ʻOi aku ka nui o ka molybdenum i kēlā me kēia makahiki ma mua o nā metala refractory ʻē aʻe.ʻO nā molybdenum ingots, i hana ʻia e ka hoʻoheheʻe ʻana i nā electrodes P/M, e hoʻokuʻu ʻia, ʻōwili ʻia i loko o ka pepa a me ke koʻokoʻo, a laila huki ʻia i nā ʻano huahana wili ʻē aʻe, e like me ka uea a me nā paipu.Hiki ke hoʻopaʻa ʻia kēia mau mea i nā ʻano maʻalahi.Hoʻohana ʻia ʻo Molybdenum me nā mea hana maʻamau a hiki ke hoʻohana ʻia i ke kinoea tungsten arc a me ka electron beam welded, a i ʻole brazed.Loaʻa i ka Molybdenum nā mana uila a me ka wela a me ka ikaika tensile kiʻekiʻe.ʻOi aku ka nui o ka conductivity thermal ma kahi o 50% ma mua o ke kila, hao a i ʻole nickel alloys.Loaʻa iā ia ka hoʻohana ākea e like me nā heatsinks.ʻO kona conductivity uila ka mea kiʻekiʻe loa o nā metala refractory a pau, ma kahi o ka hapakolu o ke keleawe, akā ʻoi aku ka kiʻekiʻe ma mua o ka nickel, platinum, a me ka mercury.ʻO ka coefficient o ka hoʻonui wela o ka molybdenum e pili ana i ka laina me ka mahana ma luna o kahi ākea.ʻO kēia hiʻohiʻona, i ka hui pū ʻana e hoʻonui i ka hiki ke hoʻokele wela, ʻo ia ka mea e hoʻohana ai i nā thermocouples bimetal.Ua hoʻomohala ʻia nā ʻano o ka doping molybdenum pauka me ka potassium aluminosilicate e loaʻa ai kahi microstructure non-sag e like me ka tungsten.
ʻO ka hoʻohana nui ʻana no ka molybdenum ma ke ʻano he mea hoʻohuihui no nā mea hao a me nā mea kila, nā kila kila, a me nā nickel-base a i ʻole cobalt-base super-alloys e hoʻonui ai i ka ikaika wela, ka paʻakikī a me ka pale ʻana i ka corrosion.I ka ʻoihana uila a me ka uila, hoʻohana ʻia ka molybdenum i nā cathodes, nā kākoʻo cathode no nā mea radar, nā alakaʻi i kēia manawa no nā cathodes thorium, nā pāpale hope magnetron, a me nā mandrel no ka wili ʻana i nā filament tungsten.He mea koʻikoʻi ka Molybdenum i ka ʻoihana missile, kahi i hoʻohana ʻia no nā ʻāpana kūkulu wela kiʻekiʻe, e like me nā nozzles, nā ʻaoʻao alakaʻi o nā ʻaoʻao mana, kākoʻo vanes, struts, reentry cones, heal-radiation shields, heat sinks, turbine wheels, and pumps. .Ua hoʻohana ʻia ʻo Molybdenum i nā ʻoihana nuklea, kemika, aniani, a me nā ʻoihana metala.ʻO nā mahana lawelawe, no nā huila molybdenum i nā arc hoʻolālā hana, ua kaupalena ʻia i kahi kiʻekiʻe ma kahi o 1650°C (3000°F).He kūpaʻa maikaʻi ka molybdenum maʻemaʻe i ka waika hydrochloric a hoʻohana ʻia no ka lawelawe waikawa i nā ʻoihana kaʻina hana.
Molybdenum Alloy TZM
ʻO ka molybdenum alloy o ke koʻikoʻi ʻenehana koʻikoʻi ka ikaika kiʻekiʻe, kiʻekiʻe ka wela wela TZM.Hana ʻia ka mea hana e ka P / M a i ʻole ka hana arc-cast.
He kiʻekiʻe ka mahana recrystallization kiʻekiʻe o TZM a ʻoi aku ka ikaika a me ka paʻakikī ma ka lumi a me nā mahana kiʻekiʻe ma mua o ka molybdenum i hoʻohui ʻole ʻia.Hōʻike pū ia i ka ductility kūpono.ʻO kona mau ʻano mechanical maikaʻi arc ma muli o ka hoʻopuehu ʻana o nā carbide paʻakikī i ka molybdenum matrix.Ua kūpono ʻo TZM i nā noi hana wela ma muli o kona hui pū ʻana o ka paʻakikī wela kiʻekiʻe, ka conductivity thermal kiʻekiʻe, a me ka hoʻonui haʻahaʻa wela i nā kila hana wela.
Hoʻohana nui ʻia
ʻO nā mea hoʻokomo make no ka hoʻolei ʻana i ka aluminika, ka magnesium, ka zinc, a me ka hao.
Nā nozzles pōhaku.
ʻO nā kino make a me nā kuʻi no ka paʻi wela.
Nā mea hana no ka hana metala (ma muli o ke kiʻekiʻe o ka abrasion a me ke kūpaʻa kūkākūkā o TZM).
Nā pale wela no nā kapuahi, nā ʻāpana hana, a me nā mea hoʻomehana.
I ka ho'āʻo e hoʻomaikaʻi i ka ikaika wela kiʻekiʻe o P / M TZM alloys, ua hoʻomohala ʻia nā ʻāpana i hoʻololi ʻia ka titanium a me ka zirconium carbide e ka hafnium carbide.ʻOi aku ka ductile o ka molybdenum a me ka rhenium ma mua o ka molybdenum maʻemaʻe.Hiki ke ʻōwili ʻia kahi huila me 35% Re ma ka lumi wela a ʻoi aku ma mua o 95% ka emi ʻana o ka mānoanoa ma mua o ka haki ʻana.No nā kumu waiwai, ʻaʻole hoʻohana nui ʻia nā molybdenum-rhenium alloys ma ke kālepa.Hoʻohana ʻia nā huila o ka molybdenum me 5 a me 41% Re no nā uea thermocouple.
