Ukususa Ukubethela I-Silicon Carbide: 'I-Hardcore Strong' Ensimini Yokumelana Nokushisa Okuphezulu

Ezimweni zokushisa okuphezulu kokukhiqizwa kwezimboni, ukumelana nokushisa kwezinto ngokuvamile kunquma ukusebenza okuzinzile kanye nokusebenza kahle kokukhiqiza kwemishini.I-silicon carbide,njengohlobo olusha lwezinto ezihlanganisa ukusebenza nokuthembeka, kancane kancane iba yisisombululo esithandwayo sezimo zokushisa okuphezulu ngenxa yokumelana kwayo okuhle kakhulu nokushisa okuphezulu.
Ngokungafani nezinsimbi zendabuko noma izinto ezivamile ze-ceramic, inzuzo yokumelana nokushisa okuphezulu kwe-silicon carbide ivela esakhiweni sayo esiyingqayizivele sekristalu. Ama-athomu ayo angaphakathi ahlanganiswe yizibopho ze-covalent eziqinile kakhulu, akha uhlelo lwe-lattice oluzinzile olungagcina ubuqotho besakhiwo ngisho nasezindaweni ezishisa kakhulu zezinkulungwane zama-degree Celsius, futhi aluthambi kalula, aluguquki, noma luncishiswe. Lesi sici esizinzile siphula imikhawulo yezinto zendabuko emikhakheni eyahlukahlukene njengokusabela kokushisa okuphezulu, ukucubungula ukushisa, kanye nokusetshenziswa kwamandla.

Ezisetshenzisweni ezisebenzayo, ukumelana nokushisa okuphezulu kwe-silicon carbide akukhona ngokwako, kodwa kunalokho kuhambisana nezici zayo njengokumelana nokuguguleka nokumelana nokugqwala. Isibonelo, ezimweni ezifana nokwelashwa kwegesi yoketshezi lokushisa eliphezulu kanye nokuthuthwa kwensimbi encibilikisiwe, ingamelana nokugqwala kokushisa okuphezulu kanye nokuguguleka nokugqwala kwendawo, kunciphisa ukulahlekelwa kwemishini kanye nemvamisa yokugcinwa, kwehlisa ngokungaqondile izindleko zokukhiqiza nokusebenza kwebhizinisi. Lokhu kusebenza okuguquguqukayo kokumelana nokushisa okuphezulu kuye kwenza kancane kancane izinto ze-silicon carbide zaba ukwesekwa okubalulekile kokuthuthukisa ukusebenza kwemishini kanye nokwenza ngcono izinqubo zokukhiqiza egagasini lokuthuthukiswa kwezimboni.
Ngokuthuthuka okuqhubekayo kobuchwepheshe bezimboni, izidingo zokumelana nokushisa okuphezulu kwezinto nazo ziyanda njalo. I-silicon carbide, ngezinzuzo zayo zokusebenza zemvelo kanye nokuvuthwa okuqhubekayo ezinqubweni zokulungiselela, ingena kancane kancane isuka emasimini aphezulu iye ezimweni zezimboni ezivamile. Esikhathini esizayo, kungakhathaliseki ukuthi kuyizinto ezintsha embonini yamandla amasha nezinto ezintsha, noma ukuguqulwa okuluhlaza kwezimboni zendabuko, ukumelana nokushisa okuphezulu kwe-silicon carbide kuzodlala indima ebaluleke kakhulu ekuvikeleni ukusebenza kahle, ukuzinza, kanye nokuphepha komkhiqizo wezimboni.
