Reaction sintering silicon karbide nuburyo bwo gutegura ibikoresho byiza bya ceramic. Ifata kandi ikanda ifu ya karubide ya silicon hamwe nindi miti mugihe cyubushyuhe bwo hejuru kugirango itange ubucucike bwinshi, ubukana bwinshi, kwihanganira kwambara cyane hamwe nibikoresho birwanya ruswa.
1. Uburyo bwo kwitegura. Gahunda yo gutegura sisitemu ya silicon karbide isanzwe ikubiyemo intambwe ebyiri: reaction no gucumura. Mu cyiciro cyo kubyitwaramo, ifu ya karibide ya silicon ikora hamwe nindi miti yubushyuhe bwinshi kugirango ibe ifatanyirizo hamwe no gushonga hasi, nka alumina, nitride ya boron na karubone ya calcium. Izi mvange zirashobora gukora nka binders hamwe nuzuzanya kugirango zifashe kongera ubushobozi bwo guhuza hamwe nubworoherane bwifu ya silicon karbide mugihe ugabanya imyenge nubusembwa mubikoresho. Mu cyiciro cyo gucumura, ibicuruzwa bivamo ibicuruzwa byacuzwe mubushyuhe bwo hejuru kugirango bibe ibintu byiza byubutaka. Ibintu nkubushyuhe, umuvuduko nikirere gikingira bigomba kugenzurwa mugihe cyo gucumura kugirango ibikoresho bigire imikorere myiza. Ibikoresho bya silicon karbide yabonetse bifite ibimenyetso biranga ubukana bwinshi, imbaraga nyinshi, kurwanya ruswa nyinshi no kwihanganira kwambara.
2. Ibyiza. Carbide ya silicon reaction-ifite ibintu byinshi byiza cyane, bituma ikoreshwa cyane mubice byinshi. Mbere ya byose, ibikoresho bya ceramic silicon karbide bifite ubukana buhebuje ndetse birashobora no guca ibikoresho bikomeye nkibyuma. Icya kabiri, ibikoresho bya ceramic ya silicon karbide bifite imbaraga zo kwihanganira kwambara kandi birashobora gukoreshwa igihe kirekire mubihe bibi nkubushyuhe bwinshi numuvuduko mwinshi. Byongeye kandi, silicon carbide ceramic ibikoresho bifite imbaraga zo kurwanya ruswa hamwe nubushyuhe bwo hejuru, kandi birashobora gukoreshwa igihe kirekire mubidukikije byangirika nubushyuhe bwinshi.
3. Imirima yo gusaba. Carbide ya silicon ya reaction ikoreshwa mubice byinshi. Kurugero, mubikorwa byinganda, silicon carbide ceramic ibikoresho bikoreshwa cyane mubikoresho byo gukuramo, ibikoresho byo gukata no kwambara ibice. Gukomera kwayo no kwambara birwanya gukora bigira akamaro mugukata, gusya no gusya
Nibyiza byo gusya hamwe nizindi nzego. Mu nganda zikora imiti, ibikoresho bya ceramic silicon karbide birashobora gukoreshwa mugukora imiti nka acide sulfurike na acide ikomeye nka acide hydrofluoric kubera ko irwanya ruswa kandi ikagira ubushyuhe bwinshi. Mu rwego rwo mu kirere no kwirwanaho, ibikoresho bya ceramic bya silicon karbide birashobora gukoreshwa mugukora ibisasu bya misile hamwe nibikoresho byo gukingira ubushyuhe bwindege yihuta. Byongeye kandi, silicon carbide ceramic ceramic irashobora kandi gukoreshwa murwego rwibinyabuzima rwingingo zifatika hamwe nibikoresho byo kubaga amagufwa, kuko bifite biocompatibilité nziza kandi birwanya kwihanganira.
Reaction sintering silicon karbide nuburyo bwo gutegura ibikoresho byiza bya ceramic. Ifata kandi ikanda ifu ya karubide ya silicon hamwe nindi miti mugihe cyubushyuhe bwo hejuru kugirango itange ubucucike bwinshi, ubukana bwinshi, kwihanganira kwambara cyane hamwe nibikoresho birwanya ruswa. Silicon carbide ceramic ibikoresho bifite ibintu byiza, nkubukomere bwinshi, kwihanganira kwambara cyane, kurwanya ruswa nyinshi hamwe nubushyuhe bwo hejuru, bityo ikoreshwa cyane mubice byinshi nkinganda, inganda z’imiti, icyogajuru n’ingabo zirwanira hamwe n’ibinyabuzima.
