Lub thermal conductivity ntawm Chromium Carbide txawv ntawm cov khoom siv li cas?

Chromium carbide yog cov khoom siv kub kub kub uas muaj thermal conductivity zoo heev. Muaj ntau qhov sib txawv tseem ceeb hauv thermal conductivity ntawm chromium carbide piv rau cov khoom siv sib xyaw.

Ua ntej, chromium carbide muaj cov thermal conductivity siab. Thermal conductivity yog lub peev xwm ntawm cov khoom siv los ua kom sov hauv qhov kub thiab txias thiab feem ntau qhia tias thermal conductivity tas li. Chromium carbide muaj cov thermal conductivity siab, uas tuaj yeem siab li 200-250 W/(mK), ob peb zaug siab dua ntau cov khoom siv xws li txhuas thiab tooj liab. Qhov no txhais tau hais tias chromium carbide tuaj yeem ua cua sov sai sai hauv qhov kub thiab txias thiab muaj thermal conductivity zoo dua.

Qhov thib ob, lub thermal conductivity ntawm chromium carbide tsis cuam tshuam los ntawm qhov kub thiab txias. Thaum lub thermal conductivity ntawm cov khoom siv ib txwm txo qis nrog qhov kub thiab txias, chromium carbide tuav lub thermal conductivity txawm tias kub. Qhov no feem ntau yog vim qhov ruaj khov ntawm cov qauv siv lead ua ntawm chromium carbide thiab nws cov thermal conductivity zoo ntawm qhov kub thiab txias. Nyob rau hauv sib piv, cov thermal conductivity ntawm cov pa cov ntaub ntawv tej zaum yuav cuam tshuam los ntawm cov kev hloov nyob rau hauv cov ntaub ntawv qauv thiab thermal expansion ntawm high kub, uas ua rau ib tug txo nyob rau hauv thermal conductivity.

Tsis tas li ntawd, chromium carbide muaj cov thermal conductivity tsawg impedance. Thermal conductivity impedance yog qhov degree uas cov khoom impedes lub conduction ntawm tshav kub, thiab feem ntau yog qhia nyob rau hauv cov nqe lus ntawm coefficient ntawm thermal conductivity. Qhov qis thermal conductivity ntawm chromium carbide qhia tias nws muaj tsawg impedance los ua cua sov. Qhov no txhais tau hais tias chromium carbide tuaj yeem ua kom sov tau zoo dua, nrog tsawg zog poob. Hauv qhov sib piv, cov khoom siv ib txwm muaj cov thermal conductivity ntau dua, ua rau muaj zog ntau dua thaum lub sij hawm conduction.

Tsis tas li ntawd, chromium carbide muaj cov coefficient tsawg ntawm thermal expansion. Lub coefficient ntawm thermal expansion yog qhov uas cov khoom nce nyob rau hauv ntev los yog ntim nyob rau hauv cov lus teb rau ib tug kev hloov nyob rau hauv qhov kub thiab txias, thiab feem ntau yog qhia nyob rau hauv cov nqe lus ntawm μm / (mK) los yog ppm / K. Chromium carbide muaj cov coefficient tsawg ntawm thermal expansion, qhia tias nws nthuav tsawg dua nyob rau hauv qhov kub thiab txias. Qhov no yog ib qho tseem ceeb rau cov khoom siv nyob rau hauv high-temperature ib puag ncig kom txo qis qhov hloov pauv vim thermal expansion thiab txhim kho cov khoom ruaj khov thiab kev ntseeg siab ntawm qhov kub thiab txias. Nyob rau hauv sib piv, cov ntaub ntawv ib txwm muaj ntau dua coefficients ntawm thermal expansion thiab muaj feem xyuam rau qhov seem tsis ruaj khov los yog tawg vim qhov kub thiab txias.

Hauv cov ntsiab lus, piv rau cov khoom siv sib xyaw, chromium carbide muaj cov thermal conductivity siab uas tsis muaj qhov kub thiab txias thiab muaj qhov thermal conductivity impedance thiab coefficient ntawm thermal expansion. Cov khoom no tso cai rau chromium carbide kom muaj thermal conductivity zoo dua thiab ruaj khov nyob rau hauv qhov chaw kub kub rau ntau yam kev siv kub, xws li aerospace, lub zog, thiab hluav taws xob. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv thiab kev ua tiav ntawm chromium carbide thev naus laus zis, nws ntseeg tias nws cov thermal conductivity kev ua tau zoo yuav raug txhim kho ntxiv thiab ua lub luag haujlwm hauv ntau qhov chaw.
