Yintoni i-silicon carbide coating?

Ukufakwa kwe-silicon carbide,eyaziwa ngokuba yi-SiC coating, ibhekisa kwinkqubo yokufaka umaleko wesilicon carbide kumphezulu ngokusebenzisa iindlela ezifana neChemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), okanye ukutshiza nge-thermal. Le silicon carbide yokugquma ngeceramic yongeza iipropathi zomphezulu we-substrates ezahlukeneyo ngokunika ukuxhathisa okungaqhelekanga, ukuzinza kwe-thermal, kunye nokukhuselwa komhlwa. I-SiC yaziwa ngeempawu zayo ezibalaseleyo zomzimba kunye neekhemikhali, kubandakanywa indawo ephezulu yokunyibilika (malunga ne-2700 ℃), ukuqina okugqithisileyo (i-Mohs isikali se-9), ukugqwesa okugqwesileyo kunye nokumelana ne-oxidation, kunye nokusebenza okukhethekileyo kokukhupha.

Izibonelelo eziphambili zeSilicon Carbide Coating kwi-Industrial Applications

Ngenxa yezi mpawu, i-silicon carbide coating isetyenziswa ngokubanzi kumacandelo anje nge-aerospace, izixhobo zezixhobo, kunye nokusetyenzwa kwe-semiconductor. Kwiimeko ezingqongileyo ezigqithisileyo, ngakumbi phakathi koluhlu lwe-1800-2000 ℃, ukugquma kwe-SiC kubonisa ukuzinza okumangalisayo kwe-thermal kunye nokumelana nokushisa, okwenza kube yinto efanelekileyo kwizicelo zokushisa okuphezulu. Nangona kunjalo, i-silicon carbide iyodwa ayinayo imfezeko yolwakhiwo olufunekayo kwizicelo ezininzi, ngoko ke iindlela zokugquma ziyasetyenziswa ukuze kunyuswe iipropathi zayo ezizodwa ngaphandle kokuthomalalisa amandla ecandelo. Kwimveliso ye-semiconductor, izinto ezifakwe kwi-silicon carbide zibonelela ngokhuseleko oluthembekileyo kunye nokuzinza kokusebenza ngaphakathi kwezixhobo ezisetyenziswa kwiinkqubo ze-MOCVD.

Iindlela eziqhelekileyo zokuLungisa i-Silicon Carbide Coating

Ⅰ● I-Chemical Vapor Deposition (CVD) i-Silicon Carbide Coating

Kule ndlela, iingubo ze-SiC zenziwe ngokubeka i-substrates kwigumbi lokuphendula, apho i-methyltrichlorosilane (MTS) isebenza njenge-precursor. Ngaphantsi kweemeko ezilawulwayo-ngokuqhelekileyo i-950-1300 ° C kunye noxinzelelo olubi-i-MTS idlula ukubola, kwaye i-silicon carbide ifakwe phezu komhlaba. Le nkqubo yokwaleka ye-CVD SiC iqinisekisa ukuxinana, ukugquma okufanayo kunye nokubambelela okugqwesileyo, ilungele usetyenziso oluchanekileyo kumacandelo e-semiconductor kunye ne-aerospace.

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

Enye indlela esebenzayo yokugquma isitshizi se-silicon carbide yindlela yokuguqula i-precursor, ebandakanya ukuntywiliselwa isampulu enyangwe ngaphambili kwisisombululo se-ceramic precursor. Emva kokucoca itanki yokungena kunye nokucinezela isambatho, isampuli iyafudunyezwa, ikhokelela kukwakheka kwe-silicon carbide xa ipholisa. Le ndlela ithandwa kumacandelo afuna ubukhulu obufanayo bokugquma kunye nokuqina kokumelana nokunxiba.

IiPropati zoMzimba zeSilicon Carbide Coating

Iingubo ze-silicon ze-carbide zibonisa iipropathi ezenza zibe zilungele ukufunwa kwezicelo zemizi-mveliso. Ezi propati ziquka:

I-Thermal Conductivity: 120-270 W/m·K
I-Coefficient yoKwandiswa kwe-Thermal: 4.3 × 10 ^^(-6)/K (ku-20~800℃)
Ukuxhathisa koMbane: 10^⁵– 10^⁶Ω·cm
Ubunzima: Mohs isikali 9

Ukusetyenziswa kweSilicon Carbide Coating

Kwimveliso ye-semiconductor, i-silicon carbide coating ye-MOCVD kunye nezinye iinkqubo eziphezulu zokushisa zikhusela izixhobo ezibalulekileyo, ezifana ne-reactors kunye ne-susceptors, ngokunikezela zombini ukuchasana nokushisa okuphezulu kunye nokuzinza. Kwi-aerospace kunye nokukhusela, i-silicon carbide i-ceramic coatings isetyenziswe kumacandelo ekufuneka amelane neempembelelo zesantya esiphezulu kunye neendawo ezinobungozi. Ngaphaya koko, ipeyinti ye-silicon carbide okanye i-coatings inokusetyenziswa kwizixhobo zonyango ezifuna ukuqina phantsi kweenkqubo zokuvala inzala.

Kutheni ukhetha iSilicon Carbide Coating?

Ngerekhodi eqinisekisiweyo ekwandiseni ubomi becandelo, iingubo ze-silicon carbide zibonelela ngokuzinzileyo kunye nokuzinza kweqondo lokushisa, okwenza kube yindleko-esebenzayo ekusebenziseni ixesha elide. Ngokukhetha indawo egqunywe ngesilicon carbide, amashishini axhamla kwiindleko zokunciphisa ukugcinwa, ukuthembeka kwezixhobo eziphuculweyo, kunye nokuphucula ukusebenza kakuhle.
