Molybdenum Hlau Hom thiab Daim Ntawv Thov

Cov khoom siv CPC (tooj liab / molybdenum tooj liab / tooj liab cov khoom siv sib xyaw) - cov khoom siv zoo tshaj plaws rau cov pob zeb ceramic

Cu Mo Cu/ Copper Composite Material (CPC) yog cov khoom siv zoo tshaj plaws rau lub hauv paus pob zeb ceramic, nrog cov thermal conductivity, qhov ruaj khov, lub zog txhua yam, tshuaj lom neeg ruaj khov thiab kev ua haujlwm rwb thaiv tsev. Nws tsim tau thermal expansion coefficient thiab thermal conductivity ua rau nws zoo tagnrho ntim khoom rau RF, microwave thiab semiconductor high-power li.

Zoo ib yam li tooj liab / molybdenum / tooj liab (CMC), tooj liab / molybdenum-tooj ​​liab / tooj liab kuj yog cov qauv sandwich. Nws yog tsim los ntawm ob txheej txheej-tooj ​​liab (Cu) qhwv nrog cov tub ntxhais txheej-molybdenum tooj liab alloy (MoCu). Nws muaj qhov sib txawv thermal expansion coefficients hauv cheeb tsam X thiab Y cheeb tsam. Piv nrog rau tungsten tooj liab, molybdenum tooj liab thiab tooj liab / molybdenum / tooj liab cov ntaub ntawv, tooj liab-molybdenum-tooj ​​liab-tooj ​​liab (Cu / MoCu / Cu) muaj thermal conductivity ntau dua thiab tus nqi kuj zoo.

Cov khoom siv CPC (tooj liab / molybdenum tooj liab / tooj liab cov khoom siv sib xyaw) - cov khoom siv zoo tshaj plaws rau cov pob zeb ceramic

CPC cov khoom siv yog tooj liab / molybdenum tooj liab / tooj liab hlau cov khoom siv nrog cov yam ntxwv ua haujlwm hauv qab no:

1. Cov thermal conductivity ntau dua li CMC

2. tuaj yeem xuas nrig ntaus rau hauv qhov chaw kom txo tau cov nqi

3. Kev sib txuas ruaj khov, tuaj yeem tiv taus 850℃kub kub cuam tshuam ntau zaus

4. Designable thermal expansion coefficient, txuam cov ntaub ntawv xws li semiconductors thiab ceramics

5. Tsis muaj hlau nplaum

Thaum xaiv cov khoom ntim rau cov pob zeb ceramic pob, cov hauv qab no feem ntau yuav tsum tau xav txog:

Thermal conductivity: Cov pob zeb ceramic pob hauv paus yuav tsum muaj cov thermal conductivity zoo kom ua kom cov cua sov zoo thiab tiv thaiv cov khoom ntim los ntawm kev puas tsuaj los ntawm overheating. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv CPC cov ntaub ntawv uas muaj thermal conductivity ntau dua.

Dimensional stability: Cov khoom siv hauv pob yuav tsum muaj qhov zoo ntawm qhov ruaj khov los xyuas kom meej tias cov khoom ntim tuaj yeem tswj tau qhov loj me nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, thiab zam lub pob tsis ua haujlwm vim cov khoom nthuav tawm lossis kev cog lus.

Mechanical Strength: CPC cov ntaub ntawv yuav tsum muaj cov cuab yeej muaj zog txaus los tiv thaiv kev ntxhov siab thiab kev cuam tshuam sab nraud thaum sib dhos thiab tiv thaiv cov khoom ntim los ntawm kev puas tsuaj.

Chemical Stability: Xaiv cov ntaub ntawv uas muaj cov tshuaj lom neeg ruaj khov, uas tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv ntau yam ib puag ncig thiab tsis corroded los ntawm tshuaj lom neeg.

Rwb thaiv tsev cov khoom: CPC cov ntaub ntawv yuav tsum muaj cov khoom siv rwb thaiv tsev zoo los tiv thaiv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob los ntawm hluav taws xob tsis ua hauj lwm thiab kev tawg.

CPC siab thermal conductivity hluav taws xob ntim khoom

CPC ntim cov ntaub ntawv tuaj yeem muab faib ua CPC141, CPC111 thiab CPC232 raws li lawv cov khoom siv. Cov lej tom qab lawv feem ntau txhais tau tias qhov kev faib ua feem ntawm cov khoom siv ntawm cov qauv sandwich.
