I-silicon carbide ceramics: Umdlali oguquguqukayo kwibala lemizi-mveliso

Kusapho lwesayensi yezinto, ii-silicon carbide ceramics ziye zavela ngokuthe ngcembe "njengemveliso eshushu" kwiindawo ezininzi zoshishino ngenxa yeempawu zazo ezizodwa. Namhlanje, masingene kwihlabathi lei-silicon carbide ceramicsubone apho igqwesa khona.
I-Aerospace: Ukusukela ukuKhanya kunye nokusebenza okuphezulu
Umzi-mveliso we-aerospace uneemfuno eziphezulu kakhulu zemathiriyeli, ezingafuneki nje ukuba zikhaphukhaphu ngokwaneleyo ukuze zinciphise ubunzima benqwelomoya, kodwa zibe namandla abalaseleyo kunye nokumelana nobushushu obuphezulu. Uxinaniso olusezantsi kunye neempawu eziphezulu zokuqina ezikhethekileyo zeeseramics zesilicon carbide zizenza zibe yimathiriyeli efanelekileyo yokwenza amacandelo enjini yenqwelomoya kunye namalungu olwakhiwo lwenqwelomoya. Khawucinge ukuba kwindawo yokushisa ephezulu kunye noxinzelelo oluphezulu lwe-injini yendiza, ii-turbine blades kunye nezixhobo zegumbi lokutsha ezenziwe nge-silicon carbide ceramics azikwazi nje ukumelana namaqondo okushisa aphezulu, kodwa zinokunceda injini iphucule ukusebenza kakuhle kunye nokunciphisa ukusetyenziswa kwamandla kunye nobunzima obulula. Ngaba ayimangalisi? Ngaphezu koko, ukuzinza kwayo kwe-thermal okugqwesileyo kunokuqinisekisa ukuba amacandelo akayi kuguqulwa okanye wonakaliswe ngenxa yokutshintsha kweqondo lokushisa xa inqwelo-moya ivelisa ubushushu obukhulu ngexesha lokuhamba ngesantya esiphezulu, inika ukhuseleko lokhuseleko lokubhabha.

Ukwenziwa kweSemiconductor: Inkxaso engundoqo kwiiNkqubo eziChanekileyo
Ukwenziwa kweSemiconductor yintsimi efuna phantse ukuchaneka okungqongqo kunye nokusebenza kwezinto eziphathekayo. Iiceramics ze-silicon carbide zidlala indima ebaluleke kakhulu kwizixhobo ze-semiconductor ngenxa yobunzima bazo obuphezulu, i-coefficient yokwandisa i-thermal, kunye nokuzinza okugqwesileyo kweekhemikhali. Kwiinkqubo ezingundoqo ezifana ne-photolithography kunye ne-etching, abathwali be-wafer kunye nokulungiswa okuchanekileyo okwenziwe nge-silicon carbide ceramics kunokuqinisekisa ukubeka okuchanekileyo okuphezulu kwee-silicone wafers ngexesha lokucubungula, ukuqinisekisa ukuchaneka kokwenziwa kwe-chip. Kwangaxeshanye, ukuxhathisa umhlwa kwiirejenti zeekhemikhali ezahlukeneyo kunye neplasma kwandisa kakhulu ubomi benkonzo yezixhobo, kunciphisa iindleko zemveliso, kwaye kukhuthaze uphuhliso oluqhubekayo lwetekhnoloji ye-semiconductor ukuya kubukhulu obuncinci kunye nokusebenza okuphezulu.
Icandelo lezaMandla: Ukujongana nemingeni yobushushu obuphezulu kunye nomhlwa
Kwishishini lamandla, nokuba ngamandla emveli ashushu, ishishini lemichiza, okanye amandla enyukliya asakhulayo kunye nelanga, zonke zijongana neemeko zokusebenza ezinzima ezifana nobushushu obuphezulu kunye nomhlwa. Kwiibhoyila zokuvelisa amandla okushisa, i-nozzles yokutshisa kunye nezixhobo zokushisa ubushushu ezenziwe nge-silicon carbide ceramics zinokuxhathisa ukukhukuliseka kwamadangatye obushushu obuphezulu kunye neegesi ezitshabalalisayo, ukuphucula ukusebenza kakuhle kunye nokuthembeka kwezixhobo; Kwinkalo yamandla enyukliya, iiseramics zesilicon carbide zisetyenziswa ekufakeni amafutha, imathiriyeli yesakhiwo, njl.njl. kwizixhobo zenyukliya ngenxa yokumelana nobushushu obuphezulu kunye nokuxhathisa kwimitha, iqinisekisa inkqubela ekhuselekileyo nezinzileyo yereactors zenyukliya; Kwishishini le-solar photovoltaic, i-silicon carbide ceramics ingasetyenziselwa ukwenza izixhobo ezithwala umthwalo kwiziko lobushushu obuphezulu, ukuxhasa ngokuzinzileyo ukusetyenzwa kwezixhobo ezinjengee-silicon wafers kwindawo ezinobushushu obuphezulu, kunye nokunceda ekuphuculeni ukusebenza kakuhle koguqulo lwamandla elanga.
Ukucutshungulwa komatshini: isiqinisekiso sokumelana nokunxiba kunye nokuchaneka okuphezulu
Kwintsimi yokulungiswa komatshini, ubunzima obuphezulu kunye nokumelana nokunxiba kwe-silicon carbide ceramics kwenza kube yinto ekumgangatho ophezulu wokuvelisa izixhobo zokusika, izixhobo zokugaya, iibheringi kunye nezinye izinto. Xa sisebenzisa izixhobo zokusika i-silicon carbide ceramic ukusika izinto zetsimbi, zinokujamelana ngokulula nemikhosi yokusika ephezulu, igcine ubukhali beblade, iphucule kakhulu ukusebenza kakuhle kunye nokuchaneka, ukunciphisa ukunxiba kwesixhobo kunye nokuphindaphinda indawo. I-silicon carbide iibheringi ze-ceramic, kunye ne-coefficient ephantsi ye-friction kunye nokuqina okulungileyo, inokusebenza ngokuzinzile, ukunciphisa ukusetyenziswa kwamandla, kunye nokwandisa ubomi benkonzo ye-high-speed ejikelezayo izixhobo zomatshini, ukubonelela ngenkxaso eqinile yophuhliso olusebenzayo loshishino lokuvelisa oomatshini.
I-Silicon carbide ceramics, kunye nokusebenza kwayo okugqwesileyo, ifumene inqanaba labo kwiinkalo ezininzi zoshishino, kunye nenkqubela phambili eqhubekayo yetekhnoloji, ithemba lokusetyenziswa kwayo liya kuba libanzi, lifake amandla amatsha kuphuhliso lwamashishini ahlukeneyo.
