Kugirango imbaraga zishoboke, karubone nayo igomba kongerwamo ibyuma, hamwe na karubide yicyuma. Urebye amashanyarazi, karbide yicyuma ikora nka cathode, byihutisha reaction ya anodic reaction hafi ya substrate. Ubwiyongere bw'igice cya karbide ya fer muri microstructure nayo iterwa na hydrogène nkeya ya volvoltage ya karbide.

Ubuso bwibyuma biroroshye kubyara no gukuramo hydrogen. Iyo atome ya hydrogène yinjiye mu byuma, igice kinini cya hydrogène gishobora kwiyongera, hanyuma amaherezo yo kurwanya hydrogène yinjira mu bikoresho bikagabanuka cyane.

Kugabanuka gukabije kwangirika kwangirika hamwe no kurwanya hydrogène irwanya ibyuma bikomeye cyane ntabwo byangiza imiterere yicyuma gusa, ahubwo binagabanya cyane ikoreshwa ryibyuma.

Kurugero, mugihe ibyuma byimodoka bihuye nibidukikije byangirika nka chloride, mugihe cyibikorwa bya stress, ibintu byo guturika kwangirika (SCC) bishobora kubaho bishobora guhungabanya umutekano wumubiri wimodoka.

Iyo karubone irenze, niko coefficient de hydrogène ikwirakwizwa kandi niko hydrogène ikomera. Intiti Chan yigeze gusaba ko inenge zinyuranye zimeze nk'imvura (nk'umutego wa atome ya hydrogène), ibishoboka, hamwe na pore bigereranywa n'ibirimo karubone. Ubwiyongere bwibintu bya karubone bizabuza ikwirakwizwa rya hydrogène, bityo coefficient ya hydrogène nayo iri hasi.

Kubera ko ibirimo bya karubone bigereranywa na hydrogène solubilité, niko igice kinini cyigice cya karbide nkumutego wa hydrogène atom, umuto muto wa hydrogène ukwirakwiza imbere mu byuma, niko hydrogène ikomera, hamwe na hydrogène solubile nayo ikubiyemo amakuru ajyanye na hydrogène ikwirakwizwa, Hydrogen rero embrittlement susceptibility niyo isumba izindi. Hamwe no kwiyongera kwa karubone, coefficient de diffuzione ya atome ya hydrogène iragabanuka kandi hejuru ya hydrogène yo hejuru yiyongera, ibyo bikaba biterwa no kugabanuka kwa hydrogène irenze hejuru yicyuma.
