Uburyo bwo gukaraba silicon carbide bukoresha uburyo bwo gukora ibikoresho bya ceramic bifite imikorere myiza. Ubu buryo bukoresha uburyo bwo kuvura ubushyuhe bwa karuboni na silicon ku bushyuhe bwinshi kugira ngo butume bigira ingaruka ku bikoresho bya silicon carbide.
1. Gutegura ibikoresho fatizo. Ibikoresho fatizo bya silicon carbide irimo reaction-sintered silicon carbide birimo isoko ya karuboni n'isoko ya silicon. Isoko ya karuboni akenshi iba umukara wa karuboni cyangwa polymer irimo karuboni, mu gihe isoko ya silicon ari silika ifu. Ibi bikoresho fatizo bigomba gushwanyaguzwa, gupimwa no kuvangwa kugira ngo hamenyekane ingano imwe y'uduce, ndetse no kugenzura imiterere yabyo kugira ngo haboneke ceramics za silicon carbide nziza mu gihe cyo gushyushya.
2. Ishusho. Shyira ibikoresho fatizo bivanze mu ibumba ryo gushushanya. Hari ubwoko bwinshi bw'uburyo bwo gushushanya, bukunze gukoreshwa ari ugushyiraho icyuma no gushushanya. Gushyiraho icyuma ni ugukanda ifu y'ibikoresho fatizo munsi y'igitutu kugira ngo ikore, mu gihe gushushanya icyuma ari ibikoresho fatizo bivanze n'ubudodo, bishyirwa mu ibumba binyuze muri syringe kugira ngo bikore. Nyuma yo gukora, ni ngombwa gukora uburyo bwo gukuramo icyuma cya ceramic mu ibumba.
3. Gutunganya ubushyuhe. Umubiri wa keramike wakozwe ushyirwa mu itanura ritunganya ubushyuhe kugira ngo ucucume. Uburyo bwo gucucume bugabanyijemo ibice bibiri: icyiciro cya karuboni n'icyiciro cya karuboni. Mu cyiciro cya karuboni, umubiri wa keramike ushyushywa kugeza ku bushyuhe bwinshi (ubusanzwe hejuru ya 1600 ° C) munsi y'ikirere kidashyushye, maze isoko ya karuboni igakorana n'isoko ya silicon kugira ngo ikore karuboni ya silicon. Mu cyiciro cyo gucucume, ubushyuhe buzamurwa kugeza ku bushyuhe bwinshi (ubusanzwe hejuru ya 1900 ° C), bigatuma habaho kongera gucucuma no kwiyongera hagati y'uduce twa karuboni ya silicon. Muri ubu buryo, ubucucike bw'umubiri wa karuboni ya silicon burushaho kwiyongera, mu gihe ubukana n'ubudahangarwa byoroshye nabyo birushaho kwiyongera.
4. Kurangiza. Ibara ry'icyuma gikozwe mu cyuma rigomba kurangizwa kugira ngo haboneke imiterere n'ingano byifuzwa. Uburyo bwo kurangiza burimo gusya, gukata, gucukura, nibindi. Bitewe n'ubukana bwinshi bw'ibikoresho bya silicon carbide, biragoye kurangiza, bisaba gukoresha ibikoresho byo gusya neza cyane n'ibikoresho byo gutunganya.
Muri make, inzira yo gukora carbide ya silikoni irimo gukora ibikoresho fatizo, gushushanya, gutunganya ubushyuhe no kurangiza. Muri byo, intambwe y'ingenzi ni inzira yo gutunganya ubushyuhe, kugenzura kwayo ni ingenzi kugira ngo ubone ibikoresho bya silikoni byiza. Ni ngombwa kugenzura ubushyuhe, ikirere, igihe cyo gufata n'ibindi bintu byo gutunganya ubushyuhe kugira ngo harebwe ko reaction ihagije, crystallization yuzuye kandi ubucucike buri hejuru.
Akamaro k'uburyo bwo gukora carbide ya silikoni ikozwe muri reaction-sintered ni uko ibikoresho bya silikoni bifite ubukana bwinshi, imbaraga nyinshi, ubushobozi bwo kwangirika cyane kandi bihamye mu bushyuhe bwinshi bishobora gutegurwa. Iki gikoresho ntabwo gifite ubushobozi bwiza bwo gukora ibyuma gusa, ahubwo kinafite ubushobozi bwo kurwanya ingese n'ubushyuhe bwinshi. Ibikoresho bya silikoni bishobora gukoreshwa mu gukora ibice bitandukanye by'ubuhanga, ibifunga bya silikoni, ibikoresho byo gutunganya ubushyuhe, keramike y'itanura n'ibindi. Muri icyo gihe, ibikoresho bya silikoni bishobora no gukoreshwa mu bikoresho bya semiconductor, ingufu z'izuba, ibikoresho bya rukuruzi n'ibindi.
Muri make, karubide ya silikoni ikoresha uburyo bwo gukamura ibintu ni ingenzi mu gutegura ibikoresho bya seramike bifite imikorere myiza. Uburyo bwo kubitunganya busaba kugenzura neza buri gice kugira ngo ubone ibikoresho bya silikoni bifite imiterere myiza. Ibikoresho bya silikoni bikoresha uburyo bwo gukamura ibintu bifite imiterere myiza ya mekanike, birwanya ingese n'imiterere y'ubushyuhe bwinshi, kandi bifite amahirwe menshi yo gukoreshwa mu nzego zitandukanye z'inganda n'ubumenyi.
