Ikintu kitari icyuma kigizwe na silikoni na azote, nitride ya silicon (Si3N4) nacyo ni ibikoresho bya ceramique byateye imbere hamwe n’imiterere ihuza imiterere y’imashini, ubushyuhe, n’amashanyarazi. Byongeye kandi, ugereranije nandi mafumbire menshi, ni ceramic ikora cyane hamwe na coefficente yo kwagura ubushyuhe buke itanga imbaraga zo guhangana nubushyuhe bwiza.
Ibiranga
Bitewe nubushobozi buke bwo kwagura ubushyuhe, ibikoresho bifite imbaraga nyinshi zo guhangana nubushyuhe bukabije hamwe no gukomera kuvunika. Ibikorwa bya Si3N4 birwanya ingaruka no guhungabana. Ibi bikoresho birashobora kwihanganira ubushyuhe bwibikorwa bigera kuri 1400 ° C kandi birwanya imiti, ingaruka zibora, hamwe nibyuma byashongeshejwe nka aluminium, hamwe na acide nibisubizo bya alkaline. Ikindi kintu kiranga ubwinshi bwacyo. Ifite ubucucike buke bwa 3,2 kugeza kuri 3,3 g / cm3, bikaba byoroshye nka aluminium (2,7 g / cm3), kandi ifite imbaraga zo kugonda cyane ≥900 MPa.
Byongeye kandi, Si3N4 irangwa no kurwanya cyane kwambara kandi ikarenza imiterere yubushyuhe bwo hejuru bwibyuma byinshi, nkimbaraga zubushyuhe bwo hejuru hamwe no guhangana n’ibikurura. Itanga imvange isumba iyindi ya creep na okiside irwanya kandi ikarenza ubushobozi bwubushyuhe bwo hejuru bwubwinshi bwibyuma. Bitewe nubushyuhe buke hamwe no kwihanganira kwambara, irashobora kwihanganira ibihe bikaze mubikorwa bikenerwa cyane ninganda. Byongeye kandi, nitride ya silicon ninzira nziza mugihe hakenewe ubushyuhe bwo hejuru hamwe nubushobozi bwo gutwara ibintu byinshi.
Ibyiza
Gukomera cyane
Strength Imbaraga nziza
Ubucucike buke cyane
● Kurwanya imbaraga zidasanzwe zidasanzwe
Temperature Ubushyuhe bukabije bwo gukora mukwangiza ikirere
Uburyo bwo kubyaza umusaruro
Inzira eshanu zitandukanye zikoreshwa mugukora nitride ya silicon-biganisha kubikoresho bitandukanye byakazi hamwe nibisabwa.
SRBSN (nitride ya silicon)
GPSN (igitutu cya gaze cyacumuye silicon nitride)
HPSN (nitride ya silicon ishyushye)
HIP-SN (ishyushye rya nitride ya silicon ishyushye)
RBSN (nitride ya silicon)
Muri ibi bitanu, GPSN nuburyo bukoreshwa cyane mubikorwa.
Ingero zo gusaba
Imipira nibintu bizunguruka kumucyo
Bitewe no gukomera kwinshi kuvunika hamwe nibintu byiza bya tribologiya, ceramika ya silicon nitride ikwiriye gukoreshwa nkumupira hamwe nibintu bizunguruka kumucyo, ibyuma bisobanutse neza, ibikoresho bikora ceramic biremereye cyane, hamwe nibice byimodoka. Byongeye kandi, tekinike yo gusudira ikoresha ibikoresho 'birwanya ubushyuhe bukabije bwumuriro hamwe nubushyuhe bwo hejuru.
Ubushyuhe bwo hejuru
Byongeye kandi, imaze igihe kinini ikoreshwa mubushyuhe bwo hejuru. Kuba ari kimwe mu bikoresho bike bya monolithic ceramic bishobora kwihanganira ihungabana rikabije ry’ubushyuhe hamwe n’ubushyuhe bukabije bwakozwe na moteri ya roketi ya hydrogen / ogisijeni.
Inganda zitwara ibinyabiziga
Kugeza ubu, ibikoresho bya nitride ya silicon bikoreshwa cyane cyane mu nganda zikoresha amamodoka mu gusaba ibice bya moteri hamwe n’ibikoresho bikoresha moteri, nka turbocharger ya inertia yo hasi no kugabanya moteri ya moteri hamwe n’ibyuka bihumanya ikirere, ibyuma bimurika kugirango bitangire vuba, ibyuma bisohora gaze kugira ngo byihute, na rocker yamaboko ya moteri ya gaze kugirango igabanuke.
Inganda za elegitoroniki
Bitewe numuriro wamashanyarazi utandukanye, mubikorwa bya microelectronics, nitride ya silicon ikoreshwa cyane nka insulator na bariyeri ya chimique mugukora imiyoboro ihuriweho kugirango ipakire neza ibikoresho. Nitride ya Silicon ikoreshwa nkurwego rwa passivation ifite inzitizi nyinshi yo gukwirakwiza kurwanya ioni ya sodium namazi, ibyo bikaba aribintu bibiri byingenzi bitera kwangirika no guhungabana muri mikorobe. Muri capacitori kubikoresho bisa, ibintu nabyo bikoreshwa nkumuriro wamashanyarazi hagati ya polysilicon.
Umwanzuro
Silicon nitride ceramics nibikoresho byingirakamaro. Buri bwoko bwiyi ceramic ifite ibintu byihariye bituma bigira akamaro mubice bitandukanye. Gusobanukirwa nubwoko bwinshi bwa silicon nitride ceramics byoroshe guhitamo icyiza kumurongo watanzwe.
