Njirimara nke silicon carbide recrystallized
silicon carbide recrystallized (R-SiC) bụ ihe na-arụ ọrụ dị elu nke nwere ike nke abụọ na diamond, nke a na-etolite na okpomọkụ dị elu karịa 2000 ℃. Ọ na-ejigide ọtụtụ ihe ndị mara mma nke SiC, dị ka ike okpomọkụ dị elu, nguzogide corrosion siri ike, nguzogide oxidation magburu onwe ya, ezigbo nkwụsị ọkụ ọkụ na ihe ndị ọzọ.
● Magburu onwe n'ibu Njirimara. silicon carbide recrystallized nwere ike dị elu na isi ike karịa eriri carbon, mmetụta dị elu na-eguzogide, nwere ike ịrụ ọrụ dị mma na gburugburu okpomọkụ dị oke egwu, nwere ike ịrụ ọrụ counterbalance ka mma n'ọnọdụ dị iche iche. Tụkwasị na nke ahụ, ọ na-enwekwa mgbanwe dị mma na ọ dịghị emebi ngwa ngwa site na ịgbatị na ịgbatị, nke na-eme ka arụmọrụ ya dịkwuo mma.
● Nnukwu nguzogide corrosion. Carbide silicon recrystallized nwere nnukwu ihe mgbochi corrosion na-eguzogide ụdị mgbasa ozi dị iche iche, nwere ike igbochi mmebi nke mgbasa ozi dị iche iche na-emebi emebi, nwere ike ịnọgide na-arụ ọrụ ya ruo ogologo oge, nwee nkwekọ siri ike, ka o wee nwee ogologo ndụ ọrụ. Tụkwasị na nke ahụ, ọ na-enwekwa nkwụsi ike nke okpomọkụ dị mma, nwere ike ime mgbanwe na mgbanwe mgbanwe okpomọkụ, melite mmetụta ngwa ya.
● Ime ihe adịghị ebelata. N'ihi na usoro nkwụsịtụ adịghị ebelata, ọ dịghị nrụgide fọdụrụnụ ga-eme ka nrụrụ ma ọ bụ mgbawa nke ngwaahịa ahụ, na akụkụ ndị nwere ọdịdị dị mgbagwoju anya na nkenke dị elu nwere ike ịkwadebe.
