I-Silicon Carbide (Sic) ibonisa ukugqokwa okuvelele nokuphikiswa kokugqwala ngenxa yezakhiwo zayo ezihlukile zenyama nangamakhemikhali.
Mayelana nokumelana nokugqoka, ubulukhuni be-mohs lwe-silicon Carbide bungafinyelela ku-9.5, okwesibili kuphela kuDayimane neBoron NITride. Ukumelana kwayo ukugqokwa kulingana nezikhathi ezingama-266 zensimbi ye-manganese kanye nezikhathi eziyi-1741 ze-chromium ap ngensimbi ephezulu.
Ngokuya ngokumelana nokugqwala, i-silicon Carbide inokuqina okuphezulu kwamakhemikhali futhi kukhombisa ukumelana okuhle nama-acid aqinile, i-alkali, kanye nezixazululo kasawoti. Ngaleso sikhathi, i-Silicon Carbide ibuye ibe nokumelana okuphezulu kokugqwala kwezinsimbi ezibunjiweyo njenge-aluminium ne-zinc, futhi kuvame ukusetshenziswa kuma-rucibles nasekubumbeni embonini yensimbi.
Njengamanje, i-Silicon Carbide ehlanganiswe nesakhiwo esiphezulu futhi i-chemicalnecness yayo isetshenziswe kabanzi ezimbonini ezinjengezimayini ezinjengezimayini, zensimbi, kanye namakhemikhali, iba yindlela efanelekile yezinto ezibonakalayo ngaphansi kwezimo zokusebenza ngokweqile.
| into uqobo lwayo | gqoka ukumelana | Ukumelana nokugqwala | Ukusebenza okushisa okuphezulu | Ezomnotho (isikhathi eside) |
| I-Silicon Carbide | Phezulu kakhulu | Kuqine kakhulu | Kuhle kakhulu (<1600 ℃) | -Phezulu |
| I-Alumina ceramics | -Phezulu | -Namandla | Isilinganiso (<1200 ℃) | Okuphakathi |
| I-Metal Alloy | Okuphakathi | Buthakathaka (edinga ukunamathela) | Buthakathaka (kuthambekele ku-oxidation) | -Ngenamandla |
I-Silicon Carbide Eff-Ukuvimbela I-blockIngabe ukuhlukaniswa okubalulekile emikhiqizweni yeSilicon Carbide.Izindawo ezivimbela ukugqokwa nezintukuthelo ze-silicon Carbide zenza ukuthi zisetshenziswe kabanzi ngemishini yokugaya njengezimbiwa zebhola nezindleko zebhola ezibangelwa ukugqoka futhi ngaleyo ndlela kuncishiswe izindleko zokulungiswa komshini.
Okulandelayo ukuqhathanisa phakathi kwamabhulokhi avimbela ukugqokwa kwe-silicon kanye namanye amabhlokhi avimbela izinto zendabuko:
| Ubulukhuni futhi ugqoke ukumelana | I-Silicon Carbide Eff-Ukuvimbela I-block | Izinto Zendabuko |
| Ubulukhuni futhi ugqoke ukumelana | Ubulukhuni be-Mohts 9.5, Ukuvikelwa Okuqinile Kakhulu (Impilo Ikhuphuke Ngezikhathi Ze-5-10) | I-chromium cast iron ephezulu inobunzima obuphansi (HRC 60 ~ 65), kanti ama-alumina ceramics athambekele ekuqhekekeni kwe-brittle |
| Ukumelana nokugqwala | Ukumelana nama-acid aqinile kanye ne-alkalis | Izinsimbi zithambekele ekugqwaneni, kanti u-Alumina unokumelana ne-acid |
| Ukuqina okuphezulu kokushisa | Ukumelana Nezinga lokushisa le-1600 ℃, unxesizing emazingeni okushisa aphezulu | I-Metal ithambekele ekuguqukeni kwamazinga okushisa aphezulu, kanti u-Alumina unokumelana kwezinga lokushisa kwe-1200 ℃ kuphela |
| Ukuvuselelwa okushisayo | I-120 w / m · k, ukuncipha okusheshayo kokushisa, ukumelana okushisayo | I-Metal inokuvuka okuhle okushisayo kepha ithambekele kwi-oxidation, ngenkathi ubumba obujwayelekile bunokuphakelayo okungekho emthethweni |
| -Ongayo | Izindleko ezinde zokuphila nezindleko eziphansi | Izinsimbi zidinga ukushintshwa njalo, ubumbahema ubuthaka, kanti izindleko zesikhathi eside ziphezulu |
