I-Silicon Carbide (i-SIC) ye-ceramicsbaziwa ngamandla abo angenakuthelekiswa nanto, ukumelana nobushushu, kunye nokuqina. Ezi propati zizenza zilungele ukusetyenziswa kwiindawo ezinzima, ezinje ngeenjini ze-aerospace okanye zomatshini wezamashishini. Kodwa zinjani na ezi zinto zibalulekileyo? Masiphelise inkqubo yenyathelo ngenyathelo.
1.Row ukulungiselela izinto
Konke kuqalisa ngokucocekileyo-gelity ye-carbicon carbide. Cinga ngale nto njenge "umgubo" ngokubhaka i-curaramic "ikhekhe eliyi-celuitives.
I-2. Ukulungisa i-ceramic
Umgubo ke uguqulwe ube yifom enqabileyo. Iindlela ezimbini eziqhelekileyo zisetyenzisiwe:
Ukucinezela: I-powder inyanzelwa kwimo ethile usebenzisa uxinzelelo oluphezulu, olufana nokwenza ikhephu kwibhola yekhephu.
Inaliti yokubumba: Umgubo uxutywe ne-binder yethutyana (njenge-wax) ukwenza umxube onjenge-inhlama, oxhonywe ekubunjweni ngemilo enzima.
Okwangoku, lo mbandela usabuthathaka-njenge-Skroptihed yesanti eyomileyo-kwaye kufuneka "abhaki" womelele.
3. Inkqubo yokutya
Kulapho umlingo wenzeka khona. I-ceramic eyenziwe nge-ceramic ishushu kwisitya esikhethekileyo kumaqondo obushushu aphezulu kakhulu (rhoqo ngaphezulu kwe-1,800 ° C). Ngexesha lokuthunga, izinto ezimbini eziphambili:
Amasuntswana ebodwa: I-selicon ye-carbide ikhula, isuse izithuba kwaye isebenze isakhiwo esiqinileyo.
I-Onsoctions Umsebenzi: Iikhawuntari ezidityanisiweyo zinyibilike kancinci, zenza "ibhulorho" phakathi kwamasuntswana ukuphucula ubunzima.
Imo engqongileyo ngaphakathi kwiziko lilawulwa ngononophelo - ngamanye amaxesha lizaliswe ziigesi-ukuthintela ukuphendula okungafunekiyo.
4. Ukugqiba ukuchukumisa
Emva kokuqina, i-ceramic isenokwenza unyango olongezelelekileyo lokuphucula intsebenzo yalo:
Ukushicilelwa: Izicelo ezifuna indawo egudileyo (umzekelo, amatywina okanye ebheriweyo).
I-COATE: Umaleko okhuselayo obambeleyo (njenge-silicon nitride) ongongezwa ekukhuliseni ukunyangwa.
I-Maching: Ukunqunyulwa ngokuchanekileyo okanye ukuqhuba ukufezekisa ubukhulu bokugqibela.
Kutheni le nkqubo ibaluleke
Imfihlo yamandla ka-Silicon Carbide ilele indlela i-atom yenziwa ngayo ngexesha lokuqina. Inkqubo yobushushu obuphezulu ibonisa inethiwekhi ye-Silicon ye-silicon-carbon, engaxhathisi ubushushu, ukususwa kunye noxinzelelo lomzimba. Izongezo kunye nolawulo lobushushu oluchanekileyo luqinisekisa ukuba imveliso yokugqibela ayinzima nje kodwa inzima ngokwaneleyo ukuba ixhathise ukuqhekeka.
Umfanekiso omkhulu
Ukusuka kwii-turbines ezisikiweyo kwiinkqubo zolawulo longcoliseko, i-silicon carbide ceramics idlala indima ebalulekileyo kwitekhnoloji yale mihla. Ngelixa inkqubo yokwenziwa ihamba nzima, lolu lungelo lononophelo lwezenzululwazi nobunjineli oguqula umgubo olulula ube kwimeko ekwaziyo ukuba neyona meko ibalaseleyo.
Njengoko inkqubela phambili yophando, iindlela ezintsha-njengokuprinta ze-ceramics - ziyavela, zithembisa ngokusebenzisa ngakumbi le mpahla ingako.
