Amashami yo gukoresha SiC/SiC

SiC/SiCifite ubushobozi bwo kurwanya ubushyuhe kandi izasimbura superalloy mu ikoreshwa rya moteri y'ikirere

Intego ya moteri zikoresha amashanyarazi agezweho ni ugukoresha ingufu nyinshi mu gukurura no gupima uburemere. Ariko, bitewe n’ubwiyongere bw’ingano y’imbaraga mu gukurura no gupima uburemere, ubushyuhe bw’ingufu zinjira mu mashini zikoresha amashanyarazi bukomeza kwiyongera, kandi sisitemu y’ibikoresho bya superalloy isanzwe iragoye kuzuza ibisabwa na moteri zikoresha amashanyarazi agezweho. Urugero, ubushyuhe bw’ingufu zinjira mu mashini zisanzwe zifite igipimo cyo gukurura no gupima uburemere cy’urwego rwa 10 bwageze kuri 1500℃, mu gihe ubushyuhe bw’impuzandengo bw’ingufu zinjira mu mashini zifite igipimo cyo gukurura no gupima uburemere cya 12 ~ 15 buzarenga 1800℃, ibi bikaba birenga cyane ubushyuhe bw’ingufu zikoreshwa mu gukurura no gupima uburemere bw’ingufu n’ibinyabutabire bivanze n’ibyuma.

Kuri ubu, superalloy ishingiye kuri nikeli ifite ubushobozi bwo kwihanganira ubushyuhe ishobora kugera kuri dogere 1100 gusa. Ubushyuhe bwa SiC/SiC bushobora kongerwaho kugeza kuri dogere 1650, ibi bikaba bifatwa nk'ibikoresho byiza cyane byo mu kirere bishyushye.

Mu Burayi no muri Leta Zunze Ubumwe za Amerika n'ibindi bihugu byateye imbere mu by'indege,SiC/SiCByakoreshejwe mu buryo bufatika kandi bikorerwa mu bice bitagira moteri, harimo M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 n'ubundi bwoko bwa moteri za gisirikare/iza gisivili; Gukoresha ibice bizenguruka biracyari mu rwego rwo gutera imbere no kugerageza. Ubushakashatsi bw'ibanze mu Bushinwa bwatangiye buhoro buhoro, kandi hari icyuho kinini hagati yabwo n'ubushakashatsi bwakoreshejwe mu buhanga mu bihugu by'amahanga, ariko kandi bwageze ku ntego.

Muri Mutarama 2022, ubwoko bushya bwa ceramic matrix composite ni bwo kaminuza y’uburengerazuba bwa polytechnical ikoresha ibikoresho byo mu gihugu mu kubaka disiki ya moteri y’indege irangiza neza ikizamini cya mbere cyo kuguruka, kandi ni ubwa mbere rotor ya ceramic matrix composite rotor yo mu gihugu ifite urubuga rwo gupima indege, ariko kandi no guteza imbere ibice bya ceramic matrix composite ku modoka idafite umudereva (uav)/drone nini.
