Kodi tungsten carbide ndi chiyani?

Tungsten carbideis amatchedwanso simenti carbide. Tungsten carbide ndi mtundu wa aloyi zinthu ndi refractory tungsten (W) chuma micron ufa monga pophika chachikulu, nthawi zambiri kuyambira mu gawo pakati pa 70% -97% ya kulemera okwana, ndi Cobalt (Co), Nickel (Ni), kapena Molybdenum. (Mo) ngati chomangira.

Pakali pano, W mu mawonekedwe aWCamagwiritsidwa ntchito kwambiri popanga simenti ya carbide.tungstencarbide ndi chinthu chomwe chimapangidwa pomanga tinthu tating'ono tating'ono ta WC tolimba kwambiri (Co) binder matrix ndi sintering yamadzimadzi. Pa kutentha kwambiris, WC imasungunuka kwambiri mu cobalt, ndipo binder yamadzimadzi ya cobalt imathanso kupanga WC kukhala yonyowa bwino, yomwe imatsogolera kuphatikizika bwino komanso kapangidwe kake kopanda pore popanga madzi-gawo sintering. Chifukwa chake, tungsten carbide ili ndi zinthu zambiri zabwino, monga:

*kuuma kwakukulu:Mohs’kuuma kumagwiritsidwa ntchito makamaka mumagulu amchere. The Morse scale amachokera1ku 10(Nambala yokulirapo, imakhala yolimba kwambiri).Kuuma kwa Mohs kwa tungsten carbide ndiko9 mpaka 9.5,Imadzitamandira mulingo wa kuuma kwachiwiri kwa diamondikuuma komwe kuli 10.

*Kukana kuvala: Kuuma kwapamwamba, kumapangitsanso kukana kwa tungsten carbide

*kukana kutentha: Popeza imakhala ndi mphamvu zambiri pa kutentha kwakukulu komanso kutsika kwa kutentha kowonjezera kutentha, ndizomwe zimakhala zopangira zida zodulira kuti zigwiritsidwe ntchito kumalo otentha kwambiri komanso othamanga kwambiri.

*Corrosion resistance: Tungsten carbide ndi chinthu chokhazikika, chomwe sichisungunuka m'madzi, hydrochloric acid kapena sulfuric acid. Kuphatikiza apo, sizingatheke kupanga yankho lolimba ndi zinthu zosiyanasiyana, ndipo limatha kukhalabe ndi mikhalidwe yokhazikika ngakhale m'malo ovuta.

Makamaka kuuma kwake kwakukulu ndi kukana kutentha, komwe kumakhala kosasinthika ngakhale pa 1000 ℃. Ndi zabwino zambiri, tungsten carbide itha kugwiritsidwa ntchito popanga zida zodulira, mipeni, zida zobowola, ndi zida zosagwirizana, komanso imagwiritsidwanso ntchito kwambiri m'makampani ankhondo, zakuthambo, kukonza makina, zitsulo, kubowola mafuta, zida zamigodi, zamagetsi. kulumikizana, zomangamanga, ndi zina. Ndicho chifukwa chake amatchedwa "mano mafakitale".

Tungsten carbide ndi yolimba nthawi 2-3 ngati chitsulo ndipo imakhala ndi mphamvu yopondereza kuposa zitsulo zonse zodziwika bwino zosungunuka, zoponyedwa, ndi zopukutira. Imalimbana kwambiri ndi mapindikidwe ndipo imasunga kukhazikika kwake pakuzizira kwambiri komanso kutentha kwambiri. Kukana kwake, kulimba kwake, komanso kukana kuphulika / kuphulika / kuphulika ndizopadera, zomwe zimakhala zotalika nthawi 100 kuposa zitsulo zomwe zimakhala zovuta kwambiri. imapangitsa kutentha kwambiri kuposa chitsulo chachitsulo. Tungsten carbideimathanso kuponyedwa ndikuzimitsidwa mwachangu kupanga mawonekedwe olimba kwambiri a kristalo.

Ndi chitukuko chandimakampani akumunsi, kufunikira kwa msika wa tungsten carbide kukuchulukirachulukira. Ndipo m'tsogolomu, kupanga zida zamakono zamakono, kupita patsogolo kwa sayansi ndi zamakono zamakono, komanso kukula kwachangu kwa mphamvu za nyukiliya kudzakulitsa kufunikira kwa zinthu za carbide zokhala ndi teknoloji yapamwamba komanso yapamwamba.-kukhazikika kwabwino.
