Terminology Mabapi le Tungsten Carbide

Ka nts'etsopele ea theknoloji, batho ba lelekisa lisebelisoa tse betere, le lisebelisoa bakeng sa kaho ea bona le khoebo. Tlas'a sepakapaka sena, tungsten carbide e nka karolo ea bohlokoa indastering ea sejoale-joale. 'Me sehloohong sena, ho tla hlahisoa mantsoe a mang mabapi le tungsten carbide.

1. Carbide e entsoeng ka samente

Carbide e entsoeng ka samente e bolela motsoako oa sintered o entsoeng ka li-carbide tsa tšepe tse refractory le li-binders tsa tšepe. Har'a li-carbide tsa tšepe, tungsten carbide, titanium carbide, tantalum carbide, joalo-joalo ke li-carbide tse sebelisoang hona joale. 'Me setlamo sa tšepe se sebelisoang ka ho fetisisa ke phofo ea cobalt, le li-binder tse ling tsa tšepe tse kang nickel, le tšepe, le tsona li tla sebelisoa ka linako tse ling.

2. Tungsten carbide

Tungsten carbide ke mofuta oa carbide e entsoeng ka samente, e entsoeng ka phofo ea tungsten carbide le li-binders tsa tšepe. Ka ntlha e phahameng ea ho qhibiliha, lihlahisoa tsa tungsten carbide li ke ke tsa etsoa e le lisebelisoa tse ling. Metallurgy ea phofo ke mokhoa o tloaelehileng oa ho etsa lihlahisoa tsa tungsten carbide. Ka liathomo tsa tungsten le liathomo tsa carbon, lihlahisoa tsa tungsten carbide li na le thepa e ngata e ntle, e etsang hore e be lisebelisoa tse tsebahalang indastering ea sejoale-joale.

3. Ho teteana

Density e bolela karo-karolelano ea boima ho bophahamo ba thepa. Bophahamo ba eona bo boetse bo na le molumo oa li-pores ka thepa.

Ka lihlahisoa tsa tungsten carbide, cobalt kapa likaroloana tse ling tsa tšepe li teng. Sehlopha se tloaelehileng sa tungsten carbide YG8, se nang le 8% cobalt, se na le boima ba 14.8g/cm3. Ka hona, ha litaba tsa cobalt ka motsoako oa tungsten-cobalt li ntse li eketseha, boima ba kakaretso bo tla fokotseha.

4. Ho thatafala

Ho thatafala ho bolela bokhoni ba thepa ho hanyetsa deformation ea polasetiki. Vickers hardness le Rockwell hardness hangata li sebelisetsoa ho lekanya ho thatafala ha lihlahisoa tsa tungsten carbide.

Vickers hardness e sebelisoa haholo linaheng tse ling. Mokhoa ona oa ho lekanya boima o bolela boleng ba boima bo fumanoeng ka ho lekanya boholo ba ho indentation ka ho sebelisa taemane ho phunyeletsa bokaholimo ba sampuli tlas'a boemo bo itseng ba mojaro.

Rockwell hardness ke mokhoa o mong oa ho lekanya boima bo sebelisoang hangata. E lekanya bothata ka ho sebelisa botebo ba ho kenella ha khoune e tloaelehileng ea taemane.

Ka bobeli mokhoa oa ho lekanya boima ba Vickers le mokhoa oa ho lekanya boima ba Rockwell o ka sebelisoa bakeng sa ho lekanya ho thatafala ha carbide e entsoeng ka samente, 'me tse peli li ka fetoloa ka bobeli.

Ho thatafala ha tungsten carbide ho tloha ho 85 HRA ho isa ho 90 HRA. Sehlopha se tloaelehileng sa tungsten carbide, YG8, se na le boima ba 89.5 HRA. Sehlahisoa sa tungsten carbide se nang le boima bo phahameng se ka mamella tšusumetso le ho apara hantle, kahoo se ka sebetsa nako e telele. Joalo ka bonder, cobalt e fokolang e baka bothata bo betere. Mme khabone e tlase e ka etsa hore tungsten carbide e be thata. Empa decarbonization e ka etsa hore tungsten carbide e senyehe habonolo. Ka kakaretso, tungsten carbide e ntle e tla eketsa boima ba eona.

5. Matla a ho kobeha

Mohlala o atolosoa e le leballo le tšehelitsoeng feela holim'a li-fulcrum tse peli, 'me mojaro o sebelisoa moleng o bohareng oa li-fulcrum tse peli ho fihlela sampole e robeha. Boleng bo baloang ka mokhoa o ts'oanelang ho sebelisoa ho ea ka mojaro o hlokahalang bakeng sa ho robeha le sebaka sa sefapano sa sampuli. E boetse e tsejoa e le matla a ho phunyeha a phunyeletsang kapa ho hanyetsa ho kobeha.

Ka WC-Co tungsten carbide, matla a flexural a eketseha ka keketseho ea cobalt content ea tungsten-cobalt alloy, empa ha litaba tsa cobalt li fihla hoo e ka bang 15%, matla a flexural a fihla ho boleng bo phahameng, ebe o qala ho theoha.

Matla a ho kobeha a lekantsoe ka karolelano ea litekanyetso tse lekantsoeng tse 'maloa. Boleng bona bo tla fetoha hape ha geometry ea mohlala, boemo ba bokaholimo, khatello ea maikutlo ea kahare, le bofokoli ba kahare ba thepa e fetohang. Ka hona, matla a flexural ke tekanyo ea matla feela, 'me boleng ba matla a flexural bo ke ke ba sebelisoae le motheo oa khetho ea lintho tse bonahalang.

6. Transverse rupture matla

Transverse rupture matla ke bokhoni ba tungsten carbide ho hanela ho kobeha. Tungsten carbide e nang le matla a ntlafetseng a ho phunyeha ho thata ho feta ho senya tlas'a tšusumetso. Tungsten carbide e ntle e na le matla a betere a ho phunyeha. 'Me ha likaroloana tsa tungsten carbide li ajoa ka tsela e tšoanang, transverse e molemo,' me tungsten carbide ha e bonolo ho e senya. Matla a phatlohileng a lihlahisoa tsa YG8 tungsten carbide a ka bang 2200 MPa.

7. Matla a qobellang

Coercive force ke matla a masala a makenete a lekantsoeng ka ho holisa thepa ea makenete ka har'a carbide e samenteng ho ea sebakeng se tletseng 'me e ntan'o e senya.

Ho na le kamano e tobileng pakeng tsa karolelano ea boholo ba karoloana ea karolo ea samente ea carbide le matla a qobellang. Ha boholo ba karoloana ea karoloana ea sekhahla sa makenete bo ntlafala, ho tla ba le boleng bo phahameng ba matla a coercive. Ka laboratoring, matla a qobelloang a lekoa ke motho ea lekang matla a qobelloang.

Tsena ke mantsoe a tungsten carbide le thepa ea eona. Mareo a mang a mang a tla boela a hlahisoe lihloohong tse latelang.

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.
