Imolybdenum ityiwa minyaka le kunayo nayiphi na enye intsimbi ephikisayo.Ii-ingots ze-Molybdenum, eziveliswa ngokunyibilika kwee-electrode ze-P/M, ziyakhutshelwa, ziqengqeleke zibe kwiphepha nakwintonga, zize emva koko zitsalwe kwezinye iimilo zemveliso yokusila, njengocingo kunye netyhubhu.Ezi zixhobo zinokuthi emva koko zigximfizwe kwiimo ezilula.I-Molybdenum iphinde yenziwe ngezixhobo eziqhelekileyo kwaye inokuba yigesi ye-tungsten arc kunye ne-electron beam edibeneyo, okanye ibrazed.I-Molybdenum inamandla abalaseleyo ombane kunye nokuqhuba ubushushu kunye nokomelela okuphezulu.I-Thermal conductivity imalunga ne-50% ephezulu kuneyentsimbi, isinyithi okanye i-nickel alloys.Ifumana ukusetyenziswa okubanzi njengeheatsinks.I-conductivity yayo yombane yeyona iphakamileyo kuzo zonke iintsimbi eziphikisayo, malunga nesinye kwisithathu sobhedu, kodwa siphezulu kune-nickel, iplatinum, okanye i-mercury.I-coefficient yokwandiswa kwe-thermal yeeplani ze-molybdenum phantse ngokuhambelana nobushushu kuluhlu olubanzi.Olu phawu, ngokudibeneyo luya kuphakamisa amandla okuqhuba ukushisa, i-akhawunti yokusetyenziswa kwayo kwi-bimetal thermocouples.Iindlela ze-doping molybdenum powder kunye ne-potassium aluminosilicate ukufumana i-microstructure engeyona i-sag enokuthelekiswa ne-tungsten nayo iye yaphuhliswa.
Ukusetyenziswa okukhulu kwe-molybdenum kufana ne-alloying agent ye-alloy kunye nezixhobo zensimbi, i-stainless steels, kunye ne-nickel-base okanye i-cobalt-base super-alloys ukunyusa amandla ashushu, ukuqina kunye nokuxhathisa ukubola.Kumashishini ombane kunye ne-elektroniki, i-molybdenum isetyenziswa kwii-cathodes, i-cathode ixhasa izixhobo ze-radar, i-current lead for thorium cathodes, i-magnetron end hats, kunye ne-mandrels yokujikeleza i-tungsten filaments.I-Molybdenum ibalulekile kwishishini lemijukujelwa, apho isetyenziselwa iindawo zezakhiwo ezinobushushu obuphezulu, njengemilomo, imiphetho ekhokelayo yendawo yokulawula, i-vanes yenkxaso, ii-struts, iicones zokuphinda zingene, izikhuselo zokupholisa-radiation, iisinki zobushushu, amavili einjini yomoya, kunye neepompo. .I-Molybdenum ikwaluncedo kwimizi-mveliso yenyukliya, yeekhemikhali, yeglasi kunye neyesinyithi.Ubushushu benkonzo, kwi-alloys ye-molybdenum kwi-arc ye-structural applications, bukhawulelwe kubuninzi obumalunga ne-1650 ° C (3000 ° F).I-molybdenum ecocekileyo inokumelana kakuhle ne-hydrochloric acid kwaye isetyenziselwa inkonzo ye-asidi kumashishini enkqubo yeekhemikhali.
Ingxubevange yeMolybdenum TZM
Ingxubevange ye-molybdenum ebaluleke kakhulu kwezobuchwephesha ngamandla aphezulu, ingxubevange yobushushu obuphezulu TZM.Izinto eziphathekayo zenziwe nge-P / M okanye iinkqubo ze-arc-cast.
I-TZM inobushushu obuphezulu bekristalis kunye namandla aphezulu kunye nobulukhuni kwigumbi kunye namaqondo obushushu aphezulu kune-molybdenum engafakwanga.Ikwabonisa i-ductility eyaneleyo.Iimpawu zayo eziphezulu zemishini i-arc ngenxa yokusabalalisa i-carbides eyinkimbinkimbi kwi-molybdenum matrix.I-TZM ifaneleka kakuhle kwimisebenzi eshushu ngenxa yokudityaniswa kwayo kokuqina okushushu okuphezulu, ukuhanjiswa okuphezulu kwe-thermal, kunye nokwandiswa kwe-thermal ephantsi kwiintsimbi zomsebenzi oshushu.
Usetyenziso olungundoqo lubandakanya
Iifakelo zokufa zokuphosa i-aluminium, i-magnesium, i-zinc, kunye nentsimbi.
Imilomo yerokhethi.
Yifa imizimba kunye neengqindi ngenxa yesitampu esishushu.
Izixhobo zokwenza isinyithi (ngenxa yokukrala okuphezulu kunye nokuxhathisa incoko ye-TZM).
Izikhuselo zobushushu kwiziko, iinxalenye zesakhiwo, kunye nezinto zokufudumeza.
Ngomzamo wokuphucula amandla aphezulu okushisa kwe-P / M TZM alloys, ii-alloys ziye zaphuhliswa apho i-titanium kunye ne-zirconium carbide ithathelwa indawo yi-hafnium carbide.I-alloys ye-molybdenum kunye ne-rhenium ininzi i-ductile kune-molybdenum ecocekileyo.I-alloy ene-35% Re inokuqengqeleka kwiqondo lobushushu begumbi ukuya ngaphezulu kwe-95% yokunciphisa ubukhulu ngaphambi kokuqhekeka.Ngenxa yezizathu zoqoqosho, i-molybdenum-rhenium alloys ayisetyenziswanga kakhulu kwintengiso.I-alloys ye-molybdenum ene-5 kunye ne-41% Re isetyenziselwa iingcingo ze-thermocouple.
