Yintoni i-silicon carbide coating?

Ukwambathisa i-silicon carbide,eyaziwa ngokuba yi-SiC coating, ibhekisa kwinkqubo yokufaka umaleko we-silicon carbide kwiindawo ngokusebenzisa iindlela ezifana ne-Chemical Vapor Deposition (CVD), i-Physical Vapor Deposition (PVD), okanye i-thermal spray. Le silicon carbide ceramic coating iphucula iipropati zomphezulu we-substrates ezahlukeneyo ngokubonelela ngokumelana nokuguguleka okugqwesileyo, uzinzo lobushushu, kunye nokukhuselwa kokugqwala. I-SiC yaziwa ngeempawu zayo zomzimba nezekhemikhali ezibalaseleyo, kubandakanya indawo yokunyibilika ephezulu (malunga ne-2700℃), ubunzima obukhulu (isikali se-Mohs 9), ukumelana nokugqwala kunye ne-oxidation okugqwesileyo, kunye nokusebenza okugqwesileyo kwe-ablation.

Iingenelo eziphambili zeSilicon Carbide Coating kwizicelo zemizi-mveliso

Ngenxa yezi mpawu, i-silicon carbide coating isetyenziswa kakhulu kwiindawo ezifana ne-aerospace, izixhobo zezixhobo, kunye nokucubungula i-semiconductor. Kwiindawo ezishushu kakhulu, ngakumbi ngaphakathi koluhlu lwe-1800-2000℃, i-SiC coating ibonisa uzinzo olumangalisayo lobushushu kunye nokumelana nokutsha, okwenza ukuba ilungele ukusetyenziswa kumaqondo obushushu aphezulu. Nangona kunjalo, i-silicon carbide yodwa ayinalo ulungelelwaniso lwesakhiwo olufunekayo kwizicelo ezininzi, ngoko ke iindlela zokugquma zisetyenziswa ukuze zisebenzise iipropati zayo ezikhethekileyo ngaphandle kokuphazamisa amandla ecandelo. Kwimveliso ye-semiconductor, izinto ezigqunywe yi-silicon carbide zibonelela ngokhuseleko oluthembekileyo kunye nokuzinza kokusebenza ngaphakathi kwezixhobo ezisetyenziswa kwiinkqubo ze-MOCVD.

Iindlela eziqhelekileyo zokulungiselela iSilicon Carbide Coating

Ⅰ● Ukufakwa koMphunga weKhemikhali (i-CVD) iSilicon Carbide Coating

Kule ndlela, ii-coating ze-SiC zenziwa ngokubeka ii-substrates kwigumbi lokusabela, apho i-methyltrichlorosilane (MTS) isebenza njenge-precursor. Phantsi kweemeko ezilawulwayo—ngesiqhelo i-950-1300°C kunye noxinzelelo olubi—i-MTS iyabola, kwaye i-silicon carbide ifakwa kumphezulu. Le nkqubo yokugquma ye-CVD SiC iqinisekisa i-coating exineneyo, efanayo enamathele kakuhle, efanelekileyo kwizicelo ezichanekileyo kakhulu kwicandelo le-semiconductor kunye ne-aerospace.

Ⅱ● Indlela yokuguqula i-Precursor (i-Polymer Impregnation kunye ne-Pyrolysis – PIP)

Enye indlela esebenzayo yokugquma i-silicon carbide yindlela yokuguqula i-precursor, equka ukuntywilisela isampuli esele ilungisiwe kwisisombululo se-ceramic precursor. Emva kokucoca itanki yokufunxa kunye nokufaka uxinzelelo kwi-coating, isampuli iyafudunyezwa, nto leyo ekhokelela ekwakhekeni kwe-silicon carbide coating xa ipholile. Le ndlela ithandwa kakhulu kwiindawo ezifuna ubukhulu obufanayo be-coating kunye nokumelana nokuguguleka okuphuculweyo.

Iipropati Zomzimba ZeSilicon Carbide Coating

Iingubo ze-silicon carbide zibonisa iimpawu ezenza ukuba zilungele ukusetyenziswa kwemizi-mveliso enzima. Ezi mpawu ziquka:

Ukuqhuba kwe-Thermal: 120-270 W/m·K
I-Coefficient yoKwandiswa koBushushu: 4.3 × 10^^(-6)/K (kwi-20~800℃)
Ukumelana nombane: 10^⁵– 10^⁶Ω·cm
Ubunzima: Isikali se-Mohs 9

Ukusetyenziswa kweSilicon Carbide Coating

Kwimveliso ye-semiconductor, i-silicon carbide coating ye-MOCVD kunye nezinye iinkqubo zobushushu obuphezulu ikhusela izixhobo ezibalulekileyo, ezinje ngee-reactors kunye nee-susceptors, ngokubonelela ngokumelana nokuqina kobushushu obuphezulu. Kwi-aerospace kunye nokuzikhusela, i-silicon carbide ceramic coatings isetyenziswa kwizinto ezimele zimelane nefuthe lesantya esiphezulu kunye neendawo ezirhabaxa. Ngaphezu koko, ipeyinti okanye i-silicon carbide coatings ingasetyenziswa nakwizixhobo zonyango ezifuna ukuqina phantsi kweenkqubo zokubulala iintsholongwane.

Kutheni Ukhetha iSilicon Carbide Coating?

Njengoko inerekhodi eqinisekisiweyo yokwandisa ubomi bezinto, ii-silicon carbide coatings zibonelela ngokuqina okungenakuthelekiswa nanto kunye nokuzinza kobushushu, nto leyo eyenza ukuba zisebenziseke kakuhle ixesha elide. Ngokukhetha umphezulu ogqunywe yi-silicon carbide, amashishini azuza kwiindleko zokugcinwa eziphantsi, ukuthembeka kwezixhobo okuphuculweyo, kunye nokusebenza kakuhle okuphuculweyo.
