Silicon carbide ceramics: yakozwe neza 'urushinge rwo gutunganya inyanja'

Mwisi yuzuye neza yinganda zigezweho, ihindagurika rito ryibikoresho akenshi rigena imikorere yanyuma yibikoresho.Silicon carbide ceramics, hamwe nimiterere yihariye yumubiri, bahinduka "ingirakamaro umurinzi" murwego rwohejuru rwo gukora inganda. Ibikoresho bya ceramic byateye imbere bidasanzwe byo kurwanya ivugurura ni ugusobanura ibipimo ngenderwaho kubikoresho byuzuye.

Modulike ya elastike yibintu ni nkumutegetsi wo gupima ubukana, agena neza ubushobozi bwayo bwo kurwanya ihinduka ryimiterere. Modulus ya elastike ya silicon carbide ceramics yikubye inshuro zirenze eshatu icyuma gisanzwe, ibyo bigatuma bisa na skeleton yo gushimangira ibyuma mumazu iyo ihuye nigitutu - nubwo haba hari umutwaro mwinshi wibikoresho biremereye, deformasiyo ni 1/4 cyibikoresho byibyuma.
Uku gukomera kudasanzwe guturuka kumurongo ukomeye wa covalent imiterere yibikoresho. Buri atome ya karubone ihujwe cyane na atome enye za silicon binyuze mumikoranire ikomeye, ikora imiyoboro itatu-ya sisitemu ya kristu. Iyo imbaraga zo hanze zikora, iyi miterere ihamye irashobora gukwirakwiza neza guhangayika no kugenzura ihinduka ryimiterere ya micrometero. Mubice nkibikoresho bya optique hamwe nibikoresho byo gukora semiconductor bifite kwihanganira zeru kubihindura, ibi biranga biba urufunguzo rwo kwemeza ukuri.
2 philosophy Filozofiya y'ibikoresho ihuza gukomera no guhinduka
Silicon carbide ceramics ntigaragaza gusa ubukana bukabije, ariko kandi ifite imikorere itangaje:
1. Rigid ariko idacogora: Imbaraga zayo zunama zirenze iz'icyuma kidasanzwe, ndetse no mu gitutu gihwanye n’inzovu ikuze ihagaze ku kirenge kimwe (hafi 400MPa), irashobora gukomeza ubusugire bw’imiterere. Uku guhuza imbaraga nyinshi hamwe no gukomera bikemura ikibazo cyinganda zubutaka gakondo bworoshye.
. Ufatanije nubushuhe buhebuje bwumuriro, birashobora kuringaniza byihuse ubushyuhe bwikirere kandi bikirinda kwirundanya kwimiterere biterwa nubushyuhe bwumuriro.
3. Ibi bivuze ko niyo byakorerwa umutwaro umwe mumyaka icumi, imiterere yabyo irashobora kugenzurwa munsi yumupaka wibikoresho.

3 value Agaciro kikoranabuhanga
Ubu bushobozi budasanzwe bwo kurwanya ivugurura burimo gukora inganda nshya:
Muri sisitemu ya optique ya sisitemu, menya neza ko indorerwamo ikomeza urwego rwa nanometero munsi yubushyuhe bukabije mumwanya.
Komeza sub micron ihagaze neza yibikorwa byimikorere ya semiconductor wafer ibikoresho byo gutunganya mugihe cyihuta.
Komeza uburinganire bwa geometrike yuburyo bufunze urugereko rwumuvuduko wibikoresho byubushakashatsi bwimbitse-nyanja ndetse no munsi ya kilometero yumuvuduko wamazi.
Duhindura iyi nyungu yibintu muburyo bwo guhatanira ikoranabuhanga binyuze muburyo bushya: gukoresha uburyo bugezweho bwo gukora kugirango twongere ubwinshi bwibintu; Ukoresheje ikoranabuhanga ryateye imbere, gukomera birongerwaho mugihe gikomeza ultra-high rigidity. Buri cyiciro cyibikoresho bikorerwa ibizamini bikomeye kugirango ibicuruzwa byatanzwe byujuje cyangwa birenze ibyo abakiriya bakeneye.
Uyu munsi, mugihe inganda zuzuye zigenda zerekeza kuri nanoscale, ceramika ya silicon karbide isobanura intego nyamukuru yo gukurikirana inganda zigezweho hamwe na "filozofiya itajenjetse" - ikoresha ituze ryuzuye ryibikoresho kugirango ishyigikire ibintu bitagira ingano byo gukora. Iri terambere mu ikoranabuhanga, rikubiyemo ubwenge bwibikoresho bya siyansi, bizakomeza gutera imbaraga zo guhanga udushya two "gukoresha imbaraga zo gutsinda ibintu byoroshye" mu bikoresho byo mu rwego rwo hejuru.
