Ukusetyenziswa kunye neempawu ze-silicon carbide CVD coating

I-Silicon carbide (i-SiC) luhlobo lwemathiriyeli ye-ceramic enokusetyenziswa okubanzi, ene-conductivity egqwesileyo ye-thermal, ukuzinza kweekhemikhali kunye nokumelana nokushisa okuphezulu.Ukuze kuphuculwe ngakumbi ukusebenza kunye noluhlu lwesicelo se-silicon carbide, iteknoloji ye-chemical vapor deposition (CVD) ibe yindlela ebalulekileyo yokulungisa i-silicon carbide coating.

I-silicon carbide ye-CVD yokugquma ingenza iyunifomu kunye nomgangatho okhuselweyo okhuselweyo kwii-substrates ezahlukeneyo, kwaye ineendawo ezahlukeneyo eziphezulu.Okokuqala, i-silicon carbide coating inobunzima obuphezulu kakhulu kunye nokumelana nokunxiba, okunokuthi kuxhathise ngokufanelekileyo ukunxiba kunye nokukrwela kunye nokukhusela i-substrate ekunxibeni nasekudlekeni.Okwesibini, i-silicon carbide coating inokumelana nobushushu obuphezulu kwaye isenokugcina amandla omatshini aphezulu kunye nokuzinza kweekhemikhali phantsi kobushushu obuphezulu.Oku kwenza i-silicon carbide CVD i-coating isetyenziswe ngokubanzi kwi-aerospace, amandla, iikhemikhali kunye nezinye iindawo, ezifana negumbi lokutshisa elingaphakathi eludongeni, izinzwa zegesi eziphezulu kunye nezixhobo zombane zobushushu obuphezulu.

Ukongeza, i-silicon carbide coating nayo ine-conductivity egqwesileyo ye-thermal kunye neempawu zokufakelwa kombane.I-Thermal conductivity ibhekisa kumandla wesixhobo sokuqhuba ubushushu, kunye ne-thermal conductivity ephezulu ye-silicon carbide CVD coatings izenza zilungele usetyenziso lolawulo lobushushu, njengeeradiyetha kunye nemibhobho yobushushu.Ukugquma kombane kubhekiselele ekusebenzeni kokugquma kwemathiriyeli kungokunje, kunye nokugquma kombane okulungileyo kwesilicon carbide coating kuyenza isetyenziswe ngokubanzi kwizixhobo zombane, ezinje ngomgangatho ophezulu wokugquma ombane kunye nokupakishwa kwe-elektroniki.

Xa ulungiselela i-silicon carbide CVD coatings, iigesi ze-precursor eziqhelekileyo ziquka imithombo ye-silicon kunye nemithombo yekhabhoni efana ne-methane kunye ne-silane.Ezi gesi zenza umaleko obhityileyo we-silicon carbide kumphezulu we-substrate ngokusabela kwe-CVD.Ngokulungelelanisa iimeko zokusabela, ezifana nobushushu, uxinzelelo lomoya kunye nokuhamba kwegesi, ubukhulu, i-morphology kunye neempawu zokugqoka zingalawulwa.

Isishwankathelo, i-silicon carbide ye-CVD yokugquma inenani leempawu eziphezulu, kubandakanywa ubunzima obuphezulu, ukuxhathisa ukunxiba, ukumelana nobushushu obuphezulu, ukuhanjiswa kwe-thermal kunye nokufakelwa kombane.Ezi zakhiwo zenza iingubo ze-silicon carbide zibe noluhlu olubanzi lwezicelo kwiinkalo ezininzi, kubandakanywa i-aerospace, amandla, iikhemikhali kunye ne-electronics.Ngophuhliso oluqhubekayo kunye nokuphuculwa kweteknoloji ye-CVD, ukusebenza kwe-silicon carbide coating kuya kuphuculwa ngakumbi, ukubonelela ngamathuba amaninzi kwizicelo ezininzi kwiinkalo ezininzi.
