IFactory Price Thengisa iNiobium Powder ngeNb kunye neCAS No 7440-03-1 High-Entropy Alloys(HEA)

superalloy

Inxalenye enkulu ye-niobium yehlabathi isetyenziselwa ukuveliswa kwe-nickel, i-chromium kunye ne-iron-based superalloys kwifom ye-metallic ecocekileyo okanye ngendlela yococeko oluphezulu lwe-ferric niobium kunye ne-niobium nickel alloys. Ezi alloys zisetyenziswa kwii-jet engines, ii-injini ze-gas turbine, ii-rocket components, ii-turbocharger kunye nezixhobo zokutsha ezinganyangekiyo ubushushu. I-Niobium iya kwenza isigaba se-y kwisakhiwo sengqolowa ye-superalloy. Ezi alloys ngokubanzi ziqulathe ukuya kuthi ga kwi-6.5% niobium. I-Incone1718 alloy yenye ye-alloys esekelwe kwi-niobium-nickel, umxholo wento nganye: i-nickel 50%, i-chromium 18.6%, i-iron 18.5%, i-niobium 5%, i-key 3.1%, i-titanium 0.9% kunye ne-aluminium 0.4%. Izicelo zibandakanya njengempahla ye-airframe ephezulu, njengoko yayisetyenziswe kwiProjekthi yeGemini.

Isiseko se-Niobium ialloy

I-C-103 yi-alloy ye-niobium equlethe i-89% ye-niobium, i-10% ye-hafnium kunye ne-1% ye-titanium, enokusetyenziswa kwi-rocket propulsion nozzles, njenge-injini eyintloko yemodyuli yenyanga ye-Apollo. Imodyuli yenkonzo ye-Apollo isebenzise i-alloy yesilivere eyahlukileyo. Ekubeni i-niobium iqala i-oxidize ngaphezu kwe-400 ° C, ukuze ithintele ukuba ibe yi-brittle, i-coating yokukhusela kufuneka ifakwe kumphezulu wayo.

I-Niobium ikwadlala indima ebalulekileyo kunyango lotyando, ayinakusetyenziswa kuphela ukwenza izixhobo zonyango, kodwa ikwayinto elungileyo "yebhayoloji eguquguqukayo", kuba inokumelana nokugqwala okugqwesileyo, ayizukunxibelelana nezinto ezahlukeneyo zolwelo emzimbeni womntu. , kwaye phantse ngokupheleleyo ayilonakalisi izicubu zomzimba zebhayoloji, kuba naziphi na iindlela zokuvala inzala zinokuhlengahlengiswa. Ngoko inokubophelela kwizicubu zezinto eziphilayo ixesha elide kwaye ihlale ingenabungozi emzimbeni.
