Ngokweziphumo zovavanyo lwe-electrochemical hydrogen permeation, ubukhulu bekhabhoni kunye neqhezu lomthamo we-carbides kwisampulu, incinci i-coefficient yokusasazwa kweeathom ze-hydrogen kunye nokunyibilika okukhulu. Njengoko umxholo wekhabhoni usanda, ukuchasana kwe-hydrogen embrittlement nako kuncipha.

Uvavanyo lwesantya soxinzelelo olucothayo luqinisekisile ukuba okukhona uphezulu umxholo wekhabhoni, kokukhona usezantsi ukuxhathisa koxinzelelo lwe-corrosion cracking. Ngokuhambelana neqhezu lomthamo we-carbides, njengoko ukusabela kokunciphisa i-hydrogen kunye nomthamo we-hydrogen ofakwe kwisampulu yokwanda kwesampulu, i-anodic dissolution reaction iya kwenzeka, kwaye ukubunjwa kwendawo yokutyibilika kuya kukhawuleziswa.

Xa umxholo wekhabhoni ukhula, i-carbides iya kudlula ngaphakathi kwentsimbi. Ngaphantsi kwesenzo se-electrochemical corrosion reaction, amathuba okuba ne-hydrogen embrittlement iya kwanda. Ukuze kuqinisekiswe ukuba intsimbi inokumelana ne-corrosion egqwesileyo kunye nokuchasana kwe-hydrogen embrittlement, i-carbide Precipitation kunye nokulawulwa kweqhekeza levolumu ziindlela ezisebenzayo zokulawula.

Ukusetyenziswa kwentsimbi kwiindawo ze-auto kuxhomekeke kwimida ethile, kwakhona ngenxa yokuncipha kwayo okukhulu ekuchaseni i-hydrogen embrittlement, ebangelwa yi-corrosion yamanzi. Enyanisweni, le nto ye-hydrogen embrittlement susceptibility ihambelana ngokusondeleyo nomxholo wekhabhoni, kunye nemvula ye-iron carbides (Fe2.4C / Fe3C) phantsi kweemeko eziphantsi kwe-hydrogen overvoltage.

Ngokuqhelekileyo, ngenxa yokusabela kwe-corrosion yendawo kwindawo ebangelwa yi-stress corrosion cracking phenomenon okanye i-hydrogen embrittlement phenomenon, uxinzelelo olushiyekileyo lususwa ngonyango lokushisa kunye nokusebenza kakuhle kwe-hydrogen trap. Akukho lula ukuphuhlisa intsimbi yeemoto ezinomgangatho ophezulu ophezulu kunye nokuxhathisa okugqwesileyo kokutya kunye nokumelana ne-hydrogen embrittlement.

Njengoko umxholo wekhabhoni usanda, izinga lokunciphisa i-hydrogen liyenyuka, ngelixa izinga lokusabalalisa i-hydrogen liyancipha kakhulu. Isitshixo sokusebenzisa i-carbon carbon okanye i-high carbon steel njengenxalenye okanye i-shafts yokuhambisa kukulawula ngokufanelekileyo amacandelo e-carbide kwi-microstructure.
