Cobalt ts'ebetsong ea Cemented Carbide
Cobalt ts'ebetsong ea Cemented Carbide
Matsatsing ana, kaha carbide e entsoeng ka samente e na le boima bo phahameng, ho hanyetsa ho roala, le modulus ea elastic, lisebelisoa tsa carbide tse entsoeng ka samente li bapala karolo ea bohlokoa ha u batla lisebelisoa tsa morao-rao tsa lisebelisoa, lisebelisoa tse sa senyeheng, lisebelisoa tse phahameng tsa mocheso le lisebelisoa tse thibelang kutu. Kaha Co e na le mongobo o motle le sekhomaretsi ho WC le TiC, e sebelisoa haholo e le moemeli oa ho khomarela indastering e le lisebelisoa tsa ho itšeha. Ho sebelisa Co e le moemeli oa ho khomarela ho etsa hore carbide e entsoeng ka samente e be le melemo ea matla a phahameng, boima bo phahameng, le khanyetso e phahameng ea ho apara.
Leha ho le joalo, ka lebaka la theko e phahameng ea tšepe ea cobalt le khaello ea lisebelisoa, batho ba 'nile ba batla libaka tsa tšepe ea cobalt. Lisebelisoa tse tloaelehileng tse seng li sebelisitsoe hona joale ke nickel le iron. Ka bomalimabe, ho sebelisa phofo ea tšepe e le moemeli oa ho khomarela hangata ho na le matla a tlaase a mochine. Ho sebelisa nickel e hloekileng e le moemeli oa ho khomarela carbide 'meleng le mechine ea carbide e entsoeng ka samente ha e ntle joaloka ba sebelisang cobalt joaloka moemeli oa ho khomarela. Taolo ea ts'ebetso e boetse e thata haeba u sebelisa nickel e hloekileng e le moemeli oa ho khomarela.
Karolo ea cobalt ka carbide e entsoeng ka samente e tšoana le tšepe ea adhesion. Cobalt e ka ama ho tiea ha carbide e entsoeng ka samente ka bokhoni ba eona ba polasetiki ea deformation mocheso oa kamore. Carbide e entsoeng ka samente e thehoa ka mokhoa oa sintering. Cobalt le nickel li fetoha sekhomaretsi sa bokahohle sa carbide e entsoeng ka samente. Cobalt e na le tšusumetso ea bohlokoa tlhahisong ea carbide e samente, 'me hoo e ka bang 90% ea li-carbide tse entsoeng ka samente li sebelisa cobalt joalo ka sekhomaretsi.
Carbide e entsoeng ka samente e entsoe ka li-carbide tse thata le litšepe tse bonolo tsa adhesion. Carbide e fana ka bokhoni ba ho mamella mojaro le ho roala ho hanyetsa alloy, 'me moemeli oa ho khomarela o fana ka bokhoni ba ho holofala ka polasetiki mocheso oa kamore. Tšusumetso e matla ea carbide. Ho etsa bonnete ba hore lihlahisoa tsa sintered li maemong a matle, li-adhesion agents li phetha karolo ea bohlokoa ho kolobisa carbide e entsoeng ka samente.
Letoto la li-tungsten-cobalt carbides li sebelisetsoa ho seha malebela a lisebelisoa le lisebelisoa tsa merafo tse hlokang ho sebetsa libakeng tse thata haholo. Lisebelisoa tse ling tsa ho buoa tse tšoarellang le limatlase tse sa feleng le tsona li entsoe ka li-alloys tsa cobalt.
Ductility le ho tiea ha lihlahisoa tsa carbide tse entsoeng ka samente li ka fanoa ke moemeli oa ho khomarela. Ka nako e ts'oanang, moemeli oa ho khomarela o fana ka bokhoni ba carbide e entsoeng ka samente e phahameng e qhibilihisang e ka etsoa likarolo ka mocheso o ka tlaase ho sebaka sa ho qhibiliha.
Moemeli ea molemo ka ho fetisisa oa ho khomarela o lokela ho khona ho kolobisa ka ho feletseng sebaka se phahameng sa ho qhibiliha sa carbide e entsoeng ka samente. Tšepe, cobalt, le nickel kaofela li ka fihlela litlhoko tsa sesebelisoa se setle sa ho khomarela.
Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
