Cov qauv tsim thiab cov txheej txheem sib xyaw ua rau kev ua haujlwm ntawm cov txheej txheem tuaj yeem hloov kho tau, xws li qhov nyuaj, kev tiv thaiv kev hnav thiab kev ruaj khov thermal, ua tau raws li qhov xav tau ntawm ntau yam kev siv.
4. Cov yam ntxwv ntawm cov qauv micro-nano:
Cov khoom me me Nanocomposite ceramic qhwv cov khoom me me hauv micrometer, sau cov qhov sib txawv, tsim cov txheej tuab, thiab txhim kho qhov compactness thiab corrosion tsis kam. Lub caij no, cov nanoparticles nkag mus rau hauv qhov chaw ntawm lub substrate, tsim cov hlau-ceramic interphase, uas txhim kho lub zog sib txuas thiab lub zog tag nrho.
Txoj cai tshawb fawb thiab kev txhim kho
1. Qhov teeb meem sib phim ntawm kev nthuav dav thermal: Cov coefficients ntawm kev nthuav dav thermal ntawm cov hlau thiab cov khoom siv ceramic feem ntau sib txawv thaum lub sijhawm cua sov thiab txias. Qhov no yuav ua rau muaj cov kab nrib pleb me me hauv cov txheej thaum lub sijhawm kub thiab txias, lossis txawm tias tev tawm. Txhawm rau daws qhov teeb meem no, Youcai tau tsim cov ntaub ntawv txheej tshiab uas cov coefficient ntawm kev nthuav dav thermal ze rau ntawm cov hlau substrate, yog li txo cov kev ntxhov siab thermal.
2. Kev tiv thaiv rau kev poob siab thermal thiab kev co thermal: Thaum cov hlau txheej hloov pauv sai ntawm qhov kub siab thiab qis, nws yuav tsum muaj peev xwm tiv taus qhov kev ntxhov siab thermal tsis muaj kev puas tsuaj. Qhov no xav tau cov txheej kom muaj kev tiv thaiv thermal zoo heev. Los ntawm kev ua kom zoo dua cov qauv ntawm cov txheej, xws li kev nce tus lej ntawm cov theem sib txuas thiab txo qhov loj ntawm cov noob, Youcai tuaj yeem txhim kho nws qhov kev tiv thaiv thermal.
3. Lub zog sib txuas: Lub zog sib txuas ntawm cov txheej thiab cov hlau substrate yog qhov tseem ceeb rau kev ruaj khov thiab kev ua haujlwm ntev ntawm cov txheej. Txhawm rau txhim kho lub zog sib txuas, Youcai qhia txog txheej nruab nrab lossis txheej hloov pauv ntawm cov txheej thiab cov substrate kom txhim kho qhov ntub thiab kev sib txuas tshuaj lom neeg ntawm ob qho.
