I-Silicon Carbide (i-SIC) ibonisa impahla enxibe impahla enxibelelekileyo kunye nokunganyangeki ngenxa yemali eyahlukileyo yomzimba kunye neekhemikhali.
Ngokuphathelelene nokunganyangeki, ubunzima be-mohs ye-silicon carbide bunokufikelela kwi-9.5, yesibini kuphela kwidayimani kunye ne-boron nitride. Ukunganyangeki kwawo kulingana namaxesha angama-266 ama-266 amaXesha aseManganese kunye ne-1741 amaxesha e-chromiya atyhidiweyo.
Ngokuphathelele kokunganyangeki kwe-corrosion, i-silicon carbide inozinzo oluphezulu lwamachiza kwaye ibonise ukumelana ngokugqwesileyo kwii-AIDs ezomeleleyo, ialkalis, kunye nezisombululo zetyuwa. Ngeli xesha, i-silicon carbide ikwanokunganyangeki okuphezulu kwiintsimbi ezifana ne-aluminium kunye ne-zinc, kwaye iqhele ukusetyenziswa kwishishini le-metselwargalgallogical.
Okwangoku, i-silicon carbide idityaniswe nesakhiwo se-superhard kunye ne-suerturd yekhemikhali isetyenziswe ngokubanzi kumashishini anjengokokudlala, intsimbi, kunye neekhemikhali, ukuba yinto efanelekileyo yokukhetha phantsi kweemeko ezifanelekileyo zomsebenzi.
| Izixhobo | nxiba ukuxhathisa | Ukunganyangeki | Ukusebenza kobushushu obuphezulu | Izoqoqosho (ixesha elide) |
| I-Silicon carbide | Kakhulu | Yomelele kakhulu | Ilungile (<1600 ℃) | Phezulu |
| I-Aluminii Ceramics | Phezulu | Yomelele | Umndilili (<1200 ℃) | Phakathi |
| Isabelo sensimbi | Phakathi | Ubuthathaka (efuna ukuphikisana) | Buthathaka (thambele kwi-oxidation) | Ubuthathaka |
Ibhloko ye-Silicon CarbideNgaba ulusu olubalulekileyo kwimveliso ye-selicon ye-selicon carbide.I-Interpotions kunye ne-corrosion kunye ne-corrosion kunye ne-corrosion-carbide ye-silicon carbide yenza ukuba isetyenziswe ngokubanzi kwizixhobo ze-GARDE ezifana nokunxiba kwaye zinciphise iindleko zokulungisa umatshini.
Oku kulandelayo kukuthelekisa phakathi kwe-Silicon Carbide i-carbide edinwe-engahambelaniyo nezinye izinto zesiqhelo zokunxiba:
| Ubunzima kwaye banxibe ukumelana | Ibhloko ye-Silicon Carbide | Izinto zendabuko |
| Ubunzima kwaye banxibe ukumelana | I-MOHS Hard 9.5, nxiba kakhulu ukuxhaphaza (ubomi buyekile ngamaxesha angama-5 ukuya kweli-7) | I-chromium ephezulu yaphosa i-iron inobuqili obuphantsi (HRC 60 ~ 65), kunye ne-Aluminics Ceramic bakrwelelwe ukuqhekeka kweBrittle |
| Ukunganyangeki | Ukunganyangeki kwi-asidi eyomeleleyo kunye ne-alkalis | Izinyithi zithambekele ekubonakaleni, ngelixa i-Alumna inomyinge ophakathi |
| Uzinzo lobushushu obuphezulu | Ukunyangwa kobushushu kwe-1600 ℃, ukungazithembi kumaqondo obushushu aphezulu | Isinyithi sithambekele kwingxaki kubushushu obuphezulu, ngelixa i-Alumna inobushushu be-1200 kuphela ℃ |
| Ukuqhubela phambili kwe-thermal | I-120 W / M · k, ukubekwa kwe-sub yokutshisa okukhawulezileyo, ukungavisisani kwe-thermal | Isinyithi sinengxaki yokuqhubela phambili kwe-thermal kodwa thambekele kwi-oxidation, ngelixa i-ceramic eqhelekileyo iphumelele |
| Ezoqoqosho | Ixesha elide le-Lindespan kunye neendleko eziphantsi kakhulu | Izinyithi zifuna ukutshintshwa rhoqo, i-ceramics ibuthathaka, kwaye iindleko zexesha elide ziphezulu |
Ixesha lokuphumla: Mar-18 ukuya kwi-2025
