Uyu munsi, imiyoboro yicyuma ifite ibicuruzwa byinshi bigurishwa ku isoko buri mwaka ku isoko ryibyuma. Urebye tekinoroji yo gutunganya umusaruro, umuyoboro wa galvanise ugabanijwemo ubwoko bubiri: umuyoboro w'amashanyarazi wa elegitoronike n'umuyoboro ushushe. Mubuzima, abantu muri rusange bakunze kwita umuyoboro ushyushye wavanze nkumuyoboro wa galvanis. Mu magambo make, umuyoboro ushyushye wa galvanized umuyoboro ufite ibyiza byo gukora kuruta umuyoboro wa electro. Uretse ibyo, kubera ibiciro byo gutunganya byinshi, igiciro cyumuyoboro wicyuma gihenze gato ugereranije nu muyoboro w'amashanyarazi. Nkuko bisanzwe, iyo ugereranije numuyoboro ushyushye ushyizwemo umuyoboro wibyuma, umuyoboro wicyuma urukiramende ntabwo ufite umutungo mwiza muri rusange, cyane cyane umutungo wo kurwanya ruswa. Mu myaka yashize, kubera politiki y'igihugu, umuyoboro w'amashanyarazi wavanyweho ku isoko ry'ibyuma.
Ku bijyanye n'umuyoboro wa galvanis, tugomba kumenya kubyerekeye ijambo "galvanisation". Umuyoboro ushyushye ushyizwemo ibyuma bizashyirwa mu bikorwa aho hazaba hashyizweho urwego ruvanze n’imiyoboro bitewe n’imikorere igaragara hagati ya zinc yashongeshejwe nicyuma. Nkigisubizo, ubu bwoko bwumuyoboro bufite imbaraga zo kurwanya ruswa kurusha ubundi bwoko busanzwe. Byongeye kandi, umuyoboro wibyuma ufite igifuniko kimwe cyane hamwe nu mutungo ukomeye wa zinc layer kugirango wongere igihe kinini cyimirimo yimiyoboro. Ikigeretse kuri ibyo, ugereranije nindi miyoboro ikunze kugaragara, umuyoboro ushyushye ushyizwemo ibyuma bifite ibyuma byinshi bigaragara muburyo butandukanye mubuzima.
Muburyo bwa tekiniki, galvanisation ifitanye isano no gukoresha zinc ikingira umubiri wicyuma cyangwa umuyoboro wicyuma, kugirango wirinde ingese. Gallvanizing ishyushye nuburyo bukunze kugaragara bwa galvanisiyasi, aho imibiri yimiyoboro irohama mu bwogero bwa zinc yashonze. Muri rusange, ukurikije ibikoresho fatizo by'imiyoboro, umuyoboro wa galvanis ufite ibyiciro bibiri: umuyoboro wa pre-galvanised hamwe n'umuyoboro w'icyuma ushyushye. Umuyoboro wateguwe mbere yerekana umuyoboro wogoswe wagiye ugabanuka, kuvanaho ingese, fosifori, no gukama mbere yo gusya. Ubuvuzi mbere ya galvanisiyasi butuma ibicuruzwa bishyirwa muburyo bworoshye hamwe na zinc, kandi bikanemeza ko umubyimba umwe wuzuye, gufatana gukomeye, no kunoza ruswa. Imiyoboro yabanje gukoreshwa ikoreshwa cyane muri sisitemu yo gutanga ubushyuhe, amazi na gazi karemano, umurima wubuhinzi bwa pariki yubuhinzi, ubwubatsi bwibyuma byubatswe kimwe na sisitemu yo kuvoma ingufu nke kandi ziciriritse.
