Mehato e Mene e Meholo ea Phekolo ea Mocheso oa Tungsten Carbide

Tungsten carbide e na le ts'ebetso e phahameng e nang le lisebelisoa tse ntle tsa mochini le 'mele, ho kenyelletsa ho hanyetsa ho hoholo, ho hanyetsa kutu, matla a ho kobeha, matla a torsion, joalo-joalo, e sebelisoa haholo bakeng sa lisebelisoa tsa ho itšeha, hlobo e batang, likarolo tsa ho roala, joalo-joalo. mekhahlelo e ka sehloohong ea phekolo ea mocheso oa tungsten carbide, e ka ntlafatsang thepa ea 'mele le ea mechine ea motsoako o thata.

Mokhoa oa ho phekola mocheso oa tungsten carbide o ka aroloa ka mehato e mene e meholo.

1. Ho tlosoa ha thepa ea ho bopa le pele ho sintering

Mothating oa pele oa sintering, ntho ea ho bopa e senyeha butle-butle kapa ea fetoha mouoane, ho sa kenyeletsoe 'mele o sintered, ka nako e ts'oanang, li-agent li etsa carburize the sintering,' me palo ea khabone e tla fapana ho latela mofuta, palo le ts'ebetso ea sintering. . Powder surface oxide e fokotsehile, 'me hydrogen e ka fokotsa cobalt le tungsten oxides mochesong o chesang. Ka karabelo e fokolang pakeng tsa carbon le oksijene, khatello ea ho kopana pakeng tsa likaroloana tsa phofo e tlosoa butle-butle. The bonding tšepe phofo qala ho arabela le recrystallization le holim'a diffusion qala ho etsahala. Matla a thibela a eketsehile.

2. Mothati oa sintering e tiileng (800 ° C - mocheso oa eutectic)

Ka pel'a karolo ea mokelikeli, ntle le ts'ebetso ea ho tsoela pele mohato o fetileng, karabelo ea mekhahlelo e tiileng le ho hasana li mpefatsoa ke keketseho ea phallo ea polasetiki, 'me ho fokotseha ho hlakileng ho hlaha' meleng oa sintered.

3. Mothati oa sintering ea mokelikeli (mocheso oa eutectic - sintering mocheso)

Ha karolo ea mokelikeli ea 'mele oa sintered e etsahala, khatello e phethoa ka potlako, ebe phetoho ea crystallization e etsahala. Mokhatlo oa motheo le sebopeho sa carbide li thehoa.

4. Sethala sa ho pholisa (mocheso oa sintering - mocheso oa kamore)

Nakong ena, likarolo tsa mokhatlo le tsa mekhahlelo ea tungsten carbide li na le liphetoho tse itseng tlas'a maemo a fapaneng a pholileng, e leng se etsang hore ho khonehe ho sebelisa tšobotsi ena; phekolo ea mocheso ea motsoako o thata o tla ntlafatsa litšobotsi tsa eona tsa 'mele le tsa mechine.

ZZBETTER e ikitlaelletsa ho hlahisa lihlahisoa tsa tungsten carbide tsa maemo a holimo le tsa boleng bo holimo. Lihlahisoa tsa rona li rekisitsoe linaheng tse ngata le libakeng tse ngata hape li etsa katleho e kholo 'marakeng oa lehae.

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.
