Silicon carbide e sintering e nang le karabelo ke mokhoa oa ho lokisa thepa ea letsopa e sebetsang hantle haholo. E arabela le ho hatella phofo ea silicon carbide le lik'hemik'hale tse ling tlas'a maemo a mocheso o phahameng ho hlahisa boima bo phahameng, ho thatafala ho phahameng, ho hanyetsa ho tsofala ho phahameng le thepa e hanyetsang ho bola ho phahameng.
1. Mokhoa oa ho lokisa. Ts'ebetso ea ho lokisa silicon carbide e sebetsang ka mokhoa o arabelang hangata e kenyelletsa mehato e 'meli: karabelo le ho sinter. Mokhahlelong oa karabelo, phofo ea silicon carbide e arabela le lik'hemik'hale tse ling mochesong o phahameng ho etsa metsoako e nang le lintlha tse tlase tsa ho qhibiliha, joalo ka alumina, boron nitride le calcium carbonate. Metsoako ena e ka sebetsa e le li-binder le li-filler ho thusa ho eketsa bokhoni ba ho kopanya le ho phalla ha phofo ea silicon carbide ha e ntse e fokotsa masoba le liphoso thepa. Mokhahlelong oa ho sinter, sehlahisoa sa karabelo se sintered mochesong o phahameng ho etsa thepa e teteaneng ea ceramic. Lintho tse kang mocheso, khatello le sepakapaka se sireletsang li hloka ho laoloa ts'ebetsong ea ho sinter ho netefatsa hore thepa e na le ts'ebetso e ntle. Thepa ea silicon carbide ea ceramic e fumanoeng e na le litšobotsi tsa ho ba thata haholo, matla a phahameng, ho hanyetsa ho hoholo ha mafome le ho hanyetsa ho hoholo ha ho robeha.
2. Thepa. Carbide ea silicon e nang le karabelo e na le thepa e mengata e ntle haholo, e leng se etsang hore e sebelisoe haholo masimong a mangata. Ntlha ea pele, thepa ea ceramic ea silicon carbide e na le bothata bo phahameng haholo 'me e ka ba ea seha thepa e thata joalo ka tšepe. Ea bobeli, thepa ea ceramic ea silicon carbide e na le khanyetso e ntle ea ho tsofala 'me e ka sebelisoa nako e telele tlas'a maemo a thata joalo ka mocheso o phahameng le khatello e phahameng. Ho phaella moo, thepa ea ceramic ea silicon carbide e na le khanyetso e phahameng ea ho tsofala le botsitso bo phahameng ba mocheso, 'me e ka sebelisoa nako e telele libakeng tse senyang le mochesong o phahameng.
3. Masimo a tshebediso. Carbide ya silicon e sintered e sebediswa masimong a mangata. Mohlala, indastering ya tlhahiso, thepa ya ceramic ya silicon carbide e sebediswa haholo di-abrasives, disebedisweng tsa ho seha le dikarolong tsa ho tsofala. Bothata ba yona bo phahameng le ho hanyetsa ho tsofala di etsa hore e be molemo bakeng sa ho seha, ho sila le ho sila.
E loketse ho bentša le masimo a mang. Indastering ea lik'hemik'hale, lisebelisoa tsa ceramic tsa silicon carbide li ka sebelisoa ho hlahisa lik'hemik'hale tse kang sulfuric acid le li-acid tse matla tse kang hydrofluoric acid ka lebaka la ho hanyetsa ho hoholo ha mafome le botsitso bo phahameng ba mocheso. Lefapheng la lifofane le tšireletso, lisebelisoa tsa ceramic tsa silicon carbide li ka sebelisoa ho etsa likheo tsa limisaele le lisebelisoa tsa tšireletso ea mocheso bakeng sa lifofane tse lebelo le phahameng. Ho phaella moo, lisebelisoa tsa ceramic tsa silicon carbide li ka boela tsa sebelisoa lefapheng la bongaka la manonyello a maiketsetso le lisebelisoa tsa ho buoa tsa masapo, hobane li na le biocompatibility e ntle le ho hanyetsa ho tsofala.
Silicon carbide e sintering ka lebaka la karabelo ke mokhoa oa ho lokisa thepa ea ceramic e sebetsang hantle haholo. E arabela le ho hatella phofo ea silicon carbide le lik'hemik'hale tse ling tlas'a maemo a mocheso o phahameng ho hlahisa thepa e nang le boima bo phahameng, boima bo phahameng, ho hanyetsa ho tsofala ho phahameng le ho hanyetsa ho tsofala ho phahameng. Lisebelisoa tsa silicon carbide tsa ceramic li na le thepa e ntle, joalo ka boima bo phahameng, ho hanyetsa ho tsofala ho phahameng, ho hanyetsa ho tsofala ho phahameng le botsitso ba mocheso o phahameng, kahoo e sebelisoa haholo masimong a mangata a kang tlhahiso, indasteri ea lik'hemik'hale, masimo a lifofane le a tšireletso le masimong a bongaka.
