ʻOi aku ka maikaʻi o ka silikon nitride ceramics ma mua o ka metala ma nā ʻano he nui. Hoʻohana nui ʻia lākou i nā ʻoihana aerospace, nuklea, petrochemical, textile a me nā ʻenehana ʻenekinia.
Pōmaikaʻi:
· Ka waiwai mechanical maikaʻi
· Haʻahaʻa puʻupuʻu nui
· Ka ikaika kiʻekiʻe a me ka paʻakikī
· Haʻahaʻa friction coefficient
· Ka hana lubricating maikaʻi
· Kūʻē i ka ʻino metala
· Hoʻopili uila

ʻOi aku ka maikaʻi o ka silikon nitride ceramics ma mua o nā mea ʻē aʻe ma muli o kona kūpaʻa haʻalulu wela. ʻAʻole ia e pōʻino i nā wela kiʻekiʻe, no laila hoʻohana ʻia no nā ʻenekini kaʻa a me nā ʻāpana no nā turbines kinoea, me ka rotor turbocharger.
Hāʻawi ʻo Ortech i kahi ʻohana piha o nā mea Silicon Nitride. Loaʻa i kēia mau mea nā hiʻohiʻona nui: ʻAʻohe mea paʻa i ke kila, ʻElua ʻoi aku ka paʻakikī e like me ke kila mea hana, Ke kūpaʻa kemika maikaʻi a 60% emi ke kaumaha ma mua o ke kila.
ʻO Silicon nitrides (Si3N4) kahi ʻano o nā seramika ʻenehana kiʻekiʻe i hōʻike ʻia e ka ikaika kiʻekiʻe, ka paʻakikī a me ka paʻakikī a me ka paʻa kemika maikaʻi loa.
Ua ʻike ʻia ʻo Silicon nitride i ka waena o ke kenekulia ʻumikūmāiwa akā ʻaʻole ia i hāʻawi iā ia iho i ka maʻalahi o ka hana ʻana, ma muli o kona ʻano paʻa covalently. Ua alakaʻi mua kēia i ka hoʻomohala ʻana i ʻelua ʻano silicon nitride, reaction-bonded silicon nitride (RBSN) a me hot pressed silicon nitride (HPSN). Ma hope mai, mai ka makahiki 1970, ua hoʻomohala ʻia ʻelua ʻano ʻano ʻē aʻe: nitride silicon sintered (SSN), ʻo ia hoʻi nā sialons, a me ka sintered reaction-bonded silicon nitride (SRBSN).
ʻO ka makemake i kēia manawa i nā mea ʻenehana kumu silicon nitride i hoʻomohala maoli ʻia mai ka noiʻi ʻana i nā makahiki 1980 i nā ʻāpana seramika no ka turbine gas a me nā ʻenekini piston. Ua manaʻo ʻia he māmā ke kaumaha o ka ʻenekini, i hana nui ʻia me nā ʻāpana silicon nitride, e like me ka sialon, a hiki ke hana i nā wela kiʻekiʻe ma mua o nā ʻenekini kuʻuna e hopena i ka ʻoi aku ka maikaʻi. ʻO ka hope naʻe, ʻaʻole i hoʻokō ʻia kēia pahuhopu ma muli o nā kumu he nui e pili ana i ke kumukūʻai, ka paʻakikī o ka hana pono ʻana i nā ʻāpana a me ke ʻano palupalu o nā seramika.
Eia nō naʻe, ua alakaʻi kēia hana i ka hoʻomohala ʻana i kekahi mau noi ʻoihana ʻē aʻe no nā mea i hoʻokumu ʻia i ka nitride silicon, e like me ka hoʻokumu ʻana i ka metala, ka lole ʻenehana a me ka hoʻoheheʻe ʻana i ka metala.
ʻO nā ʻano like ʻole o ka silicon nitride, RBSN, HPSN, SRBSN a me SSN, ka hopena mai kā lākou ʻano hana hana, e hoʻomalu ana i kā lākou hopena a me nā noi.
