Apo Sila SiC

Wehewehena:

Loaʻa i ka Silicon Carbide ka waiwai o ka pale maikaʻi loa i ka palaho, ka ikaika mechanical kiʻekiʻe, ka conductivity thermal kiʻekiʻe, ka lubrication ponoʻī maikaʻi i hoʻohana ʻia e like me nā alo sila, nā bearings a me nā paipu i loko o nā mokulele, nā mīkini, ka metallurgy, ka paʻi a me ka hoʻoluʻu ʻana, nā meaʻai, nā lāʻau lapaʻau, ka ʻoihana kaʻa a pēlā aku. Ke hui pū ʻia nā alo sic me nā alo graphite, ʻo ka friction ka mea liʻiliʻi loa a hiki ke hana ʻia i mau sila mechanical i hiki ke hana i nā koi hana kiʻekiʻe loa.

Nā Waiwai Kumu o Silicon Carbide:

-Haʻahaʻa ka nui

-Ke alakaʻi wela kiʻekiʻe (kokoke i ka alumini)

-Ke kūpaʻa haʻalulu wela maikaʻi

-Pale wai a me ke kinoea

-ʻO ke kūpaʻa kiʻekiʻe (hiki ke hoʻohana ʻia ma 1450 ℃ i ka lewa a me 1800 ℃ i ka lewa kūlike ʻole)

-ʻAʻole ia e hoʻopilikia ʻia e ka pala a ʻaʻole hoʻi e hoʻomaʻū me ka alumini i hoʻoheheʻe ʻia a i ʻole ka zinc i hoʻoheheʻe ʻia

-Paʻakikī kiʻekiʻe

-Ka helu haʻalulu haʻahaʻa

-Ke kū'ē ʻana i ka abrasion

-Kūʻē i nā waikawa kumu a me nā waikawa ikaika

-Hiki ke hoʻopololei ʻia

-Ikaika mīkini kiʻekiʻe

Noi ʻana o Silicon Carbide:

-Nā sila mīkini, nā bearings, nā bearings thrust, a pēlā aku

-Nā hono wili

-Semiconductor a me ka uhi ʻana

-Pnā hoʻolaha Nā ʻāpana pamu

-Nā ʻāpana kemika

-Nā aniani no nā ʻōnaehana laser ʻoihana.

- Nā reactors kahe mau, nā mea hoʻololi wela, a pēlā aku.

Hiʻona
Hoʻokumu ʻia ka Silicon carbide ma nā ʻano ʻelua:

1)Pka carbide silicon sintered me ka ʻole o ka ressure

Ma hope o ke kālai ʻia ʻana o ka mea silicon carbide sintered pressureless, hōʻike ka kiʻikuhi pae kristal ma lalo o ka microscope optical 200X i ka like ʻana o ka hoʻolaha ʻana a me ka nui o nā kristal, a ʻaʻole iʻoi aku ka kristal nui loa ma mua o 10μm.

2) Rka hana ʻana i ka silicon carbide sintered

Ma hope o ka hopena o ka silicon carbide sintered e mālama kemika i ka ʻāpana pālahalaha a laumania o ka mea, ʻo ke kristal
Ua like ka hoʻolaha a me ka nui ma lalo o ka microscope optical 200X, a ʻaʻole ʻoi aku ka nui o ka silicon manuahi ma mua o 12%.
