Mehopolo ho Khetho ea Tungsten Carbide
Ha u khetha tungsten carbide bakeng sa ts'ebeliso e itseng, ho na le lintlha tse 'maloa tsa bohlokoa tseo u lokelang ho li ela hloko:
1. Kereiti: Tungsten carbide e tla ka limaraka tse fapaneng, e 'ngoe le e 'ngoe e na le sebopeho le litšobotsi tsa eona tse ikhethang. Kereiti e khethiloeng e lokela ho ikamahanya le litlhoko tse ikhethileng tsa ts'ebeliso mabapi le ho thatafala, ho tiea, ho hanyetsa le lintlha tse ling tse amehang.
2. Ho thatafala: Tungsten carbide e tsebahala ka ho thatafala ho ikhethang. Boemo ba boima bo lakatsehang bo tla ipapisa le thepa e sehiloeng kapa e entsoeng ka mochini. Limaraka tse thata li loketse ho seha lisebelisoa tse thata, athe limaraka tse bonolo hanyenyane li ka khethoa bakeng sa lits'ebetso moo ho leka-lekana ha boima le boima bo hlokahalang.
3. Coating: Tungsten carbide e ka tlotsoa ka lisebelisoa tse ling, joalo ka titanium nitride (TiN) kapa titanium carbonitride (TiCN), ho ntlafatsa ts'ebetso ea eona le ho lelefatsa bophelo ba lisebelisoa. Liaparo li ka ntlafatsa mafura, tsa fokotsa khohlano le ho khathala, 'me tsa fana ka khanyetso e eketsehileng ho oxidation kapa corrosion.
4. Boholo ba lijo-thollo: Boholo ba lijo-thollo tsa thepa ea tungsten carbide bo susumetsa litšobotsi tsa eona, ho kenyelletsa le ho thatafala le ho tiea. Mefuta e metle ea lijo-thollo hangata e baka boima bo phahameng empa boima bo tlase hanyane, athe lijo-thollo tse mahoashe li fana ka boima bo eketsehileng empa boima bo fokotsehile.
5. Binder Phase: Tungsten carbide hangata e kopanngoa le tšepe e kopanyang, joalo ka cobalt kapa nickel, e kopanyang likaroloana tsa carbide hammoho. Karolo ea binder e ama ho tiea ka kakaretso le matla a tungsten carbide. Peresente ea binder e lokela ho khethoa ho ipapisitsoe le tekanyo e lakatsehang lipakeng tsa boima le boima ba ts'ebeliso e itseng.
6 Lintlha tsena li tla thusa ho tseba boemo bo nepahetseng ba tungsten carbide, ho roala, le lintlha tse ling tse hlokahalang bakeng sa ts'ebetso e nepahetseng.
Ho bohlokoa ho buisana le baetsi kapa litsebi tsa tungsten carbide ho netefatsa khetho e nepahetseng ea tungsten carbide bakeng sa ts'ebeliso e itseng. Ba ka fana ka tataiso ho latela tsebo le boiphihlelo ba bona ho netefatsa litholoana tse ntle ka ho fetisisa.
Ha re khetha mophato le mophato oa tungsten carbide, re tlameha ho qala ka ho tseba ho thatafala le ho tiea ha eona. Bongata ba cobalt bo ama ho tiea le ho tiea joang? Cobalt ke tšepe e sebetsang ka ho fetesisa e sebelisoang ho tungsten carbide, 'me peresente ea eona sebopehong sa thepa e ka fetoloa ho fihlela thepa e lakatsehang.
Molao oa monoana: Cobalt e eketsehileng e bolela hore ho tla ba thata ho robeha empa hape e tla fela kapele.
1. Ho thatafala: Ho thatafala ha tungsten carbide ho eketseha ka lintho tse phahameng tsa cobalt. Cobalt e sebetsa e le thepa ea matrix e tšoarang likaroloana tsa tungsten carbide hammoho. Karolo e phahameng ea cobalt e lumella hore ho be le tlamahano e sebetsang haholoanyane, e hlahisang sebopeho sa tungsten carbide e thata le e thata.
2. Ho tiea: Matla a tungsten carbide a fokotseha ka lintho tse phahameng tsa cobalt. Cobalt ke tšepe e batlang e le bonolo ha e bapisoa le likaroloana tsa tungsten carbide, 'me palo e feteletseng ea cobalt e ka etsa hore sebopeho se be bonolo empa se se ke sa tiea. Ductility ena e ntseng e eketseha e ka lebisa phokotsong ea ho thatafala, ho etsa hore thepa e hlaselehe habonolo kapa ho robeha tlas'a maemo a itseng.
Lits'ebetsong moo ho thatafala e leng tlhokahalo ea mantlha, joalo ka ho seha lisebelisoa tse thata, litaba tse phahameng tsa cobalt hangata li khethoa ho eketsa boima le ho se sebetse ha tungsten carbide. Leha ho le joalo, lits'ebetsong tseo ho tsona ho leng bohlokoa ho tiea le ho hanyetsa tšusumetso, joalo ka ha ho sebetsanoa le likheo tse sitisang kapa ho fapana ha mojaro ka tšohanyetso, ho ka khethoa karolo e tlase ea cobalt ho matlafatsa ho tiea ha thepa le ho hana ho phunya.
Ke habohlokoa ho hlokomela hore ho na le khoebo pakeng tsa ho thatafala le ho tiea ha u lokisa litaba tsa cobalt. Ho fumana tekanyo e nepahetseng ho itšetlehile ka litlhoko tse khethehileng tsa kopo le ts'ebetso e lakatsehang ea thepa. Baetsi le litsebi tsa tungsten carbide ba ka fana ka tataiso mabapi le ho khetha dikahare tse loketseng tsa cobalt ho fihlela tekano e lakatsehang ea boima le boima ba kopo e fanoeng.
Moetsi o motle oa tungsten carbide a ka fetola litšobotsi tsa tungsten carbide ea bona ka litsela tse ngata.
Ona ke mohlala oa tlhaiso-leseling e ntle e tsoang ho moetsi oa tungsten carbide
