Cov khoom siv thiab tawg qhov tob ntawm silicon qws cuam cuam tshuam rau kev kho kub nyhuv kub?

Cov khoom siv thiab tawg qhov tob ntawm silicon cov pas nrig yuav cuam tshuam cov kev kho mob ntawm cov dej kub siab tiv thaiv hauv cov hauv qab no:
Khoom
Kev sib xyaw ua ke: Silicon cov pas nrig Carbon ntau yog ua los ntawm cov chaw tsim khoom lag luam uas tau ua los ntawm cov khoom sib txawv ntawm cov pob zeb ua kom sib txawv Lub siab-dawb huv silicon carbide substrate muaj zoo dua rau nws cov npoo av los tiv thaiv cov pa roj caricon Silicon carbon rods muaj ntau impurities lossis additives yuav hnov ​​cov txheej txheem nrog cov nplaum thiab tiv thaiv cov khoom ntawm txheej.
Cov yam ntxwv saum npoo: Qhov saum npoo roughness, porosity thiab lwm yam ntawm silicon carbon qws kuj tseem yuav cuam tshuam rau kev kho cov nyhuv. Silicon carbon pa pas nrig nrog cov khoom siv ntxhib thiab kev nkag mus rau qhov chaw sib ze thiab cov kab nrib pleb, tuaj yeem txhim kho lub zog, tuaj yeem txhim kho lub zog thiab ua kom muaj zog ntxiv, thiab yog li txhim kho cov nyhuv kho. Yog hais tias saum npoo ntawm silicon carbon qws yog heev du, txheej txheej nplaum tsis txaus; Yog tias cov nplaim hluav taws xob dhau los yog qhov khav tau ntau dhau lawm, nws yuav ua rau muaj kev nkag mus ntau dhau ntawm cov txheej sib txawv, cuam tshuam rau cov khaub ncaws sib txawv thiab kev ncaj ncees ntawm txheej.
Qeeb qhov tob
Kev tso tawm qhov nyuaj: ntiav cov kab nrib pleb yog qhov yooj yim yuav tsum tau sau nrog cov dej sov kub tiv thaiv. Cov txheej tuaj yeem npog cov nplaim tawg thiab nkag mus rau qee yam tob. Tom qab ziab thiab kho tau, nws tuaj yeem tsim zaj duab xis txuas ntxiv, ua tau zoo tiv thaiv kev nthuav dav thiab cov khoom lag luam txawv teb chaws. Txawm li cas los xij, qhov qhib ntawm cov kab nrib pleb tob yog qhov loj thiab sab hauv yog sib sib zog nqus. Nws yog qhov nyuaj rau txheej kom tau ua tiav. Nws yog ib qho yooj yim los ua cov khoob lossis npuas hauv cov kab nrib pleb, uas ua rau muaj kev txo qis hauv cov nyhuv tiv thaiv. Txawm hais tias cov txheej txheej txheej txheej txheej rau saum npoo, yog tias qhov tawg sib sib zog tsis tau ua tiav ntawm kev puas tsuaj ntxiv rau cov pas dej silicon.
Kev ntxhov siab txog kev ntxhov siab: kev ntxhov siab pom kev zoo siab ntawm kev sib nraws tob yog qhov hnyav dua. Thaum lub caij cua sov thiab txias txheej txheem ntawm silicon carbon carbon qws, vim yog thermal expansion thiab meraction, kev ntxhov siab ntau dua yuav tsim nyob ib puag ncig cov kab nrib pleb. Cov kab nrib pleb ntiav muaj tsawg dua kev puas tsuaj rau cov qauv txheej txheem thiab kev ntxhov siab txo qis. Cov txheej tuaj yeem tiv taus qee yam kev ntxhov siab thiab tswj kev ncaj ncees ntawm txheej. Txawm li cas los xij, rau kev sib nraws tob, kev nyuaj siab concentrular tej zaum yuav ua rau muaj kev txwv, ua rau cov khoom siv silicurely, ua rau cov sillicon carbon qws poob kev tiv thaiv thiab nrawm nws puas tsuaj.
Oxidation txoj kev: Cov kab nrib pleb sib sib zog nqus tau ncaj qha thiab tob dua channelen xws li sixyging tshuaj xws li sixibrizing tej yam xws li silicon carbon pev roj ntau dua oxidized. Txawm hais tias saum npoo yog coated nrog high-kub tiv taus txheej, oxygen tseem nyob sab hauv ntawm Silicon Carbon qws los ntawm kev sib nraws sib tsoo thiab ua rau cov tshuaj oxidation. Hauv kev sib piv, txoj kev oxidation ntawm cov kab nrib pleb ntiav yog luv dua, thiab cov txheej txuas ntxiv tau ntau dua cov oxidation, thiab yog li txhim kho cov nyhuv kho mob.
