U tseba hakae ka likhoele tsa tungsten carbide?

Ha ho na taba hore na u sebelisitse likhoele tsa tungsten carbide kapa che, empa ke lumela hore u kanna oa tseba ho hong ka tungsten carbide. Hangata re ka bona lihlahisoa tsa tungsten carbide bophelong ba rona. Ka mohlala, ha re palama bese, re ka bona hamore pel’a fensetere ea bese, ena ke eona eo re e sebelisang ho pshatla fensetere hore re balehe ha re thulana le boemo ba tšohanyetso. Ka kakaretso, mofuta ona oa hamore o tla etsoa ka tungsten carbide, ka lebaka la boima ba eona bo phahameng. Haeba u tloaetse ho apara oache, ho boetse ho na le alloy e thata ka har'a oache ka lebaka la ho hanyetsa ha eona haholo ......

Ho thatafala ha carbide e entsoeng ka samente ke ea bobeli ka mor'a taemane e nang le khanyetso e phahameng haholo. Na ua tseba hore na ke hobane'ng ha carbide e entsoeng ka samente e thata hakaale?

Hobane tungsten carbide ke sehlahisoa sa sintered metallurgical sa mofuta oa phofo. E entsoe ka sebōpi sa vacuum kapa Hydrogen phokotso ea sebōpi se nang le phofo ea refractory Tungsten material (WC) micron e le motsoako o ka sehloohong le Cobalt (Co), Nickel (Ni), kapa Molybdenum (Mo) e le tlamahano.

Tungsten carbide ha e na feela litšoaneleho tsa ho thatafala ho hoholo le ho haneloa ho hoholo, empa e boetse e na le khanyetso ea kutu le botsitso bo hlakileng tlas'a mocheso o phahameng (esita le 500 ºC ha e le hantle ha e fetohe 'me ho 1000 ºC e ntse e le thata haholo)
Li-strip tsa Tungsten carbide li na le litšobotsi tsohle tsa tungsten carbide.





Hlahisa ts'ebetso ea likhoele tsa tungsten carbide
Li-strip tsa carbide li bua ka mahlakore a mabeli,tse tsejoang hape e le lifolete tsa tungsten carbide. E hlahisoa ka phofo (Haholo-holo WC le Co powder ho latela foromo) motsoako, ho sila ka bolo, ho omisa tora ea ho fafatsa, extruding, drying, sintering, (le ho seha kapa ho sila ha ho hlokahala) tlhahlobo ea ho qetela, ho paka ka nako eo.ho fana, tlhahlobo e bohareng e etsoa ka mor'a ts'ebetso e 'ngoe le e' ngoe ho etsa bonnete ba hore lihlahisoa tse tšoanelehang feela li ka isoa ts'ebetsong e latelang ea tlhahiso.

Taolo ea boleng ba likhoele tsa tungsten carbide
HRA tester, TRS tester, Metallographic microscope(Sheba microstructure), coercive force tester, cobalt magnetic tester e sebelisoa ho hlahloba le ho etsa bonnete ba hore thepa ea carbide strip e tšoaneleha hantle, ntle le moo, tlhahlobo ea ho theoha e eketsoa ka ho khetheha tlhahlobong ea carbide strip ho. etsa bonnete ba hore ha ho na bofokoli ba lintho tse bonahalang lebaleng lohle le lelelele. Le tlhahlobo ea boholo ho latela taelo.

Tšebeliso ea likhoele tsa tungsten carbide
Litaba tsa WC le Co in tungsten carbide strips tse nang le ts'ebeliso e fapaneng ha li lumellane, 'me mefuta ea ts'ebeliso e pharaletseng. Tungsten carbide strip e tsejoa haholo e le mofuta o le mong oa sesebelisoa sa ho seha carbide. Ke efe e loketseng ho alafa patsi e tiileng, lepolanka la ho kuta, le letlapa la fiber e bohareng? Lithapa tsa carbide tse entsoeng ka samente li ka sebelisoa ho etsa lisebelisoa tsa ho betla lehong, joalo ka lisebelisoa tsa ho etsa, reamer, mahare a thipa a serrated, le mahare a fapaneng.

Khetha kereiti
Ho thatafala hoa eketseha ha cobalt e fokotseha le
bophara ba likaroloana tsa tungsten carbide lia fokotseha. Matla a flexural a eketseha joalo ka
cobalt ea eketseha 'me bophara ba tungsten carbide bo fokotseha.
Ka hona, ke mohato oa bohlokoa haholo ho khetha kereiti e loketseng ho latela
mefuta e fapaneng ea lisebelisoa, lisebelisoa tse fapaneng tse sebetsoang, le libaka tse fapaneng tsa ts'ebetso.
Khetho e sa nepahalang ea limaraka e tla baka mathata a kang ho pshatla, ho robeha, ho apara habonolo,
le bophelo bo bokgutshwane.

Ho na le limaraka tse ngata tseo u ka li khethang

Joang ho khetha mophato o nepahetseng kapele?
Haeba o sa tsebe hore na sehlahisoa sa hau se loketse sehlopha sefe, Rea u amohelaIteanye le rona.
