Zolingalira Pakusankha kwa Tungsten Carbide
Zolingalira Pakusankha kwa Tungsten Carbide
Posankha tungsten carbide pa ntchito inayake, pali zinthu zingapo zofunika kuziganizira:
1. Gulu: Tungsten carbide imabwera m'magiredi osiyanasiyana, iliyonse ili ndi mawonekedwe ake komanso mawonekedwe ake. Gulu losankhidwa liyenera kugwirizana ndi zofunikira za pulogalamuyo potengera kuuma, kulimba, kukana kuvala, ndi zina zofunika.
2. Kuuma: Tungsten carbide imadziwika ndi kuuma kwake kwapadera. Kuuma kofunikira kumatengera zinthu zomwe zimadulidwa kapena makina. Magiredi olimba ndi oyenera kudula zida zolimba, pomwe magiredi ofewa pang'ono atha kukhala okondedwa pamapulogalamu omwe kulimba ndi kulimba ndikofunikira.
3. Kupaka: Tungsten carbide ikhoza kupakidwa ndi zinthu zina, monga titanium nitride (TiN) kapena titanium carbonitride (TiCN), kuti iwongolere magwiridwe antchito ake ndikutalikitsa moyo wa zida. Zopaka zimatha kukhathamiritsa mafuta, kuchepetsa mikangano ndi kuvala, komanso kupereka kukana kwina kwa okosijeni kapena dzimbiri.
4. Kukula kwa Njere: Kukula kwa njere za tungsten carbide kumakhudzanso mawonekedwe ake, kuphatikiza kulimba ndi kulimba. Kukula kwambewu zocheperako nthawi zambiri kumabweretsa kulimba kwambiri koma kutsika pang'ono, pomwe mbewu zokhuthala zimapereka kuuma kowonjezereka koma kumachepetsa kulimba.
5. Binder Phase: Tungsten carbide nthawi zambiri imasakanizidwa ndi zitsulo zomangira, monga cobalt kapena faifi tambala, zomwe zimagwirizanitsa tinthu ta carbide. Gawo la binder limakhudza kulimba ndi mphamvu zonse za tungsten carbide. Maperesenti omangira ayenera kusankhidwa kutengera momwe akufunira pakati pa kuuma ndi kulimba kwa ntchitoyo.
6. * Zinthu izi zithandizira kudziwa giredi yoyenera ya tungsten carbide, zokutira, ndi zina zofunika kuti zigwire bwino ntchito.
Ndikofunika kukaonana ndi opanga tungsten carbide kapena akatswiri kuti muwonetsetse kusankha kolondola kwa tungsten carbide pa ntchito inayake. Atha kupereka chitsogozo potengera zomwe akudziwa komanso zomwe adakumana nazo kuti atsimikizire zotsatira zabwino.
Posankha kalasi ndi kalasi ya tungsten carbide, choyamba tiyenera kudziwa kuuma kwake ndi kulimba kwake. Kodi kuchuluka kwa cobalt kumakhudza bwanji kulimba ndi kuuma kwake? Kuchuluka kwa cobalt mu tungsten carbide kumakhudza kwambiri kulimba ndi kulimba kwake. Cobalt ndiye chitsulo chophatikizika kwambiri chomwe chimagwiritsidwa ntchito mu tungsten carbide, ndipo kuchuluka kwake pamapangidwe azinthuzo kumatha kusinthidwa kuti akwaniritse zomwe mukufuna.
Lamulo la chala chachikulu: Cobalt yochulukirapo imatanthawuza kuti idzakhala yovuta kuthyoka koma idzatha msanga.
1. Kuuma: Kulimba kwa tungsten carbide kumawonjezeka ndi kuchuluka kwa cobalt. Cobalt imagwira ntchito ngati matrix omwe amagwirizanitsa tinthu tating'ono ta tungsten carbide. Kuchulukirachulukira kwa cobalt kumapangitsa kumangirira kogwira mtima, zomwe zimapangitsa kuti pakhale mawonekedwe olimba komanso olimba a tungsten carbide.
2. Kulimba: Kulimba kwa tungsten carbide kumachepa ndi kuchuluka kwa cobalt. Cobalt ndi chitsulo chofewa kwambiri poyerekeza ndi tinthu tating'onoting'ono ta tungsten carbide, ndipo kuchuluka kwa cobalt kumatha kupanga kapangidwe kake kocheperako koma kocheperako. Kuwonjezeka kwa ductility kumeneku kungayambitse kuchepa kwa kulimba, kupangitsa kuti zinthuzo zikhale zosavuta kuphwanyidwa kapena kusweka pansi pazifukwa zina.
M'mapulogalamu omwe kuuma ndikofunikira kwambiri, monga kudula zida zolimba, zokhala ndi cobalt zapamwamba nthawi zambiri zimakonda kukulitsa kuuma komanso kuvala kukana kwa tungsten carbide. Komabe, m'mapulogalamu omwe kulimba ndi kukana kwamphamvu ndikofunikira, monga pothana ndi mabala osokonekera kapena kusinthana kwa katundu mwadzidzidzi, zinthu zotsika za cobalt zitha kusankhidwa kuti zithandizire kulimba kwa zinthuzo komanso kukana kudulidwa.
Ndikofunika kuzindikira kuti pali kusinthanitsa pakati pa kuuma ndi kulimba pamene mukusintha zomwe zili mu cobalt. Kupeza malire oyenerera kumatengera zofunikira zomwe zimagwiritsidwa ntchito komanso zomwe mukufuna kuchita. Opanga ndi akatswiri a tungsten carbide atha kupereka chitsogozo pakusankha zoyenera za cobalt kuti mukwaniritse kuuma komanso kulimba kwa ntchito yomwe mwapatsidwa.
Wopanga tungsten carbide wabwino amatha kusintha mawonekedwe a tungsten carbide yawo m'njira zingapo.
Ichi ndi chitsanzo cha chidziwitso chabwino kuchokera ku tungsten carbide kupanga
