Gutegura n'imiterere ya silicon carbide ceramics hakoreshejwe reaction sintering

Karuboni ya Silicon (SiC) ni imvange ya covalent igizwe na karuboni na silicon kandi izwiho imiterere yayo myiza, harimo kudashira cyane, kudashyuha cyane, kudashira cyane no kwangirika cyane. Iyi miterere ituma karuboni ya Silicon iba ibikoresho byiza cyane mu nganda zitandukanye, harimo iby’indege, imashini, ibikomoka kuri peteroli, gushongesha ibyuma n’ibikoresho by’ikoranabuhanga. By’umwihariko ikwiriye gukorwamo ibice bidashira ndetse n’ibice by’imiterere bishyuha cyane. Iterambere rya ceramics za silicon carbide zakozwe na reaction-sintered silicon carbide ryagize uruhare runini mu guteza imbere ikoreshwa ry’ibi bikoresho mu nganda.

Uburyo gakondo bwo gukoraibumba rya silikoni rya karubide rikozwe mu buryo bwa reaction-sinteredni ugukoresha ifu ya silicon carbide ivanze n'ifu nto ya karuboni. Uruvange runyura mu buryo bwa siliconization bushyuha cyane kugira ngo rukore ibikoresho by'ibumba binini. Ariko, ubu bukorikori gakondo ntibuburamo imbogamizi zabwo. Uburyo bwo gutwika burangwa no kumara igihe kirekire, ubushyuhe bwinshi n'ingufu nyinshi, bigatuma umusaruro ugabanuka. Uko ibisabwa n'inganda ku miterere n'imiterere ya silicon carbide bigenda birushaho kugorana, imbogamizi z'uburyo gakondo zigenda zigaragara cyane.

Mu myaka ya vuba aha, ishyirwaho ry'ifu ya silicon carbide nanopowders ryabaye igisubizo cyiza cyo kunoza imiterere ya silicon carbide ceramics. Gukoresha nanopowders bishobora gukora ceramics zifite ubucucike bwinshi kandi zifite imbaraga zo guhindagurika. Ariko, ikiguzi cya silicon carbide nanopowders ni kinini, akenshi kirenga Yuan 10.000 kuri toni, ibi bikaba ari imbogamizi ikomeye ku ikoreshwa rya benshi n'umusaruro mugari. Iki kibazo cy'ubukungu gisaba gushakisha ibindi bikoresho fatizo n'uburyo bwo gukora kugira ngo ikorwa rya silicon carbide ceramics rirusheho kuba ryiza kandi rihendutse.

Byongeye kandi, ubushobozi bwo gukora imiterere igoye n'ibice binini bifungura inzira nshya zo gukoresha silicon carbide ceramic. Inganda zikenera imiterere igoye n'ibikoresho bikora neza zishobora kungukirwa n'ubu buryo bushya bwo gutegura. Uburyo bworoshye bwo gushushanya no gukora ibintu byinshi bya silicon carbide ceramics nziza bishobora gutuma habaho iterambere rikomeye mu nzego nko mu kirere no mu by'ikoranabuhanga aho imikorere y'ibikoresho ari ingenzi cyane.
