Zirconia ceramics vs silicon carbide ceramics: vim li cas cov lag luam siab nyiam silicon carbide?

Hauv thaj chaw ntawm cov ntaub ntawv lag luam niaj hnub, zirconia ceramics thiabsilicon carbide ceramicsyog ob qho tib si cov ntaub ntawv ua tau zoo uas tau nyiam ntau lub siab. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb hauv lawv cov yam ntxwv, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub xws li kub siab, hnav tsis kam, thiab corrosion tsis kam. Silicon carbide ceramics qhia txog cov txiaj ntsig zoo dua. Tsab xov xwm no yuav tshuaj xyuas qhov tsis tuaj yeem hloov pauv ntawm silicon carbide ceramics los ntawm kev siv tiag tiag.

1, Tus 'tub rog muaj peev xwm' ​​ntawm thaj chaw sib ntaus sib tua kub

Cov kev xav tau ruaj khov rau cov ntaub ntawv nyob rau hauv qhov kub siab yog qhov nyuaj heev. Thaum zirconia ceramics siab tshaj 1200 ℃, lawv cov qauv siv lead ua sab hauv yog qhov yooj yim hloov pauv, ua rau muaj kev hloov pauv ntim thiab txawm tias tawg, uas txwv lawv daim ntawv thov hauv cov chaw kub siab ntev. Silicon carbide ceramics tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv hauv cov huab cua inert siab tshaj 1350 ℃, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov cub tawg kub, kev tiv thaiv cua sov spacecraft, thiab lwm yam teb.

2, Hard core hnav-resistant, ntev dua lifespan

Zirconia ceramics paub txog lawv qhov kev tawv thiab tsim nyog rau cov ntawv thov uas xav tau kev tiv thaiv kev cuam tshuam, xws li cov cuab yeej txiav ceramic lossis cov pob qij txha cuav. Tab sis hauv cov xwm txheej kev lag luam uas raug kev sib txhuam mus sij hawm ntev thiab kev puas tsuaj ntawm cov khoom me me, cov yam ntxwv "superhard" ntawm silicon carbide (Mohs hardness 9.5, thib ob tsuas yog pob zeb diamond) yog qhov tseem ceeb dua.

Piv txwv li, hauv cov phaj tiv thaiv kev hnav-resistant ntawm cov tshuab mining thiab cov khoom sib khi ntawm cov twj tso kua tshuaj, lub neej ua haujlwm ntawm silicon carbide tuaj yeem ncav cuag ntau zaus ntawm zirconia, txo cov nqi kho khoom siv.

3, Kev tiv thaiv corrosion: nyuaj heev ib puag ncig

Cov zirconia ceramics tej zaum yuav raug xeb hauv cov kua qaub muaj zog lossis cov pa kub siab, thaum silicon carbide muaj zog heev rau feem ntau cov tshuaj corrosive. Nws tsim nyog hais tias nyob rau hauv qhov chaw oxidizing kub siab, ib txheej tiv thaiv silicon dioxide ntom ntom yuav tsim rau ntawm qhov chaw ntawm silicon carbide, ntxiv qeeb cov txheej txheem oxidation ntawm cov khoom siv. Lub tshuab "kev tiv thaiv tus kheej" no ua rau nws ua tau zoo heev hauv cov chaw corrosive xws li cov pa roj flue desulfurization thiab cov khoom siv kho pa tawm.

xaus lus

Zirconia ceramics nyob hauv kev kho mob thiab cov neeg siv khoom vim lawv lub zog zoo heev, thaum silicon carbide ceramics tau dhau los ua "cov khoom siv zoo tshaj plaws" ntawm cov lag luam siab xws li lub zog, tshuaj lom neeg, thiab semiconductor vim lawv qhov kub thiab txias ruaj khov, tiv taus kev hnav zoo, thiab tshuaj lom neeg tsis muaj zog. Nrog rau kev txhim kho thev naus laus zis, kev siv silicon carbide tshiab tau nthuav dav nws cov ciam teb, muab cov kev daws teeb meem txhim khu kev qha rau kev txhim kho kev lag luam.
