Ixabiso leMetal Nb elineempawu ezigqwesileyo zoomatshini
Inkcazo
I-Niobium, edla ngokubizwa ngokuba yi-Nb, yintsimbi exabisekileyo esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana nonyango lwezonyango, i-aerospace, kunye neshishini lenyukliya.Yeyona nto ibalaseleyo yolwakhiwo lobushushu obuphezulu, eyeyentsapho yeentsimbi eziphikisayo.
Olunye uhlobo lwe-niobium olusetyenziswa ngokuqhelekileyo ngumgubo we-niobium, oveliswa ngokunciphisa i-niobium oxide kwisithando somlilo esiphezulu.I-powder ephumelayo iyimpuphu ecocekileyo, e-greyish-black kunye namanqanaba aphezulu okucoceka, okwenza ukuba ifaneleke kwizicelo ezahlukeneyo.
I-Niobium powder ineepropathi ezininzi eziluncedo, ezinje ngokuqina okuphezulu, i-ductility elungileyo, kunye nokumelana nokugqwesa okugqwesileyo.Ihlala isetyenziswa kwi-powder metallurgy applications, njengokuveliswa kwe-superalloys, ngenxa yendawo ephezulu yokunyibilika kunye nokukwazi ukumelana nokushisa okuphezulu kunye neendawo ezinzima.
Kwicandelo lezonyango, i-niobium powder isetyenziselwa ukuvelisa izixhobo zonyango kunye nezixhobo ngenxa ye-biocompatibility yayo kunye ne-non-toxicity.Ikwasetyenziselwa ukuveliswa kweeskena ze-MRI ngenxa yokungabi namandla kwamagnetic.
Kwishishini le-aerospace, i-niobium powder isetyenziselwa ukuvelisa iinxalenye ze-injini zobushushu obuphezulu, ezifana ne-rocket nozzles kunye nezikhuselo zokushisa, ngenxa yomlinganiselo wayo obalaseleyo wobunzima kunye nokukwazi ukumelana nokushisa okuphezulu kunye neendawo ezinobungozi.
Kwishishini lenyukliya, i-niobium powder isetyenziselwa ukuveliswa kweentonga zamafutha kunye namacandelo e-reactor ngenxa yokukwazi ukumelana nokushisa okuphezulu kunye neendawo ezinobungozi.
Ngokubanzi, i-niobium powder yinto eguquguqukayo kwaye ixabisekileyo enika iimpawu ezikhethekileyo kwaye ingasetyenziselwa uluhlu olubanzi lwezicelo.
