Kodi mumadziwa bwanji za Tungsten Carbide Powder?

Tungsten carbide imadziwika kuti ndi imodzi mwazinthu zovuta kwambiri padziko lapansi, ndipo anthu amazidziwa bwino zamtunduwu. Koma bwanji za tungsten carbide ufa, zopangira tungsten carbide mankhwala? M'nkhaniyi, tidziwa chinachake chokhudza tungsten carbide powder.

Monga zopangira

Zogulitsa za Tungsten carbide zonse zimapangidwa ndi tungsten carbide powder. Popanga, ma ufa ena adzawonjezedwa ku tungsten carbide ufa ngati chomangira kuphatikiza tinthu tating'ono ta tungsten carbide mwamphamvu kwambiri. M'malo abwino, kuchuluka kwa tungsten carbide ufa kumapangitsa kuti zinthu za tungsten carbide zitheke. Koma kwenikweni, tungsten carbide yoyera ndiyosalimba. Ichi ndichifukwa chake binder ilipo. Dzina la giredi nthawi zonse limatha kukuwonetsani kuchuluka kwa zomangira. Monga YG8, yomwe ndi giredi wamba yomwe imagwiritsidwa ntchito popanga zinthu za tungsten carbide, ili ndi 8% ya ufa wa cobalt. Kuchuluka kwa titaniyamu, cobalt, kapena faifi tambala kumatha kusintha magwiridwe antchito a tungsten carbide. Tengani cobalt mwachitsanzo, gawo labwino kwambiri komanso lodziwika bwino la cobalt ndi 3% -25%. Ngati cobalt ndi yoposa 25%, tungsten carbide idzakhala yofewa chifukwa cha zomangira zambiri. Tungsten carbide iyi singagwiritsidwe ntchito kupanga zida zina. Ngati zosakwana 3%, tinthu tating'onoting'ono ta tungsten carbide ndizovuta kumangirira ndipo zinthu zopangidwa ndi tungsten carbide pambuyo pa sintering zimakhala zolimba kwambiri. Ena a inu mungakhale osokonezeka, chifukwa chiyani opanga amati tungsten carbide ufa ndi zomangira amapangidwa ndi 100% zopangira zoyera? 100% zopangira zoyera zikutanthauza kuti zida zathu sizidzabwezeredwa kuchokera kwa ena.

Asayansi ambiri akuyesera kupeza njira yabwino yopangira kuti achepetse kuchuluka kwa cobalt, ndikusungabe machitidwe abwino a tungsten carbide.

Zochita za tungsten carbide powder

Tungsten carbide ili ndi makhalidwe ambiri, kotero sizovuta kuganiza kuti tungsten carbide ufa ulinso ndi ubwino ndi makhalidwe ambiri. Tungsten carbide ufa siwosungunuka, koma umasungunuka mu aqua regia. Chifukwa chake zinthu za tungsten carbide nthawi zonse zimakhala zokhazikika pamakina. Tungsten carbide ufa uli ndi malo osungunuka a 2800 ℃ ndi malo otentha ozungulira 6000 ℃. Chifukwa chake cobalt ndiyosavuta kusungunuka pomwe ufa wa tungsten carbide ukadali wotentha kwambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
