CVD TaC txheej

 

Taw qhia rau CVD TaC Txheej:

 

CVD TaC Txheej yog ib qho cuab yeej siv tshuaj vapor deposition los tso tantalum carbide (TaC) txheej rau saum npoo ntawm substrate. Tantalum carbide yog cov khoom siv ua haujlwm siab ceramic nrog cov khoom siv zoo heev thiab tshuaj lom neeg. Cov txheej txheem CVD tsim cov yeeb yaj kiab TaC tsis sib xws ntawm qhov chaw ntawm lub substrate los ntawm cov tshuaj tiv thaiv roj.

 

Cov yam ntxwv tseem ceeb:

 

Zoo heev hardness thiab hnav tsis kam: Tantalum carbide muaj qhov nyuaj siab heev, thiab CVD TaC Txheej tuaj yeem txhim kho qhov hnav tsis kam ntawm lub substrate. Qhov no ua rau cov txheej txheem zoo tagnrho rau kev siv hauv qhov chaw hnav khaub ncaws siab, xws li cov cuab yeej txiav thiab pwm.

Kub kub ruaj khov: TaC coatings tiv thaiv lub cub tawg tseem ceeb thiab cov khoom siv reactor ntawm qhov kub txog li 2200 ° C, ua kom pom kev ruaj ntseg zoo. Nws tuav cov tshuaj thiab cov neeg kho tshuab ruaj khov nyob rau hauv qhov kub thiab txias, ua rau nws tsim nyog rau kev ua haujlwm kub thiab siv rau hauv qhov chaw kub kub.

Zoo heev tshuaj stability: Tantalum carbide muaj zog tiv thaiv corrosion rau feem ntau cov kua qaub thiab alkalis, thiab CVD TaC txheej tuaj yeem tiv thaiv kev puas tsuaj rau cov substrate hauv corrosive ib puag ncig.

Siab melting point: Tantalum carbide muaj qhov siab melting point (kwv yees li 3880 ° C), tso cai rau CVD TaC Txheej siv rau hauv qhov kub thiab txias yam tsis muaj melting lossis degrading.

Zoo heev thermal conductivity: TaC txheej muaj cov thermal conductivity siab, uas yuav pab kom zoo dissipate tshav kub nyob rau hauv high-temperature txheej txheem thiab tiv thaiv lub zos overheating.
