Ibisobanuro:

Silicon Carbide ifite umutungo wokurwanya-kwangirika kwinshi, imbaraga za mashini nyinshi, ubushyuhe bwumuriro mwinshi, kwisiga neza bikoreshwa nkisura ya kashe, imiyoboro hamwe nigituba mubyogajuru, imashini, metallurgie, gucapa no gusiga irangi, ibiribwa, imiti, inganda zimodoka nibindi ku. Iyo sic isura ihujwe na grafite isura yo guterana ni ntoya kandi irashobora gukorwa mubidodo bya mashini zishobora gukora mubisabwa cyane.

Silicon Carbide Ibintu Byibanze:

-Ubucucike buke

-Amashanyarazi menshi (hafi ya aluminium)

-Kurwanya ubushyuhe bwiza

-Amazi ya gaze na gaze

-Kunanirwa cyane (birashobora gukoreshwa kuri 1450 ℃ mu kirere na 1800 ℃ mu kirere kidafite aho kibogamiye)

-Ntabwo iterwa no kwangirika kandi ntutose hamwe na aluminiyumu yashonze cyangwa zinc yashonze

-Gukomera cyane

-Coefficient nkeya

-Kurwanya Abrasion

-Irwanya aside yibanze kandi ikomeye

-Polisheable

-Imbaraga zikomeye

Silicon Carbide Porogaramu:

-Ikidodo cya mashini, ibyuma, gusunika, nibindi

-Guhinduranya ingingo

-Igice cya kabiri

-Pamatangazo Ibikoresho byo kuvoma

-Ibigize imiti

-Indorerwamo za sisitemu yinganda.

- Imiyoboro ikomeza-itemba, guhinduranya ubushyuhe, nibindi.

Ikiranga
Carbide ya Silicon ikorwa muburyo bubiri:

1) P.ressureless yacumuye silicon karbide

Nyuma yo gushiramo ibikoresho bya karibide ya silicon idafite ingufu, igishushanyo mbonera cya kristu munsi ya microscope ya 200X optique yerekana ko ikwirakwizwa nubunini bwa kristu ari kimwe, kandi kristu nini ntirenza 10 mm.

2) R.eaction yacumuye silicon karbide

Nyuma yo kubyitwaramo silicon karbide ya chimique ivura igice kiringaniye kandi cyoroshye cyibikoresho, kristu
gukwirakwiza nubunini munsi ya 200X optique microscope irasa, kandi ibirimo silicon yubusa ntibirenza 12%.
