Nyob rau hauv lub ntiaj teb no precision ntawm kev lag luam niaj hnub, me me deformations ntawm cov ntaub ntawv feem ntau txiav txim siab qhov kawg ntawm cov khoom.Silicon carbide ceramics, nrog rau lawv cov khoom tshwj xeeb ntawm lub cev, tab tom dhau los ua "tus neeg saib xyuas nruj" hauv kev tsim khoom siab kawg. Cov khoom siv ceramic siab tshaj qhov tshwj xeeb tsis kam rau deformation yog redefining cov qauv kev ua tau zoo rau cov khoom siv precision.
1 、 Rigid scientific code
Lub elastic modulus ntawm cov khoom yog zoo li tus pas ntsuas rigidity, ncaj qha txiav txim siab nws lub peev xwm los tiv thaiv deformation nyob rau hauv kev ntxhov siab. Lub elastic modulus ntawm silicon carbide ceramics yog ntau tshaj li peb zaug ntawm cov hlau zoo tib yam, uas ua rau nws zoo ib yam li cov hlau reinforcement pob txha nyob rau hauv lub tsev thaum raug rau siab - txawm nyob rau hauv lub high-lub zog load ntawm cov khoom hnyav, lub deformation tsuas yog 1/4 ntawm cov ntaub ntawv hlau.
Qhov txawv tshaj plaw rigidity no tshwm sim los ntawm lub zog covalent daim ntawv cog lus nyob rau hauv cov khoom. Txhua cov pa roj carbon atom yog nruj nreem txuas rau plaub lub silicon atoms los ntawm kev sib cuam tshuam muaj zog, ua rau peb-dimensional network siv lead ua qauv. Thaum cov quab yuam sab nraud ua, cov qauv lattice ruaj khov no tuaj yeem cuam tshuam kev ntxhov siab thiab tswj kev deformation hauv micrometer ntau yam. Hauv cov teb xws li precision optical platforms thiab semiconductor manufacturing khoom uas muaj pes tsawg kam rau deformation, tus yam ntxwv no dhau los ua tus yuam sij kom ntseeg tau qhov tseeb.
2 、 Lub tswv yim ntawm cov khoom siv sib xyaw ua ke rigidity thiab yooj
Silicon carbide ceramics tsis tsuas yog nthuav tawm ultra-siab rigidity, tab sis kuj muaj cov kev ua tau zoo tshaj plaws:
1. Rigid tab sis tsis nkig: Nws lub zog dabtsi yog khoov siab tshaj ntawm cov hlau tshwj xeeb, thiab txawm tias nyob rau hauv siab sib npaug ntawm tus neeg laus ntxhw sawv ntawm ib ko taw (txog 400MPa), nws tseem tuaj yeem ua kom muaj kev ncaj ncees. Qhov kev sib xyaw ua ke ntawm lub zog siab thiab siab rigidity daws qhov teeb meem kev lag luam ntawm cov tsoos ceramics tsis yooj yim.
2. Thermal stability zoo li lub roob: Lub thermal expansion coefficient ntawm cov khoom tsuas yog 1/4 ntawm cov hlau, thiab qhov sib txawv ntawm qhov loj me me yog qhov sib txawv ntawm qhov kub ntawm 200 ℃. Ua ke nrog nws cov thermal conductivity zoo heev, nws tuaj yeem sib npaug ntawm qhov kub thiab txias gradients sai thiab tsis txhob deformation txuam los ntawm thermal stress.
3. Tsis deformation: Nyob rau hauv kev ntxhov siab tas mus li, qhov nkag ntawm silicon carbide yog ob qhov kev txiav txim siab qis dua li cov khoom siv hlau. Qhov no txhais tau hais tias txawm tias raug rau tib lub load rau kaum xyoo, nws cov kev hloov pauv tseem tuaj yeem tswj tau qis dua qhov ntsuas ntsuas ntsuas.
3, Rigid thev naus laus zis tus nqi
Lub peev xwm tshwj xeeb no los tiv thaiv deformation yog tsim kom muaj kev lag luam tshiab:
Nyob rau hauv satellite optical systems, xyuas kom meej tias daim iav tuav nanometer theem flatness nyob rau hauv huab cua sib txawv ntawm qhov chaw.
Tswj sub micron positioning raug ntawm cov lus tsa suab platform ntawm semiconductor wafer ua khoom siv thaum lub sijhawm ua haujlwm siab.
Tuav lub geometric stability ntawm cov qauv kaw ntawm lub siab chamber ntawm cov khoom siv tshawb nrhiav hauv hiav txwv sib sib zog nqus txawm tias nyob rau hauv kilometer qib dej siab.
Peb hloov cov khoom siv no kom zoo dua rau hauv kev sib tw thev naus laus zis los ntawm cov txheej txheem tshiab: siv cov txheej txheem tsim khoom los txhim kho cov khoom ntom ntom; Los ntawm kev siv cov thev naus laus zis patented, toughness yog txhim kho thaum tuav ultra-siab rigidity. Txhua batch ntawm cov ntaub ntawv tau dhau mus kuaj nruj kom ntseeg tau tias cov khoom xa tuaj tau raws li lossis ntau tshaj cov neeg siv khoom.
Niaj hnub no, raws li precision manufacturing txav mus rau lub nanoscale, silicon carbide ceramics yog txhais cov tub ntxhais nrhiav kev lag luam niaj hnub nrog nws "rigid philosophy" - siv qhov ruaj khov ntawm cov ntaub ntawv los txhawb kev tsim khoom tsis kawg. Qhov kev siv thev naus laus zis no, uas ua rau muaj kev txawj ntse ntawm cov ntaub ntawv kev tshawb fawb, yuav txuas ntxiv mus ntxiv lub zog tshiab ntawm "siv rigidity los kov yeej kev hloov pauv" rau hauv kev tsim khoom siv high-end.
