Gukora uburyo bwo gukora silicon karbide ikora

Carbide ya silicon-reaction-ibintu byingenzi byubushyuhe bwo hejuru, hamwe nimbaraga nyinshi, ubukana bwinshi, kwihanganira kwambara cyane, kurwanya ruswa nyinshi hamwe no kurwanya okiside nyinshi nibindi byiza bihebuje, bikoreshwa cyane mumashini, ikirere, inganda zikora imiti, ingufu nibindi. imirima.

 

1. Gutegura ibikoresho bibisi

Gutegura ibishishwa bya silicon karbide yibikoresho byibanze cyane cyane ifu ya karubone na silikoni, muribwo karubone ishobora gukoreshwa mubintu bitandukanye birimo karubone, nka kokiya yamakara, grafite, amakara, nibindi, ifu ya silicon isanzwe itorwa hamwe nuduce. ubunini bwa 1-5μm hejuru yifu ya silicon. Ubwa mbere, ifu ya karubone na silikoni ivangwa mukigereranyo runaka, ukongeramo urugero rukwiye rwa binder na agent, hanyuma ukabyutsa neza. Uruvange noneho rushyirwa mumashini yumupira kugirango usya imipira kugirango urusheho kuvanga no gusya kugeza ingano yingingo iri munsi ya 1 mm.

2. Uburyo bwo kubumba

Uburyo bwo kubumba ni imwe mu ntambwe zingenzi mu gukora karubide ya silicon. Uburyo bukoreshwa muburyo bwo kubumba ni ugukanda, Gukora imashini bisobanura ko imvange ishyirwa mububiko kandi bigakorwa nigitutu cya mashini. Gufata ibishishwa bivanga kuvanga imvange n'amazi cyangwa ibishishwa kama, kuyitera mubibumbano binyuze muri siringi mugihe cya vacuum, no gukora ibicuruzwa byarangiye nyuma yo guhagarara. Guhindagurika k'umuvuduko uhagaze bivanga kuvanga mubibumbano, birinzwe na vacuum cyangwa ikirere kugirango habeho umuvuduko uhagaze, mubisanzwe kumuvuduko wa 20-30MPa.

3. Uburyo bwo gucumura

Gucumura nintambwe yingenzi mubikorwa byo gukora reaction ya-silicon karbide. Ubushyuhe bwo gucana, igihe cyo gucumura, ikirere cyangiza nibindi bintu bizagira ingaruka kumikorere ya carbide ya silicon. Mubisanzwe, ubushyuhe bwa sinteri ya silicon karbide ikora hagati ya 2000-2400 ℃, igihe cyo gucumura muri rusange ni amasaha 1-3, kandi ikirere cyo gucumura gikunze kuba inert, nka argon, azote, nibindi. Mugihe cyo gucumura, imvange izajya ikora imiti kugirango ikore kristu ya silicon. Muri icyo gihe, karubone nayo izakora imyuka yo mu kirere kugirango itange imyuka nka CO na CO2, bizagira ingaruka ku bwinshi no ku miterere ya karubide ya silicon. Kubwibyo, gukomeza ikirere gikwiye cyo gucumura nigihe cyo gucumura ni ngombwa cyane mugukora karbide ya silicon-reaction.

4. Nyuma yo kuvurwa

Carbide ya silicon reaction-isaba inzira nyuma yo kuvurwa nyuma yo gukora. Ibikorwa bisanzwe nyuma yubuvuzi ni ugukora, gusya, gusya, okiside nibindi. Izi nzira zagenewe kunonosora neza nuburinganire bwubutaka bwa silicon karbide. Muri byo, gusya no gusya ni uburyo busanzwe bwo gutunganya, bushobora kunoza kurangiza no kuringaniza karubide ya silicon. Oxidation irashobora gukora oxyde kugirango yongere imbaraga za okiside hamwe nubushakashatsi bwimiti ya silicon karbide.

Muri make, gukora silicon karbide ikora ni inzira igoye, ikeneye kumenya tekinoloji nuburyo butandukanye, harimo gutegura ibikoresho fatizo, uburyo bwo kubumba, uburyo bwo gucumura hamwe na nyuma yubuvuzi. Gusa nukumenya neza tekinoroji hamwe nibikorwa birashobora gukorwa neza murwego rwohejuru rwibikoresho bya silicon carbide ibikoresho kugirango bikemurwe bikenewe mubikorwa bitandukanye.
