Carbide ya Silicon (SiC) ihinduranya ubushyuhe ikoreshwa cyane mu nzego z’imiti, ingufu, no kurengera ibidukikije bitewe n’ubushyuhe buhebuje - bwo kurwanya ubushyuhe, kurwanya ruswa, hamwe n’ubushyuhe bwinshi. Nyamara, imikorere yabo ishingiye cyane ku guhitamo ibikoresho, kandi guhuza ibikoresho bikwiye bigira ingaruka ku buryo butaziguye ubuzima bwa serivisi no gukora neza.
Ubwa mbere, silicon karbide ceramic nibikoresho byatoranijwe kubice byingenzi byo guhanahana ubushyuhe. Hejuru - karbide yera ya silicon (urugero, hejuru ya 98%) ifite ibintu byanduye cyane, byongera imbaraga zo guhangana nubushyuhe bwumuriro hamwe n’imiti ihindagurika, bigatuma bikwiranye cyane nibidukikije bifite itangazamakuru ryangirika nka acide ikomeye na base. Byongeye kandi, ubushyuhe bwayo bwinshi (hafi 120-150 W / m · K) butuma habaho ubushyuhe bwiza kandi bikagabanya gutakaza ingufu.
Icya kabiri, guhitamo ibikoresho bifunga kashe nabyo birakomeye. Ikirangantego cyicyuma gikunze kunanirwa mubushyuhe bwinshi, mugihe grafite cyangwa karibide ya silicon - ishingiye kubintu (nka reaction - bihujwe na silicon karbide hamwe na grafite ya grafite) bitanga imikorere yizewe mugihe nayo irwanya ibitero byimiti. Kubikorwa bikabije, ibyaribyo byose - silicon karbide yasudiwe irashobora gukuraho ibyago byo kunanirwa kashe, ariko kubiciro byinshi.
Byongeye kandi, ibyuma bihuza ibice (nka flanges nu miyoboro) mubusanzwe byubatswe kuva hejuru - ubushyuhe - bivangavanze (nka Inconel 600 cyangwa Hastelloy) kugirango bihuze nubushyuhe bwo hejuru - bwa karubide ya silikoni kandi birinde kwangirika kwamashanyarazi. Ubuvuzi bwo hejuru (nk'imyenda cyangwa isahani) burashobora kongera imbaraga zo kwambara no kurwanya okiside.
Muri make, guhitamo ibikoresho bya silicon karbide ihanahana ubushyuhe bisaba gutekereza cyane kubiranga itangazamakuru, ubushyuhe nubushyuhe, hamwe nubukungu bukora neza. Mugutezimbere guhuza umubiri wa ceramic silicon karbide, ibikoresho bifunga kashe, nibikoresho byicyuma bifasha, ibikoresho byizewe hamwe nubuzima bwa serivisi birashobora gukoreshwa cyane kugirango bishoboke gusaba inganda.
