Emkhakheni omkhulu wesayensi yezinto zokwakha,imikhiqizo ye-silicon carbidekancane kancane ziba "izintandokazi" zezimboni eziningi ngenxa yezakhiwo zazo eziyingqayizivele. Ikakhulukazi ukumelana kwayo okuhle kakhulu kokugqoka kwenza kukhanye ezinhlelweni ezihlukahlukene. Namuhla, ake sihlole ukugqokwa kwemikhiqizo ye-silicon carbide ndawonye.
I-silicon carbide, ngokombono wokwakheka kwamakhemikhali, iyinhlanganisela eyenziwe ngezinto ezimbili, i-silicon ne-carbon, emazingeni okushisa aphezulu. Isakhiwo sayo se-crystal siyingqayizivele kakhulu, esinikeza i-silicon carbide uchungechunge lwezakhiwo ezinhle kakhulu, futhi ubulukhuni obuphezulu buyisisekelo esiyinhloko sokumelana kwayo nokugqoka. Ukuqina kwe-silicon carbide kuphakeme kakhulu, ngokuqina kwe-Mohs okungaba ngu-9.5, kuphela ngaphansi kancane kunedayimane elinzima kakhulu ngokwemvelo. Ubulukhuni obunjalo obuphakeme busho ukuthi ingamelana ngempumelelo nokungqubuzana nokuguga kwangaphandle, futhi isalondoloze ubuqotho bayo nokuzinza kokusebenza lapho ibhekene nezimo ezihlukahlukene zokusetshenziswa ezinonya.
Ngokombono we-microscopic, i-microstructure yemikhiqizo ye-silicon carbide iminyene kakhulu. Cishe awekho ama-pores amakhulu noma amaphutha ngaphakathi, okwenza kungabi lula ekulimaleni kwesakhiwo kanye nokuhlukaniswa kwempahla uma ibhekene nokungqubuzana. Kufana nenqaba eqinile, enezindonga ezixhunywe ngokuqinile okunzima ukuthi izitha zibhodloke kuzo. Uma kunokungqubuzana phakathi kwezinto zangaphandle kanye nobuso be-silicon carbide, ukwakheka kwayo okuminyene kungahlakaza amandla okungqubuzana, kugweme ukugqokwa kwendawo okubangelwa ukugxila kwengcindezi, futhi kuthuthukise kakhulu ukumelana nokugqoka okuphelele.
Ukuzinza kwamakhemikhali nakho kuyisikhali esikhulu sokumelana nokugqokwa kwe-silicon carbide. Ezimweni eziningi ezisebenzayo zokusetshenziswa, izinto zokwakha azidingeki nje ukumelana nokuguga kwemishini, kodwa zingase zibhekane nokuguguleka kwamakhemikhali. I-Silicon carbide inokuqina okuhle kakhulu kwamakhemikhali, futhi ayithambekele ekuphenduleni kwamakhemikhali nezinye izinto ezingabangela ukonakala kokusebenza, noma ngabe kusendaweni yamakhemikhali ebolayo noma ngaphansi kwezimo ezimbi kakhulu ezifana namazinga okushisa aphezulu. Ngisho nangaphansi kwezimo ezinzima zokushisa okuphezulu nokugqwala isikhathi eside, imikhiqizo ye-silicon carbide isengakwazi ukugcina ubulukhuni bayo nobuqotho besakhiwo, futhi iqhubeke nokubonisa ukumelana nokugqokwa okuhle.
Ekusetshenzisweni okungokoqobo, izinzuzo zokumelana nokugqoka kwemikhiqizo ye-silicon carbide ziboniswa ngokugcwele. Embonini yezimayini, i-silicon carbide ivame ukusetshenziselwa ukwenza amathuluzi okumba anjengezinsimbi zokubhola, amathuluzi okusika, njll. Lawa mathuluzi adinga ukumelana nokucindezeleka okukhulu kwemishini kanye nokungqubuzana okuvamile ngesikhathi sokumba ama-ores aqinile, kuyilapho i-silicon carbide, enokumelana nokuguga okuphezulu, inganweba kakhulu impilo yesevisi yamathuluzi, inciphise imvamisa yokushintshwa kwamathuluzi, kanye nezindleko eziphansi zokumba. I-Silicon carbide nayo isetshenziswe kabanzi ezingxenyeni zokuvala, ama-bearings, nezinye izingxenye zemishini yezimboni. Inganciphisa ngempumelelo ukuguga kwalezi zingxenye ngesikhathi sokusebenza ngesivinini esikhulu kanye nokungqubuzana okuvamile, ithuthukise ukusebenza kahle nokusebenza kahle kwemishini, futhi yehlise izindleko zokuyilungisa.
Ukumelana nokugqokwa kwemikhiqizo ye-silicon carbide kunqunywa ukwakheka kwayo kwamakhemikhali okuhlukile, ukwakheka kwekristalu, nezici ezincane kakhulu. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokucwaninga okujulile nge-silicon carbide, sikholelwa ukuthi imikhiqizo ye-silicon carbide izosetshenziswa emikhakheni eminingi, ilethe amathuba amasha nezinguquko ekuthuthukisweni kwezimboni ezihlukahlukene.
