Lihlahisoa tsa tšepe tsa tungsten li na le hoo e ka bang 18% tungsten, tšepe ea tungsten ke ea carbide e entsoeng ka samente, eo hape e bitsoang tungsten-titanium alloy.Ho thatafala ke 10K sekaleng sa Vickers, ea bobeli feela ho daemane.Ka lebaka la sena, lihlahisoa tsa tšepe tsa tungsten, e na le tšobotsi ea hore ha ho bonolo ho e apara.Lihlahisoa tsa tungsten carbide hangata li sebelisoa ho lithulusi tsa lathe, likotoana tsa ho cheka, likotoana tse sehang likhalase, li-cutters tsa lithaele, tse thata, ha li tšabe ho ts'oaroa, empa li brittle.Ke tšepe e sa tloaelehang.
Tungsten carbide sintering sebopeho:
Tungsten carbide sintering molding ke ho hatella phofo ka har'a lintho tse bonahalang, ebe ka seboping sa sintering se futhumetse mocheso o itseng 〔sintering mocheso〕, ebe o e boloka nako e itseng (nako ea ho boloka mocheso), ebe oe pholisa, e le ho fumana thepa ea tšepe ea tungsten ka ts'ebetso e hlokahalang.
Ts'ebetso ea sintering ea tungsten carbide e ka aroloa ka mekhahlelo e mene ea mantlha:
1: ho tlosoa ha moemeli oa ho etsa, ho senya nako ea pele ka ho eketseha ha mocheso, moemeli oa ho bopa o senyeha butle-butle kapa oa fetoha mouoane, o qheleloa ka thōko ho 'mele o sintered, ka nako e ts'oanang, moemeli oa ho theha ho feta kapa ka tlaase ho' mele o sintered. keketseho ea k'habone, palo ea keketseho ea khabone e tla ba le mofuta oa ho bopa, palo ea ts'ebetso ea sintering le e fapaneng le phetoho.
Li-oxide tsa phofo li fokotsehile, ka mocheso oa sintering, haedrojene e ka fokotsoa cobalt le tungsten oxides, haeba ho tlosoa ha vacuum ea ho etsa moemeli le sintering, k'habone le oksijene itšoara joang ha e matla.Likaroloana tsa phofo li botsa khatello ea maikutlo e tlosoa butle-butle, phofo ea tšepe e kopantsoeng e ile ea qala ho hlahisa lihlahisoa tsa ho khutla le ho kenngoa hape, ho phatloha ha holim'a metsi ho ile ha qala ho etsahala, matla a briquette a ntlafetse.
2: sethala se tiileng sa sintering (800 ° C - mocheso oa eutectic)
Nakong ea mocheso pele ho hlaha karolo ea mokelikeli, ntle le ho tsoela pele ka ts'ebetso e hlahang sethaleng se fetileng, karabelo e tiileng ea mohato le ho hasana hoa matlafala, ho phalla ha polasetiki hoa ntlafatsoa, 'me' mele oa sintered o bonahala o fokotseha haholo.
3: Sethala sa sintering sa mokelikeli (mocheso oa eutectic - mocheso oa sintering>)
Ha karolo ea mokelikeli e hlaha 'meleng oa sintered, ho fokotseha ho phethoa ka potlako haholo, ho lateloa ke phetoho ea crystalline ho theha mokhatlo oa motheo le sebopeho sa motsoako.
4: Mohato oa ho Pholisa (Mocheso oa Sintering - Mocheso oa Kamore>)
Mothating ona, mokhatlo o hlophisitsoeng le karolo ea ho hlophisoa ha tšepe tungsten le maemo a fapaneng tsidifatso le hlahisa liphetoho tse itseng, o ka etsa tshebediso ya tšobotsi ena, mocheso kalafo ya tungsten tšepe ho ntlafatsa thepa lona 'meleng le mechine.
Melamu ea Tungsten ke lihlahisoa tsa tungsten tse chitja kapa tse lisekoere.Tungsten ke tšepe e thata haholo, e teteaneng e nang le mocheso o phahameng ka ho fetisisa oa ho qhibiliha ho feta tšepe leha e le efe: 6,192°F (3,422°C).Ke ntho ea lik'hemik'hale e nang le nomoro ea athomo ea 74. Ke ntho ea lik'hemik'hale e nang le nomoro ea athomo ea 74. tungsten e na le matla a ho thibela ho bola 'me ha e amehe hanyenyane ke li-acids.Melamu ea Tungsten e hlahisoa ka mekhoa ea ho etsa phofo ea metallurgy.
Mefuta ea lithupa tsa Tungsten ka kakaretso li arotsoe ka lithupa tse hloekileng tsa tungsten, lithupa tsa tungsten carbide, lithupa tsa alloy tsa tungsten, melamu ea koporo ea tungsten, lithupa tsa conductor tsa tungsten joalo-joalo.Tšebeliso ea lithupa tsa Tungsten Melamu ea Tungsten e ka sebelisoa haholo ho khantša, ho futhumatsa le ho boenjiniere ba mechine ea elektroniki.Ho feta moo, e ka sebelisoa ho etsa mohloli oa leseli la motlakase, li-bulbs tsa koloi le literekere, ho etsa lithupa tsa mahlakoreng a marang-rang, liforeimi, lithapo, li-electrode, li-heaters le lisebelisoa tsa ho kopana, li-drill tsa PCB, li-drill bits, li-mill tsa ho qetela joalo-joalo.
Phepelo ea indasteri ea Zigong Xinhua ea lithupa tsa tungsten e ka hlahisoa ka likotoana tse bolelele bo sa reroang kapa ea khaoloa ho isa bolelele bo batloang ke moreki ka bophara ho tloha lisenthimithara tse 0.020 ho isa ho 0.750.Mamello e menyenyane e ka qotsoa ka kopo.Ntle le moo, ho na le mefuta e meraro e fapaneng ea litlhare kapa kalafo ea holim'a metsi ho ipapisitsoe le tšebeliso e lakatsehang.
