Kugwiritsa ntchito ndi mawonekedwe a silicon carbide CVD zokutira

Silicon carbide (SiC)ndi chinthu cholimba kwambiri chomwe chimadziwika chifukwa cha kuuma kwake kwapamwamba, kutsekemera kwapamwamba kwambiri, komanso kukana kuwonongeka kwa mankhwala. Mwa njira zosiyanasiyana zogwiritsira ntchito SiC pamwamba,CVD SiC zokutira(Chemical Vapor Deposition of silicon carbide) imadziwika chifukwa cha kuthekera kwake kupanga zokutira zofananira, zoyera kwambiri zomatira bwino kwambiri. Tekinoloje iyi ndiyofunikira pazantchito zosiyanasiyana zamafakitale, makamaka m'malo otentha kwambiri komanso m'malo owopsa amankhwala.

Kugwiritsa ntchito CVD SiC Coating

TheCVD SiC zokutiraNjirayi imagwiritsidwa ntchito kwambiri m'mafakitale angapo chifukwa cha kusinthasintha kwake komanso magwiridwe antchito. Chimodzi mwazofunikira kwambiri ndikupanga semiconductor, pomwe zida zokutidwa ndi SiC zimathandizira kuteteza malo osalimba panthawi yokonza zophika. Zida zophimbidwa ndi CVD SiC, monga susceptors, mphete, ndi zonyamulira zowotcha, zimatsimikizira kukhazikika kwa kutentha kwapamwamba komanso kuteteza kuipitsidwa panthawi yovuta kwambiri yopangira.

M'makampani azamlengalenga,CVD SiC zokutiraamagwiritsidwa ntchito pazigawo zomwe zimakhudzidwa ndi kutentha kwakukulu ndi kupanikizika kwa makina. Chophimbacho chimakulitsa kwambiri moyo wa masamba a turbine ndi zipinda zoyaka, zomwe zimagwira ntchito movutikira. Kuphatikiza apo, CVD SiC imagwiritsidwa ntchito kwambiri popanga magalasi ndi zida zamagetsi chifukwa cha mawonekedwe ake owoneka bwino komanso okhazikika.

Ntchito ina yofunika kwambiri ya CVD SiC ili m'makampani opanga mankhwala. Apa, zokutira za SiC zimateteza zinthu monga zosinthira kutentha, zisindikizo, ndi mapampu kuzinthu zowononga. SiC pamwamba imakhalabe yosakhudzidwa ndi ma acid ndi maziko, ndikupangitsa kuti ikhale yabwino kwa malo omwe kukhazikika kwa mankhwala ndikofunikira.

Makhalidwe a CVD SiC Coating

Zovala za CVD SiC zokutira ndizomwe zimapangitsa kuti zikhale zogwira mtima pamapulogalamuwa. Chimodzi mwazofunikira zake ndikulimba kwake, kuyika pafupi ndi diamondi pamlingo wa Mohs hardness. Kuuma kwambiri kumeneku kumapereka zokutira za CVD SiC kukana kodabwitsa kuti zisavalidwe ndi ma abrasion, zomwe zimawapangitsa kukhala oyenera malo akukangana kwambiri.

Kuphatikiza apo, SiC ili ndi matenthedwe abwino kwambiri, omwe amalola kuti zida zokutira zisunge umphumphu ngakhale kutentha kwambiri. Izi ndizofunikira makamaka pamapangidwe a semiconductor ndi zamlengalenga, pomwe zida ziyenera kupirira kutentha kwambiri ndikusunga mphamvu zamapangidwe.

Kusakhazikika kwamankhwala kwa CVD SiC zokutira ndi mwayi wina wodziwika. Imakana makutidwe ndi okosijeni, dzimbiri, komanso kukhudzidwa kwamankhwala ndi zinthu zaukali, kupangitsa kuti ikhale yopaka bwino pazida zopangira mankhwala. Kuphatikiza apo, mphamvu yake yocheperako pakukulitsa kwamafuta imatsimikizira kuti malo ophimbidwa amakhalabe ndi mawonekedwe awo ndikugwira ntchito ngakhale pansi pa kutentha kwa njinga.

Mapeto

Mwachidule, zokutira za CVD SiC zimapereka njira yokhazikika, yogwira ntchito kwambiri m'mafakitale omwe amafunikira zida zomwe zimatha kupirira kutentha kwambiri, kupsinjika kwamakina, ndi dzimbiri lamankhwala. Ntchito zake zimachokera ku kupanga semiconductor kupita kumlengalenga ndi kukonza mankhwala, komwe katundu wa SiC-monga kuuma, kukhazikika kwa kutentha, ndi kukana kwa mankhwala-ndizofunika kwambiri kuti ntchito ikhale yopambana. Pamene mafakitale akupitiliza kukankhira malire a magwiridwe antchito ndi kudalirika, zokutira za CVD SiC zidzakhalabe ukadaulo wofunikira pakupititsa patsogolo kulimba kwa gawo ndi moyo wautali.

Pogwiritsa ntchito ukadaulo wa opanga apadera ngati vet-china, makampani amatha kupeza zokutira zapamwamba za CVD SiC zomwe zimakwaniritsa zofunikira zamabizinesi amakono.
