Mphete Yosindikiza ya SiC

Kufotokozera:

Silicon Carbide ili ndi katundu wabwino kwambiri wosamva dzimbiri, mphamvu zamakina apamwamba, matenthedwe apamwamba kwambiri, kudzipaka bwino komwe kumagwiritsidwa ntchito ngati nkhope zosindikizira, machubu ndi machubu mumlengalenga, makina, zitsulo, kusindikiza ndi utoto, zakudya, mankhwala, mafakitale amagalimoto ndi zina zambiri. pa. Pamene nkhope za sic zikuphatikizidwa ndi nkhope za graphite kukangana kumakhala kochepa kwambiri ndipo kungapangidwe kukhala zidindo zamakina zomwe zimatha kugwira ntchito pazofunikira kwambiri.

Silicon Carbide Basic Properties:

-Ochepa kachulukidwe

-High matenthedwe conductivity (pafupi ndi aluminiyamu)

-Kukana kwamphamvu kwamafuta

-Umboni wamadzi ndi gasi

-High refractoriness (angagwiritsidwe ntchito pa 1450 ℃ mu mpweya ndi 1800 ℃ mu ndale chikhalidwe)

-Sichimakhudzidwa ndi dzimbiri ndipo sichinyowa ndi aluminiyamu yosungunuka kapena zinc yosungunuka.

-Kuuma kwakukulu

-Low friction coefficient

-Abrasion resistance

-Imatsutsana ndi ma acid oyambira komanso amphamvu

-Zomveka

-Mkulu wamakina mphamvu

Kugwiritsa ntchito Silicon Carbide:

-Zisindikizo zamakina, ma bearings, ma thrust bearings, etc

-Zolumikizana mozungulira

-Semiconductor ndi zokutira

-Pzotsatsa Pampu zigawo

-Zigawo za mankhwala

-Makalasi kwa mafakitale laser machitidwe.

- Ma reactor opitilira-otaya, osinthanitsa kutentha, ndi zina.

Mbali
Silicon carbide imapangidwa m'njira ziwiri:

1) Pressureless sintered silicon carbide

Pambuyo pazitsulo zopanda mphamvu za sintered silicon carbide zimakhazikika, chithunzi cha kristalo pansi pa 200X kuwala kwa microscope chimasonyeza kuti kugawa ndi kukula kwa makhiristo ndi yunifolomu, ndipo kristalo yaikulu sikudutsa 10μm.

2) Reaction sintered silicon carbide

Pambuyo pa zomwe sintered silicon carbide imagwira gawo lathyathyathya komanso losalala la zinthuzo, kristalo
kugawa ndi kukula pansi pa 200X kuwala kwa microscope ndi yunifolomu, ndipo zaulere za silicon sizidutsa 12%.
