Amandla aphezulu esilicon carbide ityhubhu yeceramic SIC iintlobo ezahlukeneyo zokuxhathisa umlilo

Inkcazelo emfutshane:

I-silicon carbide ityhubhu ye-ceramic luhlobo lombhobho owenziwe nge-silicon carbide (SiC) njengenxalenye ephambili yezinto ze-ceramic. Inkqubo yokuvelisa ibandakanya ukucwangciswa komgubo, ukulungiswa kwesixhobo, ukuzaliswa komgubo, ukucinezela kwe-isostatic ebandayo, ukugqitywa kwe-core-cutting kunye nokushisa okuphezulu kwe-sintering. Lo mbhobho unoxinano oluphezulu, ukuchaneka okuphezulu komatshini kunye nesakhiwo esifanayo, esinokuhlangabezana neemfuno zeendawo ezichanekileyo, ezifana neshishini lenyukliya.
