Ho thatafatsa

Ho thatafala ho etsoa ho sebetsana le mefokolo ea tšepe, haholo-holo e amang ho tšoarella ka kakaretso.E etsoa ka ho futhumatsa tšepe le ho e tima ka potlako hantle ha e fihla thepa e lakatsehang.Sena se homisa likaroloana e le hore se fumane litšobotsi tse ncha.

Annealing

E tloaelehileng ka ho fetisisa ka aluminium, koporo, tšepe, silevera kapa koporo, annealing e kenyelletsa ho futhumatsa tšepe ho mocheso o phahameng, ho e tšoara moo le ho e lumella hore e pholile butle-butle.Sena se etsa hore litšepe tsena ho be bonolo ho sebetsa ka sebopeho.Koporo, silevera le koporo li ka folisoa kapele kapa butle, ho latela ts'ebeliso, empa tšepe e tlameha ho lula e pholile butle kapa e ke ke ea khangoa hantle.Hangata sena se etsoa pele ho etsoa machining e le hore lisebelisoa li se ke tsa hloleha nakong ea tlhahiso.

Ho tloaeleha

Hangata e sebelisoa ka tšepe, ho tloaeleha ho ntlafatsa machinability, ductility le matla.Tšepe e futhumala ho likhato tse 150 ho isa ho tse 200 ho feta litšepe tse sebelisoang mekhoeng ea ho anela 'me e tšoareloa moo ho fihlela phetoho e lakatsehang e etsahala.Ts'ebetso e hloka hore tšepe e pholile moeeng e le ho etsa lithollo tse hloekisitsoeng tsa ferritic.Sena se boetse se na le thuso bakeng sa ho tlosa lithollo tsa columnar le karohano ea dendritic, e ka senyang boleng ha e ntse e lahla karolo.

Ho halefisa

Mokhoa ona o sebelisoa bakeng sa li-alloys tse entsoeng ka tšepe, haholo-holo tšepe.Li-alloys tsena li thata haholo, empa hangata li brittle bakeng sa merero ea tsona.Ho futhumatsa tšepe ho mocheso ka tlase ho ntlha e mahlonoko, kaha sena se tla fokotsa brittleness ntle le ho sekisetsa ho thatafala.Haeba moreki a lakatsa ho ba le polasetiki e ntlafetseng ka thata le matla a fokolang, re futhumatsa tšepe ho mocheso o phahameng.Leha ho le joalo, ka linako tse ling thepa ha e kokobele, ’me ho ka ’na ha e-ba bonolo ho reka thepa e seng e thatafalitsoe kapa ho e thatafatsa pele ho etsoa mochine.

Ho thatafatsa nyeoe

Haeba o hloka sebaka se thata empa se le bonolo, ho thatafatsa linyeoe ke bethe ea hau e ntle ka ho fetisisa.Ena ke mokhoa o tloaelehileng oa litšepe tse nang le carbon e nyenyane, joalo ka tšepe le tšepe.Ka mokhoa ona, phekolo ea mocheso e eketsa carbon holim'a metsi.Ka tloaelo u tla odara ts'ebeletso ena ka mor'a hore likotoana li entsoe ka mochini e le hore u ka li etsa hore li tšoarelle nako e telele.E etsoa ka ho sebelisa mocheso o phahameng ka lik'hemik'hale tse ling, kaha seo se fokotsa kotsi ea ho etsa hore karolo e brittle.
