mmeghachi omume sintering silicon carbide bụ usoro maka ịkwadebe ihe seramiiki dị elu. Ọ na-emeghachi ma na-akụ silicon carbide ntụ ntụ na kemịkalụ ndị ọzọ n'okpuru ọnọdụ okpomọkụ dị elu iji mepụta njupụta dị elu, ike siri ike, akwa mkpuchi mkpuchi na ihe ndị na-eguzogide corrosion dị elu.
1. Usoro nkwadebe. Usoro nkwadebe nke reactive sintering silicon carbide na-agụnyekarị usoro abụọ: mmeghachi omume na sintering. N'oge mmeghachi omume, silicon carbide ntụ ntụ na-emeghachi omume na kemịkalụ ndị ọzọ na oke okpomọkụ iji mepụta ogige nwere ebe mgbaze dị ala, dị ka alumina, boron nitride na calcium carbonate. Ogige ndị a nwere ike ịrụ ọrụ dị ka ndị na-ekekọta ihe na ihe ndị na-ejuputa iji nyere aka mee ka ikike nke njikọ na mmiri dị na silicon carbide powders na-ebelata pores na ntụpọ na ihe. N'ebe a na-agbagharị agbagharị, ngwaahịa mmeghachi omume na-agbanye na okpomọkụ dị elu iji mepụta ihe seramiiki siri ike. Ihe ndị dị ka okpomọkụ, nrụgide na ikuku nchebe dị mkpa ka a na-achịkwa n'ime usoro nchịkọta iji hụ na ihe ahụ nwere arụmọrụ dị mma. Ihe onwunwe seramiiki silicon carbide enwetara nwere njirimara nke ike siri ike, ike dị elu, nguzogide corrosion dị elu na nkwụsi ike dị elu.
2. Ngwongwo. silicon carbide na-emeghachi omume nwere ọtụtụ ihe mara mma, na-eme ka a na-eji ya n'ọtụtụ ebe. Nke mbụ, silicon carbide seramiiki ihe siri ike nke ukwuu ma nwee ike belata ihe ndị siri ike dị ka nchara. Nke abuo, silicon carbide seramiiki ihe nwere ezigbo nguzogide na-eyi ma enwere ike iji ya ogologo oge n'okpuru ọnọdụ siri ike dị ka okpomọkụ dị elu na nrụgide dị elu. Tụkwasị na nke ahụ, ihe ndị na-emepụta ihe ndị dị na silicon carbide nwere nnukwu nkwụsị nke corrosion na nkwụsi ike dị elu, a pụkwara iji ya mee ihe ruo ogologo oge na gburugburu ebe obibi na okpomọkụ dị elu.
3. Ngwa ngwa. A na-eji silicon carbide emeghachi omume n'ọtụtụ mpaghara. Dịka ọmụmaatụ, n'ime ụlọ ọrụ mmepụta ihe, a na-eji silicon carbide seramiiki eme ihe n'ọtụtụ ebe na abrasives, ịkpụ ngwá ọrụ na-eyi akụkụ. Ọkpụkpụ ya dị elu na nguzogide iyi na-eme ka ọ baa uru maka ịcha, ịkụcha na ịkwanye
Kwesịrị ekwesị maka polishing na ubi ndị ọzọ. N'ime ụlọ ọrụ kemịkalụ, silicon carbide seramiiki nwere ike iji mepụta kemịkalụ dị ka sulfuric acid na acid siri ike dị ka hydrofluoric acid n'ihi nnukwu nguzogide corrosion ha na nkwụsi ike dị elu. N'ihe gbasara ikuku na agbachitere, silicon carbide ceramic ihe nwere ike iji mee ka mkpuchi ngwa agha na ihe nchebe ọkụ maka ụgbọ elu dị elu. Na mgbakwunye, silicon carbide seramiiki ihe nwekwara ike iji na biomedical ubi nke artificial nkwonkwo na orthopedic ngwá ọrụ ịwa ahụ, n'ihi na ha nwere ezi biocompatibility na-eyi nguzogide.
mmeghachi omume sintering silicon carbide bụ usoro maka ịkwadebe ihe seramiiki dị elu. Ọ na-emeghachi ma na-akụ silicon carbide ntụ ntụ na kemịkalụ ndị ọzọ n'okpuru ọnọdụ okpomọkụ dị elu iji mepụta njupụta dị elu, ike siri ike, akwa mkpuchi mkpuchi na ihe ndị na-eguzogide corrosion dị elu. Silicon carbide seramiiki ihe nwere ezigbo ihe, dị ka ike siri ike, akwa mkpuchi akwa, nguzogide corrosion dị elu na nkwụsi ike dị elu, yabụ a na-eji ya n'ọtụtụ ebe dị ka nrụpụta, ụlọ ọrụ kemịkalụ, ikuku ikuku na nchekwa na ubi biomedical.
