Ibyuma byombi bivanze nicyuma cya karubone bifite akamaro kanini.Ibyuma bya karubone ni uruvange rwicyuma na karubone, mubisanzwe birimo karubone igera kuri 2% kuburemere.Bikunze gukoreshwa mubikorwa: imashini, ibikoresho, ibyuma byuma, ibiraro nibindi bikorwa remezo.Kurundi ruhande, ibyuma bivanze ni ubwoko bwibyuma birimo ikintu kimwe cyangwa byinshi bivanga (mubisanzwe manganese, chromium, nikel nibindi byuma) hiyongereyeho karubone.Ibyuma bivangavanze bikunze gukoreshwa mubice bikomeye cyane nka gare, shitingi na axe.
Icyuma cya karubone ni iki?
Ibyuma bya karubone nicyuma gifite karubone nkibintu nyamukuru bivangwa.Ubusanzwe ifite karubone irenze ibyuma bivanze.Ibyuma bya karubone bikoreshwa muburyo butandukanye, harimo ibice byimodoka, ibikoresho byubaka nibikoresho byamaboko.Azwiho imbaraga nigihe kirekire, kandi irashobora kuvurwa ubushyuhe kugirango yongere ubukana bwayo.Ibyuma bya karubone nabyo bikunda kwangirika kuruta ubundi bwoko bwibyuma.Ibice by'ibyuma bya karubone birashobora gukorwa muguhimba, guta no gutunganya.
Icyuma kivanze ni iki?
Alloy ibyuma ni ubwoko bwibyuma birimo ibintu bivanze (nka aluminium, chromium, umuringa, manganese, nikel, silicon na titanium) hiyongereyeho karubone mubyuma bisanzwe bya karubone.Ibi bintu bivangavanze bitezimbere imiterere yicyuma.Amavuta amwe amwe yarateye imbere: imbaraga, gukomera, kwambara birwanya no / cyangwa kurwanya ruswa.Amashanyarazi akoreshwa cyane mu bikorwa bitandukanye, cyane cyane mu bwubatsi, mu modoka no mu kirere.
Ni ubuhe bwoko butandukanye bw'ibyuma bivanze?
Mubisanzwe, urashobora kugabanya ibyuma bivangavanze muburyo bubiri (2) butandukanye: ibyuma bito bito hamwe nicyuma kinini.
Icyuma gike cyane bivuga ibyuma bivanze hamwe nibintu bimwe bivanga munsi ya 8%.Ikintu cyose kirenze 8% gifatwa nkicyuma kinini.
Nubwo ushobora gutekereza ko ibyuma birebire cyane bikunze kugaragara, mubyukuri, ni ikinyuranyo.Icyuma giciriritse cyane kiracyari ubwoko bwibyuma bivangwa kumasoko muri iki gihe.
