I-Nitinol iyingxube yenkumbulo yomumo. I-Shape memory alloy iyingxubevange ekhethekile engabuyisela ngokuzenzakalelayo ukuguqulwa kwayo kwepulasitiki ekumeni kwayo kwasekuqaleni ezingeni lokushisa elithile, futhi inepulasitiki enhle.
Izinga lokunwetshwa kwalo lingaphezu kwama-20%, impilo yokukhathala ifinyelela ezikhathini eziyi-7 ku-1 * 10, izici zokudambisa ziphakeme izikhathi eziyi-10 kuneziphethu ezivamile, futhi ukumelana nokugqwala kwayo kungcono kunensimbi engagqwali yezokwelapha yamanje, ngakho-ke ingahlangabezana nezidingo zezinhlobonhlobo ezahlukahlukene. ubunjiniyela kanye nezicelo zezokwelapha, futhi luhlobo lwezinto ezinhle kakhulu zokusebenza.
Ngokungeziwe kumsebenzi wenkumbulo yomumo oyingqayizivele, ama-alloys enkumbulo nawo anezici ezinhle kakhulu ezifana nokumelana nokugqokwa, ukumelana nokugqwala, ukumanzisa okuphezulu kanye nokunwebeka okukhulu.
(I) Ukuguqulwa Kwesigaba kanye Nezakhiwo Ze-Nickel-Titanium Alloys
Njengoba igama liphakamisa, i-Ni-Ti alloy iyingxube kanambambili eyakhiwe nge-nickel ne-titanium, ekhona ngezigaba ezimbili ezihlukene ze-crystal structure, i-austenite ne-martensite, ngenxa yokushintsha kwezinga lokushisa nokucindezela komshini. Ukuhleleka kokuguqulwa kwesigaba se-Ni-Ti alloy lapho ukupholisa kuyisigaba somzali (isigaba se-austenite) - isigaba sika-R - isigaba se-martensite. Isigaba sika-R siyi-rhombic, i-austenite yisimo lapho izinga lokushisa liphakeme (likhulu kunokufana: okungukuthi, izinga lokushisa lapho i-austenite iqala), noma i-de-loaded (amandla angaphandle asusa Ukuvala), i-cubic, kanzima. Umumo uzinzile. Isigaba se-martensite sisezingeni lokushisa eliphansi kakhulu (elingaphansi kwe-Mf: okungukuthi, izinga lokushisa lokuphela kwe-martensite) noma ukulayisha (kucushwe amandla angaphandle) lapho isimo, i-hexagonal, i-ductile, iphindaphinda, izinzile kancane, ijwayele ukuguqulwa.
(B) izakhiwo ezikhethekile ze-nickel-titanium alloy
1, izici zenkumbulo yomumo (inkumbulo yomumo)
2. I-Superelasticity (i-superelasticity)
3, Ukuzwela ekushintsheni kwezinga lokushisa emgodini womlomo.
4. Ukumelana nokugqwala:
5, Anti-toxicity:
6, Soft orthodontic force
7, Izakhiwo ezinhle zokumunca ukushaqeka
