Farashin masana'anta Siyar da foda na Niobium tare da Nb da CAS No 7440-03-1 High-Entropy Alloys (HEA)

superalloy

Ana amfani da babban kaso na niobium na duniya wajen samar da nickel, chromium da baƙin ƙarfe na tushen superalloys a cikin tsantsar ƙarfe mai tsafta ko kuma a cikin sigar babban tsafta ferric niobium da niobium nickel gami. Ana amfani da waɗannan allunan a cikin injunan jet, injin injin turbin gas, kayan aikin roka, caja da na'urorin konewa masu jure zafi. Niobium zai samar da lokaci na y a cikin tsarin hatsi na superalloy. Waɗannan gami gabaɗaya sun ƙunshi har zuwa 6.5% niobium. Incone1718 alloy yana daya daga cikin niobium-nickel tushen gami, abun ciki na kowane kashi shine: nickel 50%, chromium 18.6%, iron 18.5%, niobium 5%, key 3.1%, titanium 0.9% da aluminum 0.4%. Aikace-aikace sun haɗa a matsayin babban kayan aikin iska, kamar wanda aka yi amfani da shi a cikin Project Gemini.

Niobium tushe gami

C-103 niobium gami ne mai dauke da 89% niobium, 10% hafnium da 1% titanium, wanda za a iya amfani da shi a cikin ruwa roka propulsion nozzles, kamar babban engine na Apollo Lunar module. Sabis ɗin sabis na Apollo ya yi amfani da gawa na azurfa daban-daban. Tun da niobium ya fara yin oxidize sama da 400 ° C, don hana shi zama gaggautsa, dole ne a sanya murfin kariya a samansa.

Niobium kuma yana taka muhimmiyar rawa wajen yin aikin tiyata, ba za a iya amfani da shi kawai don kera na'urorin likitanci ba, har ma yana da kyau "kayan daidaita dabi'un halitta", saboda yana da kyakkyawan juriya na lalata, ba zai yi hulɗa da abubuwa daban-daban na ruwa a cikin jikin mutum ba. , kuma kusan gaba daya baya lalata kyallen jikin kwayoyin halitta, don kowane hanyoyin haifuwa ana iya daidaita su. Don haka yana iya ɗaure jikin kwayoyin halitta na dogon lokaci kuma ya kasance cikin jiki ba tare da lahani ba.
