Ukurikije ibisubizo by’ikizamini cy’amashanyarazi ya hydrogène y’amashanyarazi, niko ibyinshi bya karubone hamwe n’igice cy’ibice bya karbide mu cyitegererezo, ni ko coefficient de diffuzione ya atome ya hydrogène iba nini kandi ikaboneka cyane. Mugihe imyuka ya karubone yiyongera, kurwanya hydrogène nayo igabanuka.

Kwipimisha gahoro gahoro kwipimisha byemeje ko uko karubone irenze, niko kugabanuka kwangirika kwangirika. Ugereranije nubunini bwigice cya karbide, nkuko reaction ya hydrogène igabanuka nubunini bwa hydrogène yatewe muri sample byiyongera, reaction ya anodic reaction izabaho, kandi no gushiraho akarere kanyerera nabyo bizihuta.

Iyo karubone yiyongereye, karbide zizagwa imbere mubyuma. Mugihe cyibikorwa bya electrochemic corrosion reaction, amahirwe yo kwinjiza hydrogène aziyongera. Kugirango hamenyekane neza ko ibyuma bifite imbaraga zo kurwanya ruswa no kurwanya hydrogène, irwanya imvura ya Carbide no kugenzura ibice ni uburyo bwiza bwo kugenzura.

Gukoresha ibyuma mubice byimodoka biterwa nimbogamizi zimwe na zimwe, nanone bitewe nigabanuka ryinshi ryurwanya hydrogène yinjira, iterwa no kwangirika kwamazi. Mubyukuri, iyi hydrogène yoroha cyane ifitanye isano rya hafi na karubone, hamwe n’imvura ya karubide yicyuma (Fe2.4C / Fe3C) mugihe cya hydrogène nkeya.

Mubisanzwe, kubijyanye no kwangirika kwangirika hejuru yubutaka biterwa no guhangayika kwangirika kwangirika cyangwa hydrogène embrittlement phenomenon, imihangayiko isigaye ikurwaho no kuvura ubushyuhe kandi imikorere ya hydrogène imitego iriyongera. Ntibyoroshye guteza imbere imbaraga-zidasanzwe-zifite ibyuma byimodoka bifite imbaraga zo kurwanya ruswa ndetse no kurwanya hydrogène.

Mugihe karubone yiyongera, igipimo cyo kugabanya hydrogène cyiyongera, mugihe ikwirakwizwa rya hydrogène rigabanuka cyane. Urufunguzo rwo gukoresha karubone yo hagati cyangwa ibyuma birebire bya karubone nkibice cyangwa imiyoboro yohereza ni ukugenzura neza ibice bya karbide muri microstructure ..
