Kugwiritsa ntchito CVD SiC Coating
TheChophimba cha CVD SiCNjirayi imagwiritsidwa ntchito kwambiri m'mafakitale angapo chifukwa cha kusinthasintha kwake komanso ubwino wake. Chimodzi mwa ntchito zazikulu ndi kupanga zinthu za semiconductor, komwe zida zophimbidwa ndi SiC zimathandiza kuteteza malo ofooka panthawi yokonza wafer. Zipangizo zophimbidwa ndi CVD SiC, monga ma susceptors, mphete, ndi zonyamulira za wafer, zimathandizira kukhazikika kwa kutentha kwambiri ndikuletsa kuipitsidwa panthawi yofunika kwambiri yopanga.
Mu makampani opanga ndege,Chophimba cha CVD SiCimagwiritsidwa ntchito pazinthu zomwe zimakhudzidwa ndi kutentha kwambiri komanso kupsinjika kwa makina. Chophimbachi chimakulitsa kwambiri moyo wa masamba a turbine ndi zipinda zoyaka moto, zomwe zimagwira ntchito pansi pa mikhalidwe yovuta. Kuphatikiza apo, CVD SiC imagwiritsidwa ntchito kwambiri popanga magalasi ndi zida zowunikira chifukwa cha mphamvu zake zowunikira komanso kukhazikika kwa kutentha.
Ntchito ina yofunika kwambiri ya CVD SiC ndi mumakampani opanga mankhwala. Apa, zophimba za SiC zimateteza zinthu monga zosinthira kutentha, zomatira, ndi mapampu ku zinthu zowononga. Pamwamba pa SiC sipakhudzidwa ndi ma acid ndi maziko, zomwe zimapangitsa kuti ikhale yoyenera malo omwe kulimba kwa mankhwala ndikofunikira.
Makhalidwe a CVD SiC Coating
Kapangidwe ka CVD SiC coverage ndi komwe kamapangitsa kuti ikhale yothandiza kwambiri pa ntchito izi. Chimodzi mwa makhalidwe ake akuluakulu ndi kuuma kwake, komwe kuli pafupi ndi diamondi pa sikelo ya Mohs hardness. Kuuma kwakukulu kumeneku kumapangitsa kuti CVD SiC coverage ikhale yolimba kwambiri kuti isawonongeke komanso kuti isawonongeke, zomwe zimapangitsa kuti ikhale yoyenera malo omwe amakangana kwambiri.
Kuphatikiza apo, SiC ili ndi kutentha kwabwino kwambiri, komwe kumalola zigawo zophimbidwa kuti zisunge umphumphu wawo ngakhale kutentha kwambiri. Izi ndizofunikira kwambiri pakugwiritsa ntchito ma semiconductor ndi aerospace, komwe zipangizo ziyenera kupirira kutentha kwambiri komanso kusunga mphamvu ya kapangidwe kake.
Kusagwira ntchito kwa mankhwala a CVD SiC coverage ndi ubwino wina wodziwika bwino. Imalimbana ndi okosijeni, dzimbiri, ndi kusintha kwa mankhwala ndi zinthu zamphamvu, zomwe zimapangitsa kuti ikhale cover yabwino kwambiri pazida zopangira mankhwala. Kuphatikiza apo, kuchuluka kwake kochepa kwa kutentha kumathandizira kuti malo ophimbidwa azisunga mawonekedwe awo ndikugwira ntchito ngakhale kutentha kutakhala kotentha kwambiri.
Mapeto
Mwachidule, chophimba cha CVD SiC chimapereka yankho lolimba komanso logwira ntchito bwino kwambiri m'mafakitale omwe amafunikira zinthu zomwe zimatha kupirira kutentha kwambiri, kupsinjika kwa makina, komanso dzimbiri la mankhwala. Ntchito zake zimayambira pakupanga zinthu za semiconductor mpaka kukonza ndege ndi mankhwala, komwe makhalidwe a SiC—monga kuuma, kukhazikika kwa kutentha, komanso kukana mankhwala—ndi ofunikira kwambiri kuti ntchito iyende bwino. Pamene mafakitale akupitilizabe kupititsa patsogolo magwiridwe antchito ndi kudalirika, chophimba cha CVD SiC chidzakhalabe ukadaulo wofunikira pakulimbikitsa kulimba kwa zigawo ndi moyo wautali.
Pogwiritsa ntchito ukatswiri wa opanga apadera monga vet-china, makampani amatha kupeza zokutira za CVD SiC zapamwamba zomwe zimakwaniritsa zofunikira zamakampani amakono.
