Zvinoenderana nemhedzisiro yeye electrochemical hydrogen permeation test, iyo kabhoni yakakura uye vhoriyamu chikamu checarbides mumuenzaniso, kudiki kweiyo diffusion coefficient yemaatomu ehydrogen uye kunyungudika kukuru. Sezvo iyo kabhoni yemukati inowedzera, kuramba kune hydrogen embrittlement zvakare kunoderera.

Slow strain rate rate tensile test yakasimbisa kuti iyo yakakwira kabhoni yemukati, inodzikisira kushushikana kwecorrosion kupaza kuramba. Proportional kune chikamu chevhoriyamu yecarbides, seye hydrogen yekudzikisa maitiro uye huwandu hwehydrogen jekiseni mukuwedzera kwemuenzaniso, iyo anodic dissolution reaction ichaitika, uye kuumbwa kwenzvimbo inotsvedza kuchawedzerwawo.

Kana iyo kabhoni yemukati ichiwedzera, carbides inonaya mukati mesimbi. Pasi pechiito che electrochemical corrosion reaction, mukana wehydrogen embrittlement uchawedzera. Kuti ive nechokwadi chekuti simbi ine yakanakisa corrosion resistance uye hydrogen embrittlement resistance, iyo carbide Precipitation uye vhoriyamu chikamu chekudzora inzira dzinoshanda dzekudzora.

Iko kushandiswa kwesimbi muzvikamu zvemotokari kunoenderana nezvimwe zvisingakwanisi, zvakare nekuda kwekuderera kwayo kukuru mukupokana nehydrogen embrittlement, iyo inokonzerwa neaqueous corrosion. Muchokwadi, iyi hydrogen embrittlement susceptibility inowirirana zvakanyanya nekabhoni yemukati, nekunaya kwesimbi carbides (Fe2.4C/Fe3C) pasi peyakaderera hydrogen overvoltage mamiriro.

Kazhinji, nokuda kwenzvimbo yekugara kwegorosi pamusoro pepamusoro inokonzerwa nekushungurudzika kwekuputika kwekuputika chiitiko kana hydrogen embrittlement phenomenon, kushushikana kwakasara kunobviswa nekupisa kupisa uye hydrogen trap kunyatsoshanda inowedzera. Hazvisi nyore kugadzira simbi yepamusoro-yepamusoro-yakasimba yemotokari ine zvese zvakanakisa corrosion resistance uye hydrogen embrittlement kuramba.

Sezvo iyo kabhoni yemukati inowedzera, mwero wekudzikisa hydrogen unowedzera, nepo hydrogen diffusion rate inoderera zvakanyanya. Kiyi yekushandisa yepakati kabhoni kana yakakwira kabhoni simbi sezvikamu kana kutapurirana shafts ndeyekunyatso kudzora zvikamu zvecarbide mune microstructure.
