi, i-cobalt, ne-nickel zaziwa kakhulu ngezakhiwo zazo ezinamandla ze-magnetic. Kodwa-ke, akuzona zonke izinsimbi ezi-magnetic — empeleni, izinsimbi eziningana ezisetshenziswa kabanzi azisabelani nhlobo kumagnet. Lezi.izinsimbi ezingezona ezikazibutheidlala indima ebalulekile ezimbonini lapho ukuphazamiseka kukazibuthe, ukumelana nokugqwala, kanye nokungathathi hlangothi kukagesi kubalulekile khona.

Ngakho-ke, iyiphi insimbi engeyona enemagnethi evame kakhulu? Impendulo ithiinsimbi engagqwali ye-austenitic (ikakhulukazi i-SS 304)futhii-aluminium— zombili zisetshenziswa kabanzi kuzo zonke izimboni ngenxa yezakhiwo zazo ezihlukile. Kulesi sihloko, sizohlola ukuthi yiziphi izinsimbi ezingezona ezikagesi, kungani ziziphatha ngale ndlela, nokuthi zivame ukusetshenziswa kuphi.

Njengomhlinzeki womhlaba wonke,I-SAKYSTEELinikeza ububanzi obukhulu bezinsimbi ezingagqwali kanye nama-alloy angewona amagnetic ahlanganisa amandla, ukumelana nokugqwala, kanye nokuqina kwezicelo zezimboni ezithuthukile.

1. Ukuqonda i-Magneticism ku-Metals

Izakhiwo zikagesi zensimbi zincike ekutheniisakhiwo se-athomu— ikakhulukazi, ukuthi ama-electron ayo angavumelana yini ukuze akhe izizinda zamagnetic noma cha.

• Izinsimbi ZikaMazibuthe:Insimbi, i-cobalt, kanye ne-nickel — isakhiwo sazo se-athomu sivumela ama-electron angabhangqiwe ukuthi avumelane kalula, okudala ukukhanga okunamandla kwe-magnetic.

• Izinsimbi Ezingezona EzikaMagnetic:I-aluminium, ithusi, ithusi, i-lead, igolide, isiliva, kanye nezinsimbi ezingagqwali ze-austenitic — ukwakheka kwazo kwama-electron kuvimbela ukuhambisana, okuholela ekusebenzeni okuncane kakhulu noma okungenawo amandla kazibuthe.

Ngamagama alula,izinsimbi ezingezona ezikazibuthe azinamatheli kumazibuthengoba izakhiwo zabo zangaphakathi ze-athomu azikwazi ukusekela ukwakheka kwensimu yamagnetic.

2. Insimbi Engeyona Eyomlingo Evame Kakhulu: I-Aluminium

I-Aluminium (Al)iyinsimbi engeyona ene-magnetic evame kakhulu futhi esetshenziswa kabanzi emhlabeni.

Kungani i-Aluminium ingeyona i-Magnetic

Isakhiwo se-athomu se-aluminiyam asinawo ama-electron angaxhunywanga egobolondweni laso langaphandle, okusho ukuthi ayikwazi ukukhiqiza amandla ayo kazibuthe. Ngisho noma ibekwe eduze kwe-magnet, i-aluminiyam ayibonisi ukukhanga okubonakalayo noma ukucasula.

Izakhiwo Eziyinhloko ze-Aluminium

• Okungeyona i-magnetic kanye nokungashisi:Kuphephile ukusebenzisa eduze kwemishini ebucayi noma ezindaweni eziqhumayo.

• Ilula:Cishe ingxenye eyodwa kwezintathu yesisindo sensimbi, okwenza ibe yindawo ekahle kakhulu yokuhamba ngezindiza kanye nezokuthutha.

• Ukumelana Nokugqwala:Yakha ungqimba lwe-oxide yemvelo oluvikela ekugqwaleni.

• Iqhuba Kakhulu:Kuhle kakhulu ekusetshenzisweni kukagesi nokushisa.

Ukusetshenziswa kwe-Aluminium

• Izingxenye zezindiza nezindiza

• Izingxenye zezimoto nezasolwandle

• Izintambo zikagesi kanye nezintambo zokudlulisa

• Ukupakisha ukudla kanye namathini eziphuzo

• Amaphaneli okwakha kanye nohlaka lwamafasitela

Ngenxa yokuhlanganiswa kwayo kwesisindo esilula, ukumelana nokugqwala, kanye nezakhiwo ezingezona ezikagesi,i-aluminium iyinsimbi engeyona ene-magnetic esetshenziswa kakhulu emhlabeni.

3. Izinsimbi Ezingagqwali Zase-Austenitic – Insimbi Engavamile Kakhulu Engeyona I-Magnetic

Nakuba i-aluminium ihola phakathi kwezinsimbi ngokuvamile,izinsimbi ezingenasici ze-austeniticyizona ezivame kakhuluizinto ezisekelwe kunsimbi ezingezona ezikagesiesetshenziswa ezicelweni zezimboni nezobunjiniyela.

Kungani Izinsimbi Ezingagqwali Zase-Austenitic Zingewona Umagnetic

Lezi zinsimbi zine-i-cubic egxile ebusweni (i-FCC)isakhiwo sekristalu esiqiniswe yi-nickel. Lesi sakhiwo sivimbela ukuhambisana kwezizinda zamagnetic, okwenza zingabi namandla kagesi esimweni sazo esincishisiwe.

Amabanga Ajwayelekile

• I-SS 304 (18-8 Insimbi Engagqwali):I-18% chromium, 8% nickel — ukumelana okuhle kakhulu nokugqwala, ukuhlanzeka, kanye nokungasebenzisi amandla kazibuthe.

• I-SS 316:Iqukethe i-molybdenum yokumelana okuthuthukisiwe nama-chloride kanye nezindawo zasolwandle.

• I-SS 321 kanye ne-SS 310:Amabanga azinzile futhi asezingeni lokushisa eliphezulu, futhi awekho magnetic.

• I-SS 904L:I-alloy enamandla kakhulu ye-austenitic ehlala ingeyona i-magnetic ngokuphelele ngisho nangemva kokusebenza okubandayo.

Izicelo

• Imishini yokucubungula ukudla kanye neziphuzo

• Imishini yezokwelapha neyelebhu

• Izakhiwo zasemanzini kanye nasogwini lolwandle

• Izitshalo zamakhemikhali nezemithi

• Ukuhlobisa izakhiwo

Ngakho-ke, uma kukhulunywa ngemikhiqizo yensimbi,Insimbi engagqwali ye-SS 304kubhekwainsimbi engeyona eyomagnetic evame kakhuluisetshenziswa emhlabeni wonke.

4. Ezinye Izinsimbi Ezingezona EzikaMagnetic

Ngaphandle kwe-aluminium kanye nensimbi engagqwali ye-austenitic, ezinye izinsimbi eziningana nazo zibonisa izakhiwo ezingezona ezikagesi:

A. Ithusi (Cu)

• Ukuqhuba kahle kukagesi nokushisa.

• Isetshenziswa kakhulu ezinhlelweni zokuxhuma izintambo, ama-motor, kanye namapayipi.

• Ayinamandla kazibuthe, ayigqwali, futhi ingaphinde isetshenziswe.

B. Ithusi (I-Cu-Zn Alloy)

• Ingxubevange yethusi ne-zinc; imelana kakhulu nokugqwala.

• Kusetshenziswa ekufakweni, amavalvu, izinsimbi zomculo, kanye nezinto zasolwandle.

• Akuyona i-magnetic futhi kulula ukuyilungisa.

C. Ithusi (I-Cu-Sn Alloy)

• Ingxubevange eqinile futhi engeyona i-magnetic yethusi ne-tin.

• Ivame ukusetshenziswa kuma-bearings, bushings, kanye nezithombe eziqoshiwe.

D. I-Titanium (i-Ti)

• Iqinile, ilula, futhi ayinamandla okudonsa.

• Kusetshenziswa ezindiza, ezifakelweni zezokwelapha, kanye nasezisetshenzisweni zezimboni ezisezingeni eliphezulu.

E. I-Lead (Pb)

• Iqinile futhi ayinamandla kagesi; isetshenziswa ekuvikeleni imisebe kanye namabhethri.

F. I-Zinc, Igolide, Nesiliva

• Izinsimbi eziyigugu neziyisisekelo ezinokumelana okuhle kakhulu nokugqwala futhi ezingenazo izakhiwo zikagesi.

5. Indlela Yokuhlola Uma Insimbi Ayinayo I-Magnetic

Ukuhlola i-magnetism kulula:

• Sondeza i-magnet encane eduze kobuso bensimbi.

  • Akukho okukhangayo:Insimbi ayinamandla kazibuthe.

  • Ukukhanga okubuthakathaka:I-magnetic eyingxenye (isakhiwo se-alloy esingenzeka).

  • Ukukhanga okunamandla:Izinsimbi ze-magnetic (insimbi, i-ferritic, noma i-martensitic).

Izinto zokucwaninga ezifanaamamitha okuvumela amandla kazibutheinganikeza izilinganiso ezinembile, ikakhulukazi ezilinganisweni zensimbi engagqwali lapho amandla okuzibuthe amancane angavela khona ngemva kokusebenza ngokubanda.
