Ndodo za Tungsten Copper Alloy
Kufotokozera
Copper tungsten (CuW, WCu) yakhala ikudziwika ngati chinthu chophatikizira kwambiri komanso chosakanikirana chomwe chimagwiritsidwa ntchito kwambiri ngati ma elekitirodi amkuwa a tungsten mu EDM machining ndi kukana kuwotcherera ntchito, kulumikizana kwamagetsi pama voliyumu apamwamba kwambiri, masinki otentha ndi zida zina zamagetsi zamagetsi. mu matenthedwe ntchito.
Mitundu yambiri ya tungsten / mkuwa ndi WCu 70/30, WCu 75/25, ndi WCu 80/20.Nyimbo zina zodziwika bwino zimaphatikizapo tungsten / mkuwa 50/50, 60/40, ndi 90/10.Mitundu ya nyimbo zomwe zilipo zikuchokera ku Cu 50 wt.% mpaka Cu 90 wt.%.Mitundu yathu yamkuwa ya tungsten imaphatikizapo ndodo yamkuwa ya tungsten, zojambulazo, pepala, mbale, chubu, ndodo yamkuwa ya tungsten, ndi magawo opangidwa ndi makina.

Mawonekedwe
Pakupanga aloyi yamkuwa ya tungsten, tungsten yoyera kwambiri imakanikizidwa, kulowetsedwa ndikulowetsedwa ndi mkuwa wopanda okosijeni pambuyo pa masitepe ophatikiza.The consolidated tungsten mkuwa alloy amapereka homogeneous microstructure ndi otsika mlingo wa porosity.Kuphatikizika kwa ma conductivity a mkuwa ndi kulimba kwa tungsten, kulimba, ndi malo osungunuka kwambiri kumapanga gulu lokhala ndi zinthu zambiri zodziwika bwino za zinthu zonse ziwirizi.Tungsten yolowetsedwa ndi mkuwa imakhala ndi zinthu monga kukana kwambiri kutentha kwapamwamba ndi kukokoloka kwa arc, matenthedwe abwino kwambiri amagetsi ndi magetsi komanso CTE yotsika (coefficient of thermal).
Zomwe zimapangidwira komanso zimapangidwira komanso kusungunuka kwa zinthu zamkuwa za tungsten zidzakhudzidwa ndi kusiyanasiyana kwa kuchuluka kwa mkuwa wa tungsten mu kompositi.Mwachitsanzo, monga momwe mkuwa umachulukira pang'onopang'ono, mphamvu yamagetsi ndi matenthedwe ndi kuwonjezereka kwa kutentha kumasonyeza chizolowezi chokhala champhamvu.Komabe, kachulukidwe, kukana kwamagetsi, kuuma ndi mphamvu zidzafowoka zikalowetsedwa ndi mkuwa wochepa.Chifukwa chake, kapangidwe kake koyenera ndikofunikira kwambiri mukaganizira zamkuwa wa tungsten pakufunika kogwiritsa ntchito.
Kukula kwamafuta ochepa
High matenthedwe ndi magetsi madutsidwe
High arc resistance
Kugwiritsa ntchito kochepa
Mapulogalamu
Kugwiritsa ntchito mkuwa wa Tungsten (W-Cu) kwachulukirachulukira m'magawo ambiri ndikugwiritsa ntchito chifukwa cha mawonekedwe ake apadera amakina ndi thermophysical.Zida zamkuwa za Tungsten zimawonetsa magwiridwe antchito apamwamba pazovuta, mphamvu, madulidwe, kutentha kwambiri, komanso kukana kukokoloka kwa arc.Zakhala zikugwiritsidwa ntchito kwambiri popanga magetsi, zoyatsira kutentha ndi zofalitsa, ma elekitirodi a EDM omwe amafa ndi jekeseni wa mafuta.
