Silicon nitride seramiiki nwere ọmarịcha anụ ahụ, kemịkalụ na nrụ ọrụ
Silicon nitride ceramics nwere uru pụtara ìhè: njupụta dị ala, nguzogide dị elu, mmanye onwe ya, nguzogide corrosion. Oke Si3N4ceramics na-egosipụtakwa ike mgbaji dị elu, njirimara modulus dị elu na mmanu onwe onye, nke nwere ike ịbụ ezigbo nguzogide ụdị uwe dị iche iche ma na-eguzogide ọnọdụ siri ike nke nwere ike ime ka ihe ndị ọzọ seramiiki gbawaa, nrụrụ ma ọ bụ daa, gụnyere oke okpomọkụ, nnukwu ọdịiche okpomọkụ, na ultra-high agụụ.
Ngwa isi nke Silicon Nitride ceramics
Mmụta mekanịkal injinịa: Silicon nitride ceramics nwere isi ike dị elu, ezigbo nguzogide eyi na nguzogide corrosion, a na-ejikwa ya na mpaghara injinia. Enwere ike iji ya mepụta akụkụ ndị dị ka bearings, akàrà, ngwá ọrụ ịkpụ na nozzles na okpomọkụ dị elu na ọsọ ọsọ, na-enye ọrụ dị mma na ogologo ndụ.
Ụlọ ọrụ ụgbọ ala: N'ihi nkwụsi ike dị elu ma na-eyi nguzogide silicon nitride ceramics, a na-eji ya na-emepụta ihe ndị na-emepụta ụgbọ ala. Silicon nitride ceramics nwere ike iji mee akụkụ engine dị elu dị ka mgbanaka piston, cylinder liners na valves, na-enyere aka melite arụmọrụ mmanụ ọkụ na ibelata ikuku.
Igwe ikuku: Igwe ọkụ dị arọ, ike dị elu na oke okpomọkụ nke ceramics silicon nitride na-eme ka ha bụrụ ihe dị mma maka ngwa ikuku. Enwere ike iji ya rụpụta ihe ndị dị mkpa dị ka akụrụngwa injin, eriri turbine, ihe ndị dịpụrụ adịpụ na-ekpo ọkụ na nchekwa ikuku ụgbọ elu iji gboo ihe achọrọ nke okpomọkụ dị elu, nrụgide dị elu na oke gburugburu.
Ụlọ ọrụ kemịkalụ: A na-eji seramiki silicon nitride eme ihe n'ọtụtụ ebe na ụlọ ọrụ kemịkalụ n'ihi nkwụsi ike kemịkalụ ha dị mma na nguzogide corrosion. Enwere ike iji seramiki silicon nitride rụpụta arịa mmeghachi omume kemịkalụ, ndị na-ebu ihe na-akpata, acid na alkali na-eguzogide akụrụngwa na ọkpọkọ, ma nwee ike iguzogide mgbasa ozi na-emebi emebi na ọnọdụ okpomọkụ dị elu.
Optoelectronics: Silicon nitride ceramics nwere ezigbo ngwa anya na eletrọnịkị, yabụ na ha nwere ngwa dị mkpa na ngalaba optoelectronics. Enwere ike iji ya na-emepụta okpomọkụ dị elu na nnukwu ike fiber amplifiers, lasers, ngwa nkwurịta okwu ngwa anya na Windows ngwa anya ... wdg, na ezigbo nnyefe ngwa anya na nkwụsi ike ọkụ.
