Wa zonseKufotokozera kwaKuchitaOmangidwa sic

Kuchita Unanda Wokhala ndi makina opanga ndi kukana kwa oxidation. Mtengo wake ndi wotsika. M'mbuyomu, zakhudzanso chidwi cha mafakitale osiyanasiyana.

SIC ndi mgwirizano wamphamvu kwambiri. Polakwira, kusokonekera kwa masitepe kumakhala kochepa kwambiri. Nthawi yomweyo, mawonekedwe a tinthu tating'onoting'ono nthawi zambiri amaphimba malo osanjikiza omwe amatenga gawo la chotchinga. SIC SIC sikachimwa kwambiri komanso yaying'ono popanda zowonjezera zowonjezera. Ngakhale njira yotsatsira kutentha imagwiritsidwa ntchito, iyeneranso kusankha zina zowonjezera. Kokha kutentha kwambiri, kungatheke zida zoyenererana ndi luso lapakati pa kachulukidwe kambiri komwe kuyenera kukhala koyenera kuyambira 1950 ℃ mpaka 2200 ℃. Mawonekedwe ake ndi kukula kwake. Ngakhale ma coossites ophatikizika a SIC akhoza kupezeka ndi VAPOR, amangokhala otsika mtengo kapena zida zowonda. Chifukwa cha nthawi yake yabata yayitali, mtengo wopanga uchuluka.

Mavuto A SIC adapangidwa mu 1950s ndi popper. Mfundo yofunika ndi iyi:

Pansi pa mphamvu ya capillary, silicon yamadzimadzi kapena silika yogwira ntchito yolumikizidwa imalowa m'malo mwamphamvu yopanga zinthu zokhala ndi kaboni ndipo zimapangitsa kuti carbon carbon. Carbide ya Sicon yatsopano imalumikizidwa ndi tinthu tating'ono toyambitsa matenda mu Stuko ku Stuko, ndipo zotsalazo zotsalira mu zosefera zimadzaza ndi ntchito yophatikizira kuti mumalize ntchito.

Poyerekeza ndi njira zina za silicon carbide ma carradics, njira yochimwayo ili ndi izi:

Kutentha kochepa, nthawi yayifupi, sikufunikira zida zapadera kapena zodula;

Machitidwe ophatikizika popanda shrinkage kapena kusintha kwa kukula;

Njira zosungunuka zosinthika (zowonjezera, jakisoni, kukanikiza ndi kuthira).

Pali njira zambiri zokulira. Panthawi ya uchimo, kukula kwakukulu ndi zinthu zovuta zitha kupangidwa popanda kukanikiza. Ukadaulo womwe wagwiridwa ukadaulo wa Silicon Carbide waphunziridwa kwa theka la zaka. Tekinoloje iyi yakhala imodzi mwazomwe zimayang'ana mafakitale osiyanasiyana chifukwa cha zabwino zake zapadera.
