Molybdenum imadyedwa chaka chilichonse kuposa chitsulo china chilichonse.Ingots za molybdenum, zopangidwa ndi kusungunuka kwa maelekitirodi a P/M, zimatulutsidwa, zimakulungidwa mu pepala ndi ndodo, kenako zimakokedwa ndi mawonekedwe ena a mphero, monga waya ndi machubu.Zinthuzi zimatha kusindikizidwa m'mawonekedwe osavuta.Molybdenum imapangidwanso ndi zida wamba ndipo imatha kukhala mpweya wa tungsten arc ndi electron mtengo welded, kapena brazed.Molybdenum ili ndi mphamvu zotsogola zamagetsi ndi kutentha komanso kulimba kwamphamvu kwambiri.Thermal conductivity ndi pafupifupi 50% apamwamba kuposa zitsulo, chitsulo kapena faifi tambala aloyi.Imapeza kugwiritsidwa ntchito kwakukulu ngati ma heatsinks.Mphamvu yake yamagetsi ndiyopamwamba kwambiri kuposa zitsulo zonse zokanizidwa, pafupifupi gawo limodzi mwa magawo atatu a mkuwa, koma apamwamba kuposa faifi tambala, platinamu, kapena mercury.The coefficient of matenthedwe kukula kwa molybdenum ziwembu pafupifupi linearly ndi kutentha pa osiyanasiyana.Chikhalidwe ichi, chophatikiza chidzakweza mphamvu zoyendetsa kutentha, zomwe zimagwiritsidwa ntchito mu bimetal thermocouples.Njira zopangira doping molybdenum ufa wokhala ndi potaziyamu aluminosilicate kuti mupeze mawonekedwe osasunthika ofanana ndi a tungsten apangidwanso.
Kugwiritsiridwa ntchito kwakukulu kwa molybdenum ndi monga alloying alloy for alloy and tool steels, zitsulo zosapanga dzimbiri, ndi nickel-base kapena cobalt-base super-alloys kuonjezera mphamvu zotentha, kulimba ndi kukana dzimbiri.M'mafakitale amagetsi ndi zamagetsi, molybdenum imagwiritsidwa ntchito mu cathodes, ma cathode othandizira zida za radar, mayendedwe apano a thorium cathodes, zipewa zomaliza za magnetron, ndi mandrels opangira ma tungsten filaments.Molybdenum ndiyofunikira m'makampani opangira zida zoponya, komwe imagwiritsidwa ntchito pazigawo zotentha kwambiri, monga ma nozzles, mbali zotsogola za malo owongolera, ma vanes othandizira, ma struts, ma cones obwereranso, zishango zochiritsa ma radiation, masinki otentha, mawilo a turbine, ndi mapampu. .Molybdenum yakhalanso yothandiza m'mafakitale a nyukiliya, mankhwala, magalasi, ndi zitsulo.Kutentha kwa ntchito, kwa ma aloyi a molybdenum pamapangidwe ogwiritsira ntchito arc, kumakhala kochepa mpaka 1650 ° C (3000 ° F).Molybdenum yoyera imalimbana bwino ndi hydrochloric acid ndipo imagwiritsidwa ntchito ngati acid m'mafakitale opangira mankhwala.
Molybdenum Aloy TZM
Aloyi ya molybdenum yofunikira kwambiri paukadaulo ndi aloyi yamphamvu kwambiri, yotentha kwambiri TZM.Zinthuzo zimapangidwa ndi P/M kapena njira za arc-cast.
TZM ili ndi kutentha kwapamwamba kwambiri komanso kulimba kwamphamvu komanso kuuma kwa chipinda komanso kutentha kwambiri kuposa molybdenum yopanda madzi.Ikuwonetsanso ductility yokwanira.Ubwino wake wamakina amatha chifukwa cha kubalalitsidwa kwa ma carbides ovuta mu matrix a molybdenum.TZM ndiyoyenera kugwiritsa ntchito ntchito zotentha chifukwa chophatikiza kuuma kotentha kwambiri, kukhathamira kwakukulu kwamafuta, komanso kukulitsa kwamafuta pang'ono kuzitsulo zotentha zogwirira ntchito.
Ntchito Zazikulu Zimaphatikizanso
Zida zopangira zida zopangira aluminium, magnesium, zinki, ndi chitsulo.
Ziphuphu za roketi.
Imfa matupi ndi nkhonya chifukwa otentha sitampu.
Zida zopangira zitsulo (chifukwa champhamvu kwambiri komanso kukana kwa macheza a TZM).
Zishango za kutentha kwa ng'anjo, zida zamapangidwe, ndi zinthu zotenthetsera.
Pofuna kupititsa patsogolo kutentha kwamphamvu kwa P/M TZM alloys, alloys apangidwa momwe titaniyamu ndi zirconium carbide zimasinthidwa ndi hafnium carbide.Ma aloyi a molybdenum ndi rhenium ali ndi ductile kuposa molybdenum yoyera.Aloyi yokhala ndi 35% Re imatha kukulungidwa kutentha kwa firiji mpaka kuchepetsa kutsika kwa 95% musanayambe kusweka.Pazifukwa zachuma, ma molybdenum-rhenium alloys sagwiritsidwa ntchito kwambiri pamalonda.Ma aloyi a molybdenum okhala ndi 5 ndi 41% Re amagwiritsidwa ntchito pamawaya a thermocouple.
