1. Isingeniso se-Titanium kanye neMagnetism

I-Titanium iyisici esibalulekile embonini yesimanje, eyaziswa ngamandla ayo, isisindo esilula, nokumelana nokugqwala. Ukuqonda izici kazibuthe ze-titanium kubalulekile ekusebenzeni kwayo okuhlukahlukene endaweni ye-aerospace, imithi, i-electronics, neminye imikhakha. Lo mhlahlandlela obanzi uhlola izakhiwo, ukwakheka kwe-athomu, uzibuthe we-titanium, kanye nokusetshenziswa kwayo kuzo zonke izimboni ezahlukene.

 

1.1 Uhlolojikelele lwe-Element Titanium

I-Titanium, enophawu lwamakhemikhali u-Ti kanye nenombolo ye-athomu engu-22, iyinsimbi eguquguqukayo edume ngezinga layo eliphezulu lamandla nesisindo nokumelana nokugqwala okuhle kakhulu. Iyingxenye yesishiyagalolunye egcwele kakhulu oqweqweni Lomhlaba, etholakala kumaminerali afana ne-ilmenite ne-rutile. I-Titanium yaziswa kakhulu ezimbonini ezidinga izinto ezikwazi ukumelana nezimo ezinzima ngaphandle kokuwohloka.

 

1.2 Izimiso Eziyisisekelo Zezibuthe

I-Magnetism isuka ekuhambeni kwamashaji kagesi, ngokuvamile afaka ama-electron ngaphakathi kwama-athomu. I-magnetism yezinsimbi ihlukaniswa ngokuyinhloko ngezinhlobo ezintathu:

I-Ferromagnetism: Izinsimbi ezifana nensimbi, i-cobalt, ne-nickel zibonisa i-ferromagnetism, lapho izikhathi kazibuthe zama-athomu ziqondana ohlangothini olufanayo, zidale insimu enamandla kazibuthe.

I-Paramagnetism: Itholakala ezinsimbi ezifana ne-aluminium neplatinamu, lapho izikhathi zikazibuthe zama-athomu zihambisana nendawo kazibuthe yangaphandle, kodwa impahla ilahlekelwa uzibuthe wayo uma insimu isisusiwe.

I-Diamagnetism: Izinto ezifana nekhopha, i-zinc, negolide zibonisa i-diamagnetism, lapho zenza khona inkambu kazibuthe ephikisayo lapho zivezwe endaweni kazibuthe yangaphandle, okuholela kumandla angenamandla anyanyekayo.

 

2. Ukucushwa kwe-elekthronikhi kwe-titanium

 

2.1 Ukuqonda ukwakheka kwe-athomu ye-titanium kuyisihluthulelo sokuqonda uzibuthe wayo.

Ukucushwa kwe-electron ye-titanium yi-[Ar] 3d² 4s². Lesi sakhiwo sibonisa ukuthi i-titanium inama-electron amabili angabhanqiwe kuma-orbitals angu-3d, athinta izici zayo kazibuthe.

 

2.2 Ukwakheka kwekristalu nokuhlanganisa

I-Titanium icwebezela ngezindlela ezimbili: isakhiwo esine-hexagonal close-packed (hcp) (esibizwa nge-α-titanium) kanye nesakhiwo esigxile emzimbeni se-cubic (bcc) (esibizwa nge-β-titanium). Isigaba se-alpha sizinzile emazingeni okushisa aphansi, kuyilapho isigaba se-beta sizinzile emazingeni okushisa aphezulu. Uhlobo lwebhondi kanye nesakhiwo sekristalu kuthinta indlela ama-athomu asebenzisana ngayo nezinkundla kazibuthe.

 

2.3 Umthelela wesakhiwo se-athomu kumagnetism

Isakhiwo se-athomu ye-titanium kanye nokuba khona kwama-electron angabhanqiwe kuma-orbitals angu-3d kuholela ekuziphatheni kwayo okubuthakathaka kwe-paramagnetic. Ngokungafani nezinsimbi ze-ferromagnetic, i-titanium ayinaso isikhathi esibalulekile sikazibuthe, okusho ukuthi ayikhangwa kakhulu odonsa.

 

Ingabe i-titanium magnetic?

 

3. I-Magnetism ye-titanium ehlanzekile

 

3.1 I-titanium ehlanzekile i-paramagnetic.

I-titanium ehlanzekile i-paramagnetic, okusho ukuthi inokukhanga okubuthakathaka kukazibuthe. Kodwa-ke, lokhu kukhanga kubuthakathaka kakhulu futhi ngokuvamile kubhekwa njengokungeyona i-magnetic ngezinjongo ezingokoqobo.

 

3.2 Incazelo ye-paramagnetism kanye nencazelo ye-titanium magnetism

I-Paramagnetism yenzeka lapho ama-electron angabhanqiwe entweni eqondanisa nenkundla kazibuthe yangaphandle kodwa engasakugcini lokhu kuqondanisa uma insimu isisusiwe. Ku-titanium, ama-electron angabhanqiwe kuma-orbitals angu-3d ahambisana nenkundla kazibuthe, kodwa lo mphumela mncane uma uqhathaniswa nezinto ze-ferromagnetic.

Izinsimbi ze-Ferromagnetic (isb. iron, nickel)

 

Izinsimbi ze-Ferromagnetic ezifana ne-iron ne-nickel zinamandla kazibuthe ngenxa yokuhlelwa kwezikhathi zawo kazibuthe we-athomu. Lezi zinsimbi zihlala zikazibuthe ngisho nangemva kokuba insimu yangaphandle kazibuthe isusiwe.

 

Izinsimbi zeParamagnetic (isb i-aluminium, i-magnesium)

 

Izinsimbi zeParamagnetic ezifana ne-aluminium ne-magnesium zibonisa amandla kazibuthe afana ne-titanium. Bakhangwa yizinkundla kazibuthe kodwa abagcini uzibuthe.

 

Izinsimbi ze-diamagnetic (isb. ithusi, i-zinc, igolide)

 

Izinsimbi ze-diamagnetic ezifana nethusi, i-zinc negolide zixoshwa amandla kazibuthe. La mandla anyanyekayo abuthakathaka kakhulu futhi ngokuvamile awabonakali ngaphandle kwamathuluzi abucayi.

 

4.Titanium ingxubevange kanye uzibuthe

I-Titanium ivamise ukuxutshwa nezinye izakhi ukuze kuthuthukiswe izakhiwo zayo ezinhlelweni ezithile. Lawa ma-alloys angathinta izakhiwo kazibuthe ze-titanium.

 

Ama-alloys ajwayelekile e-titanium (njengeI-Ti-6Al-4V, Ti-3Al-2.5V)

 

I-Ti-6Al-4V: Le alloy yaziwa ngamandla ayo aphezulu, isisindo esilula, kanye nokumelana nokugqwala okuhle kakhulu. Isetshenziswa kabanzi emkhakheni we-aerospace kanye nezokwelapha.

I-Ti-3Al-2.5V: Enye i-alloy edumile enamandla amahle kanye ne-ductility esetshenziswa ku-aerospace kanye nezimboni zezimoto.

Umthelela wezakhi ze-alloying kuzakhiwo kazibuthe

 

Ukusebenzisa i-titanium ngezakhi ezifana ne-aluminium ne-vanadium kungashintsha izici zayo kazibuthe. Isibonelo, ukwengeza i-aluminium kungakhuphula ukuziphatha kwe-paramagnetic, kuyilapho ezinye izici zingase zethule umzuzu omncane ozibuthe.
