Seramiki alumina siri ike: ihe ndị dị elu nwere arụmọrụ dị mma

A na-ejikarị seramiiki alumina eme ihe n'ọtụtụ ebe n'ihi uru ha dị ka ike siri ike na nkwụsi ike kemịkalụ siri ike. Agbanyeghị, ike ha na-agbawa agbawa na-ebelata oke ojiji ha. Seramiiki alumina siri ike malitere ịpụta ma dozie nsogbu a nke ọma.

 Seramiki alumina siri ikeenwere ike ime ka ọ sie ike n'ụzọ dị iche iche. Ndị a na-ahụkarị gụnyere ike siriko, nke na-eme ka ike dịkwuo mma site n'itinye ZrO₂ na alumina ma jiri mgbanwe nkebi ya na usoro ndị ọzọ; ike siriko na eriri, itinye ajị SiC, Si₃N₄ ma ọ bụ C, eriri SiC iji mee ka ọwa mgbasa mgbawa dịkwuo elu ma na-eri ike mgbawa; ike siriko bụ itinye irighiri modulus dị elu dị ka SiC na TiC iji gbapụ ma bifurcate mgbawa.

 Ike flexural na ike mmetụta nke seramiki alumina siri ike na-akawanye mma nke ukwuu. Dịka ọmụmaatụ, ike flexural nke seramiki alumina siri ike nke zirconia nwere ike iru 480MPa, ike mmetụta ahụ bụkwa 7MPam1/2.

 N'ihe gbasara ojiji, n'ọhịa ahụike, a na-eji ya emepụta ihe e ji etinye ezé na nkwonkwo arụ ọrụ n'ihi na ọ dị mma na njikọ ya na oke ike ya, nke nwere ike ibelata nsogbu; n'ọhịa semiconductor, dị ka ihe eji echekwa ihe na ngwaọrụ, a na-eji ya na IGBTs ụgbọ ala eletrik, wdg. n'ihi oke okpomọkụ ya, mkpuchi ya na ike igwe; na ngwaọrụ ịkpụ, ọ nwere ike ịnọgide na-eguzosi ike na okpomọkụ dị elu ma na-arụpụta nhazi nke ígwè a kpụrụ akpụ na alloys. Seramiki alumina siri ike na-enwu n'ọtụtụ ubi na arụmọrụ ha dị mma. Seramiki Chemshun na-enye seramiki alumina siri ike nke nwere iguzogide abrasion nri abalị na iguzogide mmetụta maka sistemụ njikwa ihe buru ibu.
