Properties Thiab Advantages Of Cubic Boron Nitride Films
Aug 25, 2023
Cubic Boron Nitride (cBN)yog ib qho khoom siv siab heev uas tsis ntev los no tau txais kev saib xyuas thoob plaws hauv thaj chaw ntawm txheej txheej. Nws yog ib qho allotrope ntawm boron nitride, uas muaj cov qauv zoo li pob zeb diamond thiab nthuav tawm cov khoom tshwj xeeb.
cBN films yog ib qho nyuaj heev thiab ruaj khov, nrog rau siab hnav, corrosion, thiab oxidation. Lawv kuj muaj kev ruaj khov ntawm qhov kub thiab txias thiab muaj cov thermal conductivity zoo, ua rau lawv cov ntaub ntawv zoo tshaj plaws rau kev tiv thaiv hauv ib puag ncig hnyav.
cBN films muaj ntau yam zoo dua lwm cov txheej tiv thaiv. Lawv tuaj yeem muab tso rau ntawm ntau yam substrates, suav nrog hlau, ceramic, thiab semiconductor cov ntaub ntawv, thiab nthuav tawm cov khoom adhesion zoo heev. Ntxiv mus, cov yeeb yaj kiab no yog pob tshab heev, ua rau lawv siv tau rau hauv kev siv kho qhov muag xws li qhov rais thiab lo ntsiab muag.
Daim ntawv thov ntawm cBN films yog tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li aerospace, txiav cov cuab yeej, thiab microelectronics. Nyob rau hauv aerospace, cBN films yog siv los tiv thaiv lub cav Cheebtsam ntawm hnav thiab corrosion los ntawm kev txo cov kev sib txhuam thiab nce hardness. Hauv cov cuab yeej txiav, cBN zaj duab xis yog siv los txhim kho qhov hnav tsis kam thiab txuas ntxiv lub neej ntawm cov cuab yeej. Hauv microelectronics, cBN cov yeeb yaj kiab tau siv los ua cov txheej txheem tiv thaiv los txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov khoom siv hluav taws xob.
Zuag qhia tag nrho, cBN cov yeeb yaj kiab muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg thiab muaj ntau yam txiaj ntsig thoob plaws ntau yam kev lag luam. Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv siab, cBN films tau dhau los ua cov khoom siv tseem ceeb rau kev txhim kho kev ua tau zoo thiab ua haujlwm ntev ntawm cov khoom siv tseem ceeb thiab cov khoom siv.
