Dia3mm SiC bọọlụ seramiiki Silicon carbide seramiiki Polycrystalline

Seramiki SiC nwere ike siri ike nke ukwuu, nke abụọ karịa dayamọnd, nke na-eme ka ọ dị mma n'igbochi iyi, iguzogide ọkọ na akụkụ ndị ọzọ. N'otu oge ahụ, ọ nwekwara ike ịgbagọ agbagọ na ike nrụgide, ọ nwekwara ike ịnọgide na-arụ ọrụ kwụsiri ike na gburugburu ebe siri ike dịka okpomọkụ dị elu na nrụgide dị elu. Ebe agbaze nke seramiki silicon carbide dị elu ruo 2700℃, nke nwere ike ịgba ọsọ ruo ogologo oge na gburugburu ebe okpomọkụ dị elu ma ọ dịghị mfe ịgbanwe ma mebie. Na mgbakwunye, seramiki silicon carbide nwere ezigbo iguzogide nchara megide ọtụtụ asịd, ntọala, nnu na kemịkalụ ndị ọzọ, ma dabara adaba maka ọtụtụ gburugburu ebe obibi kemịkalụ. N'ikpeazụ, ọ nwekwara obere coefficient nke mgbasawanye okpomọkụ, nke nwere ike ịnọgide na-enwe nkwụsi ike nha na gburugburu ebe okpomọkụ na-agbanwe.

Ngwa nke seramiiki SiC

A na-eji seramiiki silikọn carbide eme ihe nke ukwuu n'ịmepụta ihe ndị na-anaghị emegharị ahụ, dịka ihe mkpuchi ọkụ, mkpuchi ọkụ, na akpa okpomọkụ dị elu, n'ihi oke okpomọkụ na iguzogide nchara ya. Ka ọ dị ugbu a, a na-ejikarị ike ya dị ala nke abrasive na ọbụna ọka eme ihe n'ịcha, egweri, ịchacha na usoro ndị ọzọ. Paadị breeki silikọn carbide nwere oke njikọ nke esemokwu na nguzogide abrasion, nke enwere ike iji na sistemụ breeki nke ụgbọala, ụgbọ oloko na ụgbọ njem ndị ọzọ. Na mgbakwunye, enwere ike itinye ya na efere mgbochi iyi, ihe na-ebufe ihe, igwe mbuli elu bọket na ngwa ndị ọzọ iji belata iyi ngwa ọrụ nke ọma. Ihe mgbanwe okpomọkụ silikọn carbide nwere arụmọrụ mgbanwe okpomọkụ dị mma ma ejiri ya mee ihe nke ukwuu na ike eletrik, mmanụ ala, kemịkalụ na ụlọ ọrụ ndị ọzọ. N'ikpeazụ, akụkụ injin seramiiki silikọn carbide nwere ike ịnọgide na-arụ ọrụ kwụsiri ike na gburugburu okpomọkụ dị elu na nrụgide dị elu, na-eme ka ike injin na arụmọrụ ka mma.
