Tungsten carbide ke eng?

Tungsten carbideis e tsejoang hape ka hore ke cemented carbide. Tungsten carbide ke mofuta oa alloy material e nang le "refractory tungsten" (W) material micron powder e le motsoako o ka sehloohong, ka kakaretso o tloha ka tekanyo e pakeng tsa 70% -97% ea boima bohle, le Cobalt (Co), Nickel (Ni), kapa Molybdenum. (Mo) joalo ka setlamo.

Hajoale, W ka sebopeho saWCe sebelisoa haholo tlhahisong ea carbide e entsoeng ka samente.tungstencarbide ke thepa e entsoeng ka ho kopanya likaroloana tse thata haholo tsa WC ka har'a matrix a tlamang a cobalt (Co) ka sintering ea mokelikeli. Ka mocheso o phahamengs, WC e qhibiliha haholo ka cobalt, 'me metsi a cobalt binder a ka boela a etsa hore WC e be boemong bo botle ba ho koloba, e leng se lebisang ho compactness e ntle le sebopeho se se nang pore ts'ebetsong ea mokelikeli-phase sintering. Ka hona, tungsten carbide e na le letoto la thepa e ntle haholo, joalo ka:

*bothata bo phahameng:Mohs’ho thatafala ho sebelisoa haholo-holo ho arola liminerale. Sekala sa Morse se tsoa ho1ho ea ho 10(Ha palo e kholoanyane, boima ba bona bo phahame).Boima ba Mohs ba tungsten carbide ke9 ho isa ho 9.5,E ithorisa ka boemo ba boima ba bobeli ho feta taemanee leng boima ba 10.

*wear resistance: Ha boima bo phahame, ho tla ba betere ho hanyetsa ha tungsten carbide

*ho hanyetsa mocheso: Kaha e na le matla a phahameng mochesong o phahameng le mocheso o fokolang oa ho atolosa mocheso, ke lisebelisoa tse tala tse nepahetseng bakeng sa lisebelisoa tsa ho itšeha tse lokelang ho sebelisoa sebakeng se phahameng sa mocheso le lebelo le phahameng.

*Corrosion resistance: Tungsten carbide ke ntho e tsitsitseng haholo, e ke keng ea qhibiliha ka metsing, hydrochloric acid kapa sulfuric acid. Ho phaella moo, ho ke ke ha etsahala hore ho thehoe tharollo e tiileng e nang le likarolo tse sa tšoaneng, 'me e ka boloka litšobotsi tse tsitsitseng esita le libakeng tse thata.

Haholo-holo boima ba eona bo phahameng le ho hanyetsa mocheso, tse lulang li sa fetohe esita le ho 1000 ℃. Ka melemo e mengata, tungsten carbide e ka sebelisoa ho etsa lisebelisoa tsa ho seha, lithipa, lisebelisoa tsa ho cheka le likarolo tse sa sebetseng, hape e sebelisoa haholo indastering ea sesole, sefofane, ho sebetsa ka mechine, metallurgy, ho cheka petroleum, lisebelisoa tsa morafo, lisebelisoa tsa elektroniki. likhokahano, kaho, le mafapha a mang. Ke ka lebaka leo e tsejoang e le "meno a indasteri".

Tungsten carbide e thata ka makhetlo a 2-3 joalo ka tšepe 'me e na le matla a hatellang a fetang litšepe tsohle tse tsejoang tse qhibilihisitsoeng, tse entsoeng le tse entsoeng. E hanana haholo le deformation mme e boloka botsitso ba eona maemong a batang haholo le mocheso o chesang. Tšusumetso ea eona ea ho hanyetsa, ho tiea, le ho hanyetsa galling/abrasions/rosions ke e ikhethang, e nka nako e telele ho isa ho 100 ho feta tšepe maemong a feteletseng. e tsamaisa mocheso kapele ho feta tšepe ea sesebelisoa. Tungsten carbidee ka boela ea lahleloa le ho tima ka potlako ho theha sebopeho sa kristale se thata haholo.

Ka tsoelopele eatheindasteri e tlase, tlhoko ea 'maraka ea tungsten carbide e ntse e eketseha. 'Me nakong e tlang, ho etsoa ha lisebelisoa tsa theknoloji e phahameng, tsoelo-pele ea mahlale a morao-rao le theknoloji, le nts'etsopele e potlakileng ea matla a nyutlelie e tla eketsa haholo tlhokahalo ea lihlahisoa tsa carbide tse nang le lisebelisoa tse phahameng tsa theknoloji le tse phahameng.-botsitso ba boleng.
