Isingeniso kubuchwepheshe obusha be-posting techning for ceramics athuthukile

Ubuchwepheshe obusha wesono okusheshayo kwama-ceramics athuthukile aluhlobo olusha lobuchwepheshe bokulungiswa kwezinto ze-ceramic, olunezinzuzo zesivinini esisheshayo se-sontering, ama-destity amahle kakhulu wezono. Lezi zinqubo ezintsha zingathuthukisa kakhulu izimo ze - ceramic ze-ceramic, njengokuzazisa okuphezulu kokushisa okuphezulu ( SHS) , i-spark plasma sonoing ( ama - sps) , njll.

Okokuqala, ubuchwepheshe obusha wesono okusheshayo kwama-ceramics athuthukile abonakala ngejubane le-sontering esheshayo. Izindlela zokulungiselela ezibonakalayo zendabuko zivame ukudinga inqubo ende yesono, kepha ubuchwepheshe obusha besono okusheshayo bungaqedela inqubo efihlekile ngesikhathi esifushane. Leli jubane le-sontering elisheshayo lingathuthukisa kakhulu ukusebenza kahle kokukhiqiza, umjikelezo wokukhiqiza wefushise futhi wehlise izindleko zokukhiqiza.

Okwesibili, ubuchwepheshe obusha wesono okusheshayo we-teramics technical bungalungiselela izinto zobumba zobumba ezinama-density aphezulu. Izindlela ze-sontering zendabuko zithambekele ekukhiqizeni ama-pores kanye namaphutha, okuholela ekunciphiseni amandla futhi kugqoke ukumelana kwezinto zokwakha ubumba. Ubuchwepheshe obusha besono okusheshayo, ngokulawula izinga lokushisa lesono nesikhathi, bungenza izakhi ze-ceramic zifezeke ubukhulu futhi zithuthukise izakhiwo zalo zemishini nokugqoka.

Ngaphezu kwalokho, ubuchwepheshe obusha wesono okusheshayo kwama-ceramics athuthukile nawo unezakhiwo ezinhle kakhulu zemishini. Izinto ezijwayelekile ze-ceramic zivame ukuvezwa yi-brittleness kanye namandla aphansi, anciphisa ukusetshenziswa kwawo okubanzi kuzinhlelo zokusebenza zobunjiniyela. Ubuchwepheshe obusha wesono okusheshayo bungapheka izinto zobumba zobumba ngamandla aphezulu kanye nobunzima, okwenza kube namathemba wohlelo lokusebenza olubanzi ezintweni zokwakha, izinto ezivimbela ukugqoka kanye nezinye izinkambu.

Ekuphetheni, ubuchwepheshe obusha besono okusheshayo kwama-ceramics athuthukile ahlinzeka ngendlela ephumelelayo, ezomnotho futhi enokwenzeka yokulungiselela izinto zokwenziwa ze-ceramic ngokusebenzisa isivinini esisheshayo se-sontering desicing, indawo ephezulu ye-sontering. Ukusetshenziswa kwalobu buchwepheshe kuzothuthukisa ukuthuthukiswa kwezinto zokwenziwa kwe-ceramic, kwandisa uhla lwayo lwesicelo emikhakheni ehlukahlukene, futhi kunikeze amathuba amasha entuthuko yezinkambu zobunjiniyela.
