Ingaruka zo gucumura kumiterere ya zirconia ceramics

Nkubwoko bwibikoresho bya ceramic, zirconium ifite imbaraga nyinshi, gukomera kwinshi, kurwanya neza kwambara, aside na alkali, kurwanya ubushyuhe bwinshi nibindi byiza bihebuje. Usibye kuba yarakoreshejwe cyane mu nganda, hamwe n’iterambere rikomeye ry’inganda z’amenyo mu myaka yashize, ubukorikori bwa zirconiya bwabaye ibikoresho by’amenyo kandi bishobora gukurura abashakashatsi benshi.

Uburyo bwo gucumura

Uburyo gakondo bwo gucumura ni ugushyushya umubiri binyuze mumirasire yubushyuhe, gutwara ubushyuhe, guhuza ubushyuhe, kuburyo ubushyuhe buva hejuru ya zirconiya kugera imbere, ariko ubushyuhe bwumuriro wa zirconi ni bubi kuruta ubwa alumina nibindi bikoresho byubutaka. Mu rwego rwo gukumira gucika guterwa nubushyuhe bwumuriro, umuvuduko wubushyuhe gakondo uratinda kandi igihe ni kirekire, bigatuma ukwezi kuzenguruka kwa zirconi birebire kandi igiciro cyumusaruro ni kinini. Mu myaka yashize, kunoza ikoranabuhanga ryo gutunganya zirconi, kugabanya igihe cyo gutunganya, kugabanya igiciro cy’umusaruro, no gutanga ibikoresho by’amenyo bya zirconi y’amenyo ya ceramic byabaye intandaro y’ubushakashatsi, kandi gucumura microwave nta gushidikanya ko ari uburyo bwo gucumura.

Byagaragaye ko gucumura microwave hamwe no guhindagurika k'umuvuduko w'ikirere nta tandukaniro rikomeye bigira ku ngaruka za kimwe cya kabiri cyinjira no kwambara. Impamvu nuko ubucucike bwa zirconiya bwabonetse mugucumura microwave busa nubwa sinteri isanzwe, kandi byombi ni gucumura cyane, ariko ibyiza byo gucumura microwave nubushyuhe buke, umuvuduko mwinshi nigihe gito cyo gucumura. Nyamara, umuvuduko wubushyuhe bwikigereranyo cyumuvuduko wikirere uratinda, igihe cyo gucumura ni kirekire, kandi igihe cyo gucumura ni 6-11h. Ugereranije no guhindagura umuvuduko usanzwe, gucumura microwave nuburyo bushya bwo gucumura, bufite ibyiza byigihe gito cyo gucumura, gukora neza no kuzigama ingufu, kandi birashobora kunoza microstructure yububumbyi.

Bamwe mu bahanga bemeza kandi ko zirconi nyuma yo gucumura microwave ishobora gukomeza icyiciro cya tequartet cyoroshye, bishoboka kubera ko ubushyuhe bwihuse bwa microwave bushobora kugera ku kwihuta kwinshi kwibikoresho ku bushyuhe buke, ingano yingano ni ntoya kandi ihwanye n’iy'umuvuduko ukabije w’umuvuduko, munsi ya Ingano ikomeye yo guhindura icyiciro cya t-ZrO2, ifasha kubungabunga ibishoboka byose muburyo bwimiterere yubushyuhe bwicyumba, kuzamura imbaraga nubukomezi bwibikoresho byubutaka.

Inzira ebyiri zo gucumura

Ububiko bworoshye bwa zirconia ceramics bushobora gutunganywa gusa nibikoresho byo gutema emery kubera ubukana nimbaraga nyinshi, kandi igiciro cyo gutunganya ni kinini kandi igihe ni kirekire. Kugirango ukemure ibibazo byavuzwe haruguru, rimwe na rimwe ceramics zirconia izakoreshwa muburyo bubiri bwo gucumura, nyuma yo gushiraho umubiri wa ceramic no gucumura kwambere, amplification ya CAD / CAM ikora muburyo bwifuzwa, hanyuma igacengera kubushyuhe bwa nyuma bwo gucumura kugirango ikore ibikoresho byuzuye.

Byagaragaye ko inzira ebyiri zo gucumura zizahindura kinetic kinetic ya ceramika ya zirconi, kandi bizagira ingaruka zimwe mubucucike bwicyaha, imiterere yubukanishi na microstructure ya ceramika ya zirconi. Imiterere yubukanishi bwimashini zirconia ceramics yacumuye iyo ubucucike buruta ubwiza kabiri. Imbaraga za biaxial zunamye hamwe no kuvunika gukomera kumashini ya zirconia ceramics yimashini yacumuye iyo compact irenze iyo yacumuye kabiri. Uburyo bwo kuvunika bwibanze bwa zirconia ceramics ni transgranular / intergranular, kandi imyigaragambyo irasa neza. Uburyo bwo kuvunika bwa ceramics zirconia inshuro ebyiri zicumuye cyane cyane kuvunika hagati yimibumbe, kandi inzira yo gucika irarenze. Ibiranga uburyo bwo kuvunika hamwe nibyiza kuruta uburyo bworoshye bwo kuvunika.

Icyuho

Zirconiya igomba gucumurizwa mubidukikije, mugihe cyo gucumura bizabyara umubare munini wibibyimba, kandi mugihe cyimyuka, ibibyimba byoroshye gusohora mumiterere ya elegitoronike yumubiri wa farashi, bikazamura ubwinshi bwa zirconi, bityo bikongera igice cya permeability hamwe nubukanishi bwa zirconi.

Igipimo cy'ubushyuhe

Muburyo bwo gucumura kwa zirconi, kugirango tubone imikorere myiza nibisubizo byateganijwe, hagomba gushyirwaho igipimo gito cyo gushyushya. Igipimo kinini cyo gushyushya gituma ubushyuhe bwimbere bwa zirconi butaringaniye iyo bugeze ku bushyuhe bwa nyuma bwo gucumura, biganisha ku kugaragara kw'imitsi no gukora imyenge. Ibisubizo byerekana ko hamwe no kwiyongera k'ubushyuhe, igihe cyo gutegera kwa kirisiti ya zirconi kigabanuka, gaze hagati ya kirisiti ntishobora gusohoka, kandi ububobere buri muri kirisiti ya zirconi bwiyongera gato. Hamwe n'ubwiyongere bw'ubushyuhe, umubare muto wa kirisiti ya monoclinike itangira kubaho mugice cya tetragonal ya zirconi, kizagira ingaruka kumiterere. Muri icyo gihe, hamwe no kwiyongera k'ubushyuhe, ibinyampeke bizaba polarize, ni ukuvuga kubana kw'ibinyampeke binini kandi bito byoroshye. Igipimo cyo gushyushya gahoro gifasha gukora ibinyampeke byinshi, byongera semipermeability ya zirconia.
