Lumela, metsoalle!Re setsebibaetsi ba likarolo tsa tšepe tse phofshoana Chaena. Re na le tse ngataphofo ea metallurgy sintering ea likarolo. Joaloka moetsi oa metallurgy oa phofo, ke tla u joetsa hore na ho etsoa joang ka metallurgy ea phofo!
Sintering process ka phofo ea metallurgye fetoha letoto la liphetoho tsa 'mele le tsa lik'hemik'hale, tse kang metsi kapa mouoane oa tlhaho kapa ho fetoha mouoane, ho hloekisa khase ea adsorption, ho felisa khatello ea kelello, phokotso ea phofshoana ea phofshoana, ho falla ha thepa ea intergranular, recrystallization le kholo ea lijo-thollo, kahoo ho etsa hore sebopeho sa kristale pakeng tsa likaroloana se eketsehe, pore e fokotseha kapa e nyamela. Ha karolo ea mokelikeli e hlaha, ho qhibiliha le pula ea karolo e tiileng le eona e tla etsahala. Ts'ebetso ena ha e na meeli e hlakileng, empa e kopana ebile e susumetsana. Ho phaella ho tse ling tse sintering ka metallurgy, karabelo ea lihlahisoa tsohle tse entsoeng ka phofo metallurgy e rarahane. Ka 1942, Jeremane GF Schutig o ile a sebelisa mekhoa ea ho etsa lipatlisiso 'meleng le lik'hemik'hale ho lekanya tšusumetso ea mocheso oa sintering ka matla a electromotive, solubility, density, microstructure, thepa ea mechine ea' mele o sintered, 'me a fumana hore sintering ke mokhoa o rarahaneng haholo. Ka 1949, GCKuczynski oa United States o ile a ithuta ho chesoa ha libolo tsa tšepe le lipoleiti tsa tšepe 'me a lumela hore ho falla ha thepa nakong ea sintering ho ne ho etsoa haholo-holo ka ho hasana. Mosebetsi oa bona o ile oa sutumelletsa thuto ea khopolo ea sintering sethaleng se secha. Boholo ba mosebetsi o latelang oa lipatlisiso o lebisitse tlhokomelo ea mochine oa ho falla ha thepa nakong ea sintering.
Ka kakaretso ho lumeloa hore ho na le mekhoa e mehlano ea ho falla ha thepa nakong ea sintering: ho phalla ha viscous kapa polasetiki, mouoane le condensation, phallo ea molumo, phallo ea moeli oa lijo-thollo, le ho phalla holimo. Ha likaroloana tse peli tse chitja tse hokahaneng li hokahane, kholo ea radius ea molala oa X e ka amana le nako ea sintering ka tsela e latelang:
Sintering process Sintering e tlameha ho etsoa ka seboping sa sintering se nang le sepakapaka se sireletsang ho qoba oxidation ea 'mele o sintered kapa karabelo e mpe ea lik'hemik'hale. Ho na le mefuta e mengata ea libopi tsa sintering, tse ka sebelisoang e le mehloli ea mocheso joalo ka khase ea tlhaho, khase, oli le motlakase. Sebōpi sa ho futhumatsa motlakase se na le chelete ebile se bonolo, se bonolo ho se fetola le ho se laola. Sepakapaka se sireletsang hangata ke vacuum, argon, helium, naetrojene, carbon dioxide le likhase tse ling tsa inert le hydrogen, ho bola ha ammonia, carbon monoxide, phetoho ea khase ea tlhaho le likhase tse ling tse fokotsang.
E le ho ntlafatsa ts'ebetso ea lihlahisoa tsa sintered le boholo le ho nepahala ha sebopeho, hangata hoa hlokahala ho etsa sebopeho, ho qeta, ho hatella, ho qoelisoa ka oli, ho sebetsa ka mechine, phekolo ea mocheso le mekhoa e meng e latelang.
Ho phalla ha mokhoa oa ho etsa ente
