E hana nā mea paʻa ikaika kiʻekiʻe i ka crispness i ka wā e gitanized. Pono i ka nānā kūikawā.

ʻO ka hydrogen embritmentment e hōʻikeʻia e ka lohiʻana i ke kaumaha ma lalo o ke kaumaha. Loaʻa nā pūnāwai Automobile,ʻo Warhers, SCrews I ke kaʻina o ka hoʻohanaʻana i nā'āpana cadmium-i hoʻopaʻaʻia i kahi huahana kūikawā, aia ka pā o ka pākeke i hoʻopaʻaʻia a he kaʻina hana he nui. Eia kekahi, aia kekahi mau hydrogen embrittlement e hōʻike ana i ka manawaleʻa, e like me nā mea kūʻai aku,ʻoi aku ka nui e hana i nā brittle blueledon; Ka mandrel o kahi pana, ma hope o nā manawa o kaʻohiʻana, hāʻule i ka lepo a ua wāwahiʻia; ʻO kekahi mau'āpana helu (koʻikoʻi nui i loko o ke kaumaha) e pale i ka wā eʻohiʻia ai. ʻO kēia mau'āpana he hydrogenated hydrogenated a me ka crack me ke kaumahaʻole,ʻaʻole hiki ke hoʻohana houʻia e hoʻihoʻi hou i ka paʻakikī o ka dehydrogen.

ʻOi aku ka kiʻekiʻe o ka ikaika o ka waiwai,ʻoi aku ka nui o ka hydrogen embrittlement. ʻO kēia kahi manaʻo pilikino e pono ke weheweheʻia e nā loea hana hana i ka wā e hoʻopili ai i nā kiko'ī e pili ana i nā kiko'ī. ʻO nā mea hele me ka ikaika o ka maʻi thinsile σb> 105kg / mm2 i koiʻia e nā hana kūpono e like me keʻano o ka mālamaʻana i keʻano. Pono kaʻoihana hana kūʻai akuʻo Farani e pili ana i ka hana hana dehydrogonation no nā'āpana kila me nā mea e hāʻawi ai i ka ikaika σs> 90kg / mm2.

Ma muli o ka pili maikaʻi ma waena o ka ikaika kila a me ka paʻakikī,ʻoi aku ka maʻalahi a me ka maʻalahi e hoʻoponopono i ka mea paʻakikī ma mua o ka ikaika o ka hydrogen No ka mea,ʻo kahi kiʻi kiʻi kiʻi kūpono a me ke kaʻina hana e pono ai e hōʻailonaʻia me ka paʻakikī paʻakikī. I ka electrplating, uaʻike mākou ua loaʻa ka paʻakikī o ke kila a puni ka HRC38 e hōʻike i ka pilikia o ka hydrogen embrittlement. No nā'āpana kiʻekiʻe ma mua o HRC43, e noʻonoʻoʻia ka dehydrogonation ma hope o ka hoʻopauʻana. Ke pili nei ka paʻakikī o HRC60
