Ishubhu Lokuvikela le-RSiC
Ulwazi Lomkhiqizo
Amashubhu Okuvikela i-Silicon Carbideyizingxenye ezikhethekile zeshubhu ezenziwe ngezinto ze-silicon carbide (SiC) ceramic, ezisetshenziswa kakhulu ukuvikela izinto ezibucayi (njenge-thermocouples) noma njengezingxenye eziyinhloko emishinini yokuthutha uketshezi olushisa kakhulu kanye neyokushintshana kokushisa.
Imikhiqizo yethu ikhiqizwa kakhulu kusetshenziswa izinqubo ezintathu:Ukushisa kokusabela (RBSiC), Ukuvuselelwa kabusha (RSiC), i-silicon carbide eboshwe yi-silicon nitride (NSiC)
1. Amashubhu okuvikela e-RSiC
Kusetshenziswa i-SiC micro powder emsulwa kakhulu njengezinto zokusetshenziswa, ishiswa emazingeni okushisa aphezulu (2000–2200℃). Isakhiwo esiqinile sakhiwa ngokuhlanganiswa kabusha kwekristalu kanye nokuhlanganiswa kwemingcele yezinhlamvu zezinhlayiya zeSiC ngokwazo, ngaphandle kwesigaba esengeziwe sokubopha.
Izici Eziyinhloko:
Ukumelana Okumangalisayo Nokushisa Okuphezulu:Izinga lokushisa lokusebenza lesikhathi eside kufika ku-1600℃, ukumelana kwesikhashana ku-1800℃, okwenza kube ngcono kakhulu maqondana nokumelana nokushisa okuphezulu phakathi kwezinhlobo ezintathu, ezifanele ama-oven ashisa kakhulu (njenge-oven ye-ceramic sintering kanye nama-oven e-metallurgical blast).
Ukumelana Okuhle Kakhulu Noku-Oxidation:Emazingeni okushisa aphezulu, ifilimu elivikelayo le-SiO₂ elijiyile liyakheka ebusweni, livimbele ukungcoliswa okwengeziwe kwe-SiC yangaphakathi, okubonisa ukuzinza okuphezulu kakhulu ezindaweni ezingcolisa umoya.
Isilinganiso Esiphansi Kakhulu Sokwanda Kokushisa:I-coefficient yokwanda kokushisa ingu-4.5 × 10⁻⁶ /℃ kuphela, enikeza ukumelana okuhle kokushaqeka kokushisa, yize iphansi kancane kuneye-silicon carbide eboshwe yi-silicon nitride.
Ubulukhuni obuphezulu kanye nokumelana nokuguguleka okuphezulu:Njengoba i-Mohs ilukhuni cishe ku-9, ikhombisa ukumelana okuvelele nokuguguleka kwezinto, okwenza ifanelekele ukugeleza komoya okushisa okuphezulu kanye nezimo zokugeleza koketshezi eziqukethe izinhlayiya eziqinile.
Ukuqina kwamakhemikhali okuqinile:Ayimelani nama-asidi aqinile nama-alkali, futhi ayisabelani nezinsimbi eziningi ezincibilikisiwe.
Imikhawulo:
Izinga lokushisa eliphakeme kakhulu lokushiswa, okuholela ekubhobozeni okuphezulu kancane (cishe u-5%–8%) kanye nokumelana nokucindezela okuphezulu okubuthakathaka kancane; ukuphuka okuphezulu kokushisa kwegumbi, kanye nokumelana nokushaya akukuhle njenge-silicon carbide eboshwe yi-silicon nitride.
2. Amashubhu okuvikela i-RBSiC
Kusetshenziswa izinhlayiya ze-SiC kanye ne-graphite njengezinto zokusetshenziswa, izinto zidlula enkambisweni yokungena kwe-silicon. I-silicon ewuketshezi ingena futhi igcwalise ama-pores, isabela ne-graphite ukuze yakhe isigaba esisha se-SiC, ekugcineni idale isakhiwo esihlanganisiwe se-"SiC framework + free silicon".
Izici Eziyinhloko:
Ukuminyana okuphezulu kanye nokuvuleka okuphansi:I-silicon yamahhala igcwalisa izimbobo, inciphisa izimbobo zibe ngaphansi kuka-1%, okuholela ekuphepheni komoya okuhle kakhulu kanye nokumelana nokucindezela okuphezulu, okufanelekela ukucindezela okuphezulu kanye nokushisa okuphezulu
izimo zokuvala (njengezitofu ezishisa ukucindezela).
Izakhiwo ezinhle zemishini:Amandla okugobeka kwezinga lokushisa legumbi angu-250–400MPa, ukuqina kokuphuka okuphezulu, kanye nokumelana nokushayisana okuphakeme kune-silicon carbide ephinde yasetshenziswa.
Ukumelana nokushisa okuphezulu okumaphakathi:Izinga lokushisa lokusebenza kwesikhathi eside lingu-1200℃. Ngaphezu kuka-1350℃, i-silicon yamahhala iyathamba, okuholela ekunciphiseni amandla futhi kunciphise ukusebenza kwezinga lokushisa eliphezulu.
Ukucutshungulwa okuhle:Ukuba khona kwe-silicon yamahhala kunciphisa ubuthakathaka bezinto ezibonakalayo, okwenza kube lula ukuzisebenzisa zibe izimo eziyinkimbinkimbi, okuholela ezindleleni zokukhiqiza eziphansi kakhulu.
Imikhawulo:
Ukusebenza kwezinga lokushisa eliphezulu kunqunyelwe yi-silicon yamahhala, okwenza ingafaneleki ukusebenza isikhathi eside ngaphezu kuka-1350℃; i-silicon yamahhala isabela kalula kuma-alkali aqinile, i-aluminium encibilikisiwe, njll., okuholela ebangeni elincane lokumelana nokugqwala.
3. Ishubhu lokuvikela le-NSiSC
Kuyizinto ezihlanganisiwe ezakhiwe ngokuxhumanisa izinhlayiya ze-SiC ngokuqinile ku-silicon carbide matrix ngokukhiqiza i-Si₃N₄ njengesigaba sokubopha nge-nitriding reaction.
Izici Eziyinhloko:
1. Ukumelana Nokushaqeka Okuphezulu Kokushisa:I-coefficient ephansi yokwanda kokushisa kanye nokuqina okuphezulu kwesigaba esihlanganisiwe se-Si₃N₄ kuvumela ithubhu elivikelayo ukuthi likwazi ukumelana nokushisa okusheshayo nokupholisa okungaphezu kuka-1000℃ ngaphandle kokuqhekeka ngenxa yokushintsha kwezinga lokushisa okungazelelwe, okwenza lifanelekele izimo zokusebenza ezinokushintshashintsha kwezinga lokushisa okuvamile.
2. Ukumelana Okuhle Kakhulu Kokugqwala:Iqinile kakhulu ngokumelene nama-asidi aqinile, ama-alkali aqinile, izinsimbi ezincibilikisiwe (njenge-aluminium nethusi), kanye nosawoti oncibilikisiwe, okwenza ifaneleke kakhulu ezindaweni ezigqwalisayo ezimbonini zamakhemikhali nezensimbi.
3. Amandla Aphezulu Okusebenza Kwemishini:Amandla okuguquguquka kwezinga lokushisa legumbi afinyelela ku-300–500 MPa, ngokugcinwa kwamandla okungcono emazingeni okushisa aphezulu kunemikhiqizo ye-SiC emsulwa, kanye nokumelana okunamandla komthelela.
4. Izinga Lokushisa Elisebenzayo:Izinga lokushisa lokusebenza lesikhathi eside lingu-1350℃, ikhono lokumelana lesikhathi esifushane kufika ku-1500℃.
5. Ukuvikela Okuhle:Igcina ukuvikela okuhle kukagesi ngisho noma amazinga okushisa aphezulu, ivimbela ukuphazamiseka kwesignali ye-thermocouple.
Imikhawulo:
Ukumelana nokubola kwe-oxidation kuphansi kancane kune-silicon carbide ephinde yasetshenziswa; ukusetshenziswa kwesikhathi eside ezindaweni ezinamandla zokubola kwe-oxidation kungaholela ekuqhekekeni kwezingqimba ze-oxide ebusweni.
