Yakawanda molybdenum inopedzwa gore negore kupfuura chero imwe simbi inofuratira.Molybdenum ingots, inogadzirwa nekunyunguduka kweP/M maelectrode, anoburitswa, akakungurutswa kuita pepa netsvimbo, uye ozokweverwa kune mamwe maumbirwo echigayo, sewaya uye tubing.Zvinhu izvi zvinokwanisa kudhindwa kuita zvimiro zviri nyore.Molybdenum inogadzirwawo nematurusi akajairwa uye inogona kuve gasi tungsten arc uye erekitironi danda rakasungwa, kana brazed.Molybdenum ine simba rakatanhamara remagetsi uye kupisa-kuitisa uye yakanyanya kusimba simba.Thermal conductivity inenge 50% yakakwirira kudarika yesimbi, iron kana nickel alloys.Iyo nekudaro inowana kushandiswa kwakakura seheatsinks.Mafambisirwo ayo emagetsi ndiwo akakwirira pane ese simbi dzinoramba, chinenge chikamu chimwe muzvitatu chemhangura, asi chakakwirira kudarika nickel, platinum, kana mercury.Iyo coefficient yekuwedzera kwekupisa kwe molybdenum plots ingangoita linear netembiricha pamusoro pehupamhi.Hunhu uhu, mukubatana huchasimudza hunyanzvi hwekuita kupisa, nhoroondo dzekushandiswa kwayo mu bimetal thermocouples.Nzira dzekuita doping molybdenum poda ine potassium aluminosilicate kuti iwane isina-sag microstructure inofananidzwa neiyo tungsten yakagadziridzwa zvakare.
Iko kushandiswa kukuru kwe molybdenum sechinhu chinosanganisa simbi uye simbi yemidziyo, simbi isina tsvina, uye nickel-base kana cobalt-base super-alloys kuwedzera simba rinopisa, kusimba uye kusaita ngura.Mumaindasitiri emagetsi nemagetsi, molybdenum inoshandiswa mumacathodes, cathode inotsigira midziyo yeradar, ikozvino inotungamira yethorium cathodes, magnetron end hats, uye mandrels emhepo tungsten filaments.Molybdenum yakakosha muindasitiri yemakoni, uko inoshandiswa kune yakakwirira-tembiricha yezvimiro zvikamu, senge nozzles, inotungamira micheto yekudzora nzvimbo, tsigiro vanes, struts, reentry makoni, kuporesa-mwaranzi nhovo, kupisa singi, mavhiri eturbine, uye pombi. .Molybdenum yakabatsirawo mumaindasitiri enyukireya, makemikari, magirazi, uye ekugadzira simbi.Masevhisi tembiricha, ye molybdenum alloys mune zvimiro zvekushandisa arc, inogumira kune inokwana 1650°C (3000°F).Pure molybdenum ine kumira zvakanaka kuhydrochloric acid uye inoshandiswa kuita sevhisi yeasidhi mumaindasitiri emakemikari.
Molybdenum Alloy TZM
Iyo molybdenum alloy yekukosha kukuru kwetekinoroji ndeye yakakwirira-simba, yakakwirira-tembiricha alloy TZM.Izvo zvinhu zvinogadzirwa ingave neP/M kana arc-cast maitiro.
TZM ine tembiricha yepamusoro recrystallization uye simba repamusoro uye kuoma mukamuri uye patembiricha yakakwira kupfuura isina kurongeka molybdenum.Inoratidzawo ductility yakakwana.Yayo yepamusoro mechanical properties arc nekuda kwekupararira kwema carbides akaoma mumolybdenum matrix.TZM inonyatsokodzera kumabasa ekupisa nekuda kwekusanganiswa kwayo kwekuoma kwakanyanya kupisa, kukwira kwekushisa kwekushisa, uye kuwedzera kwekushisa kwepasi kune simbi dzinopisa.
Mashandisirwo Makuru Anosanganisira
Inofa inoisa yekukanda aluminium, magnesium, zinc, uye iron.
Rocket nozzles.
Kufa miviri uye zvibhakera nokuda kupisa stamping.
Zvishandiso zvesimbi (nekuda kwekunyanya abrasion uye chatter kuramba kweTZM).
Zvidziviriro zvekupisa zvevira, zvikamu zvechimiro, uye zvinhu zvekudziya.
Mukuedza kuvandudza simba repamusoro-tembiricha reP/M TZM alloys, alloys akagadzirwa umo titanium uye zirconium carbide inotsiviwa nehafnium carbide.Alloys e molybdenum ne rhenium ane ductile yakawanda pane pure molybdenum.Alloy ine 35% Re inogona kukungurutswa pakamuri tembiricha kusvika kudarika 95% kudzikiswa kwehukobvu isati yatsemuka.Nezvikonzero zvehupfumi, molybdenum-rhenium alloys haisi kushandiswa zvakanyanya mukutengesa.Alloys ye molybdenum ine 5 uye 41% Re inoshandiswa kune thermocouple waya.
