Igiciro Cyiza Nb hamwe nibikoresho byiza bya mehaniki
Ibisobanuro
Niobium, bakunze kwita Nb, ni icyuma cyagaciro gikoreshwa cyane mubice bitandukanye nko kuvura, ikirere, n'inganda za kirimbuzi.Nibikoresho byiza cyane byubushyuhe bwo hejuru, byumuryango wibyuma byangiritse.
Ubwoko bumwe bwa niobium bukunze gukoreshwa ni ifu ya niobium, ikorwa mukugabanya okiside ya niobium mu itanura ryubushyuhe bwinshi.Ifu yavuyemo ni ifu nziza, yijimye-umukara ifu ifite isuku ryinshi, bigatuma ikoreshwa muburyo butandukanye.
Ifu ya Niobium ifite ibintu byinshi byingirakamaro, nkimbaraga nyinshi, guhindagurika neza, hamwe no kurwanya ruswa.Bikunze gukoreshwa mubikorwa byifu ya metallurgie, nkumusaruro wa superalloys, kubera aho ushonga cyane hamwe nubushobozi bwo kwihanganira ubushyuhe bwinshi nibidukikije bikaze.
Mu rwego rwubuvuzi, ifu ya niobium ikoreshwa mugukora imiti nubuvuzi bitewe na biocompatibilité hamwe nuburozi.Irakoreshwa kandi mugukora scaneri ya MRI kubera ubushobozi bwa magnetique bworoshye.
Mu nganda zo mu kirere, ifu ya niobium ikoreshwa mu gukora ibice bya moteri y’ubushyuhe bwo hejuru, nka rocket nozzles hamwe n’ingabo zikingira ubushyuhe, bitewe n’ingufu zayo nziza cyane ku buremere ndetse n’ubushobozi bwo guhangana n’ubushyuhe bwinshi n’ibidukikije byangirika.
Mu nganda za kirimbuzi, ifu ya niobium ikoreshwa mu gukora ibicanwa bya lisansi hamwe n’ibikoresho bya reaktor kubera ubushobozi bwayo bwo guhangana n’ubushyuhe bwinshi n’ibidukikije byangirika.
Muri rusange, ifu ya niobium ni ibintu byinshi kandi bifite agaciro bitanga ibintu bidasanzwe kandi birashobora gukoreshwa muburyo butandukanye bwo gusaba.
