Ngokwemiphumela yokuhlolwa kwe-electrochemical hydrogen permeation, uma kukhulu okuqukethwe kwekhabhoni kanye nengxenye yevolumu ye-carbides kusampula, kuba kuncane kwe-coefficient yokusabalalisa yama-athomu e-hydrogen kanye nokuncibilika okukhulu. Njengoba okuqukethwe kwekhabhoni kwanda, ukumelana ne-hydrogen embrittlement nakho kuncipha.

Ukuhlolwa okunensayo kwesilinganiso sokuqina kwengcindezi kuqinisekisile ukuthi ukuphakama kwekhabhoni, kuyancipha ukumelana nokuqhekeka kokugqwala kwengcindezi. Ngokuhambisana nengxenye yevolumu ye-carbides, njengoba ukusabela kokunciphisa i-hydrogen kanye nenani le-hydrogen elijovwe ekukhuleni kwesampula, ukusabela kokuqedwa kwe-anodic kuzokwenzeka, futhi ukwakheka kwendawo yokushelela nakho kuzosheshiswa.

Lapho okuqukethwe kwekhabhoni kukhuphuka, ama-carbides azogcwala ngaphakathi kwensimbi. Ngaphansi kwesenzo sokusabela kwe-electrochemical corrosion, kungenzeka ukuthi i-hydrogen embrittlement ikhule. Ukuze kuqinisekiswe ukuthi insimbi inokumelana nokugqwala okuhle kakhulu kanye nokumelana ne-hydrogen embrittlement, i-carbide Precipitation kanye nokulawula ingxenyena yevolumu kuyindlela yokulawula ephumelelayo.

Ukusetshenziswa kwensimbi ezingxenyeni zezimoto kungaphansi kwemikhawulo ethile, futhi ngenxa yokuncipha kwayo okuphawulekayo kokumelana ne-hydrogen embrittlement, okubangelwa ukugqwala kwamanzi. Eqinisweni, lokhu kuthambekela kwe-hydrogen embrittlement kuhlobene eduze nokuqukethwe kwekhabhoni, nemvula yama-iron carbides (Fe2.4C/Fe3C) ngaphansi kwezimo eziphansi ze-hydrogen overvoltage.

Ngokuvamile, ngenxa yokusabela kokugqwala kwendawo okubangelwa ukugqwala kwe-stress corrosion cracking noma i-hydrogen embrittlement phenomenon, ukucindezeleka okusalayo kususwa ukwelashwa kokushisa kanye nokusebenza kahle kwe-hydrogen trap. Akulula ukwakha insimbi yezimoto enamandla kakhulu enokumelana nokugqwala okuhle kakhulu kanye nokumelana ne-hydrogen embrittlement.

Njengoba okuqukethwe kwekhabhoni kukhula, izinga lokunciphisa i-hydrogen liyakhula, kuyilapho izinga lokusatshalaliswa kwe-hydrogen lehla kakhulu. Isihluthulelo sokusebenzisa i-carbon medium noma i-high carbon steel njengezingxenye noma ama-transmission shafts ukulawula ngempumelelo izingxenye ze-carbide ku-microstructure.
