Bitewe n’ibiciro mpuzamahanga by’amabuye y’agaciro, igiciro cy’ibyuma bishaje cyariyongereye cyane ndetse n’igiciro cy’ibyuma by’ingurube gitangira kuzamuka. Nanone kurengera ibidukikije bigira ingaruka ku kuba ibikoresho byo mu rwego rwo hejuru bya carburizing nta kintu na kimwe bihari. Hanyuma igiciro cy’ibyuma bishobora kuzamuka mu kwezi gutaha. Dore ibi bikurikira:
1 Icuma cy'ingurube na coke
Nubwo ibyuma byoherezwa mu turere duto, muri Shanxi, Jiangsu, Hebei, Henan n'utundi turere nubwo ibyuma bicuruzwa ari bike, ariko hari inganda nke cyane zikora bityo ububiko si bwinshi. Izamuka ry'isoko ry'ibyuma, ibiciro bya coke n'amabuye y'agaciro bigira ingaruka ku ibiciro by'ibyuma byazamutse, mu cyumweru gishize ibyuma by'ingurube byazamutseho 1%- 3%, coke yazamutseho 2% kandi ububiko bwombi bwaragabanutse. Ingufu z'impeshyi ziraza, icyifuzo n'igiciro cya coke bizakomeza kwiyongera. Ariko bitewe n'ubushyuhe bwinshi n'igihe kitari cyiza, icyifuzo cy'ibyuma n'inganda zikora ibyuma by'ingurube ntikirushaho kuba cyiza, byitezwe ko igiciro kizongera cyane mu gihe gito.
2 Ibikoresho byo gusiga ibyuma n'ibisigazwa by'amavuta
Icupa ry'uruganda rwakuweho kubera ibibazo by'ibidukikije, amasosiyete menshi yatangiye guhindura uburyo bwo gushonga itanura hakoreshejwe amashanyarazi, akoresha ibyuma bito kandi bikoreshwa mu kongera gukoresha ibyuma bisya n'ibisigazwa kugira ngo akore icyuma gishyushye cyangwa icyuma cy'umukara. Icupa rya grafiti ni ingenzi, ariko mu gice cya mbere cy'umwaka, kurengera ibidukikije byatumye inganda nyinshi zifungwa kandi icupa rya carburizing ribura. Ikindi kandi, ibiciro by'ibisigazwa byarazamutse cyane ku buryo ikiguzi cy'inganda cyariyongereye kandi igiciro cy'imiyoboro y'ibyuma n'ibikoresho byo gushushanya nacyo gishobora kwiyongera.
