Hauv chav huv ntawm lub Hoobkas semiconductor, cov wafers dub ci ntsa iab nrog cov xim hlau yog ua tiav ib qho los ntawm ib qho; Nyob rau hauv lub combustion chamber ntawm lub spacecraft cav, ib tug tshwj xeeb ceramic tivthaiv yog nyob rau hauv ib tug 2000 ℃ nplaim taws kev cai raus dej. Tom qab cov xwm txheej no, muaj cov khoom siv hu ua "kev lag luam dub gemstone" -silicon carbide ceramics.
Cov khoom siv superhard, thib ob tsuas yog pob zeb diamond hauv hardness, yog ntsiag to rewriting cov cai ntawm high-end manufacturing. Nws tuaj yeem tiv taus cov hluav taws xob muaj zog ntawm cov hluav taws xob hluav taws xob, xa hluav taws xob sai sai ntawm lub zog tshiab, thiab dhau los ua cov khoom siv hluav taws xob kub ntawm 5G hauv paus chaw nres tsheb. Tab sis tom qab qhov kev ua tau zoo zoo li no, muaj qhov kev sib tw uas tsis tuaj yeem lees paub: yuav ua li cas kho cov khoom "tsis zoo"?
Cov khoom ntawm cov khoom txiav txim siab ua cov nyom
Kev ua haujlwm nyuaj ntawm silicon carbide zoo li cov qauv ntawm cov iav. Nws hardness yog 3-5 npaug ntawm cov ceramics zoo tib yam. Cov cuab yeej txiav cov pa zoo li carving steel daim hlau nrog chalk, uas tsis tsuas yog muaj kev ua haujlwm tsawg tab sis kuj yooj yim tawg ntawm lub tshuab ua haujlwm. Dab tsi yog qhov nyuaj dua yog tias cov khoom siv no muaj qhov ua kom pom tseeb, thiab qhov yuam kev me me tuaj yeem ua rau nws zoo li biscuit, tshwj xeeb tshaj yog rau cov khoom siv precision nrog lub thickness tsawg dua 1 millimeter, cov txheej txheem ua haujlwm tuaj yeem piav qhia raws li kev seev cev ntawm cov hlau hlau.
Txoj Kev Tshaj Tawm ntawm Kev Tsim Kho Niaj Hnub No
Tau ntsib nrog cov teeb meem no, engineers tau tsim peb qhov loj "txoj kev ntawm cov ntaub ntawv taming":
1. Pwm shaping thev naus laus zis - cov txheej txheem kub nias zoo ib yam li ua cov ncuav mog qab zib, uas tso cai rau silicon carbide hmoov "obediently conform" nyob rau hauv qhov kub thiab txias, ua rau nws tshwj xeeb tshaj yog haum rau manufacturing standardized industrial txiav cov cuab yeej. Lub tshuab no zoo li muab pwm shackles rau ntawm cov ntaub ntawv, shaping cov duab geometric tsis tu ncua raws li kev tswj qhov kub thiab txias.
2. Cov txheej txheem ua kua dej - siv cov tshuab txhaj tshuaj molding, cov khoom siv slurry yog txhaj rau hauv pwm zoo li chocolate sauce, thiab los ntawm kev tswj xyuas meej ntawm cov dej ntws, cov qauv hollow complex yog zoo li tus. Txoj kev no ua rau nws muaj peev xwm tsim cov nozzles tsis tu ncua rau satellite thrusters.
3. hmoov reconstruction technology – siv hmoov metallurgy technology los reconstruct lub microstructure ntawm cov ntaub ntawv zoo li lub tsev blocks, tsim nuclear reactor seals uas muab lub zog thiab precision. Cov txheej txheem no tso cai rau cov ntaub ntawv mus rau "kev hloov pauv" ntawm qib molecular, ua tiav cov phiaj xwm kev txhim kho hauv kev ua haujlwm.
Cov ntsiab lus tseem ceeb ntawm precision machining
Yuav kom paub cov khoom siv no, tsis yog tsuas yog cov cuab yeej siv siab heev, tab sis kuj yuav tsum tau muab peb txoj cai golden: tus qauv tsim pwm, kev soj ntsuam xyuas cov txheej txheem nruj, thiab cov khoom siv nruj heev. Shandong Zhongpeng nruj me ntsis raws li peb txoj cai nyob rau hauv cov txheej txheem ntau lawm, sib zog ua kom zoo thiab kom muaj nuj nqis. Nws tsis tsuas yog yuav tsum tau nce hauv cov khoom tiav lawm, tab sis kuj xav kom cov khoom tiav nruj me ntsis raws li cov neeg siv khoom xav tau.
Tam sim no, nrog rau kev siv cov thev naus laus zis tshiab xws li kev ua laser thiab ultrasonic pab txiav, silicon carbide ceramics tau tawg los ntawm kev ua haujlwm kawg. Cov kev tawg no tsis tsuas yog tso cai rau "dub gemstones" tiag tiag txav mus rau kev lag luam, tab sis kuj qhia txog kev tuaj txog ntawm cov khoom hloov pauv tshiab.
Rau cov tuam txhab tsim khoom nrhiav kev ua haujlwm thev naus laus zis, kev ua silicon carbide yog ob qho kev sib tw thiab lub sijhawm. Xaiv cov koom tes ua haujlwm nrog kev paub nplua nuj thiab cov txheej txheem tshiab yuav dhau los ua tus yuam sij kub qhib qhov rooj rau kev tsim khoom siab. Cov ntaub ntawv no, ib zaug suav hais tias yog 'txhim kho lub raj mis', tab tom tos rau ntau tus phab ej los nthuav tawm nws qhov kev paub tsis meej kawg.
