Izibophelelo zokuqina eziphezulu ziya kuvelisa ukuqaqamba xa zifakwe igalvanized.Kufuneka ingqalelo ekhethekileyo.

I-Hydrogen embrittlement idla ngokubonakaliswa ngokulibaziseka ukuphuka phantsi koxinzelelo.Kubekho imithombo yemoto, iiwasha, izikrufu, izithonga zamashiti kunye nezinye iindawo ezifakwe amazimba, kwiiyure ezimbalwa emva kokuba indibano yaphukile, umlinganiselo wokwaphuka wama-40% ~ 50%.Kwinkqubo yokusebenzisa iinxalenye ze-cadmium-plated zemveliso ekhethekileyo, kwakukho i-batch crack fracture, kwaye ingxaki engundoqo yelizwe yasonjululwa kwaye inkqubo engqongqo ye-dehydrogenation yenziwe.Ukongeza, kukho ezinye i-hydrogen embrittlement ayibonisi isenzeko sokulibaziseka kokwaphuka, okufana: i-electroplating hanger (intambo yentsimbi, ucingo lobhedu) ngenxa yamaxesha amaninzi e-electroplating kunye ne-pickling plating, ukungena kwe-hydrogen kubi kakhulu, kaninzi kubonakala xa kusetyenziswa isibaya. kwenzeke into eyenzeka ngokuqhekeka;I-mandrel yompu, emva kwamaxesha amaninzi e-chroming, yawa phantsi yaza yaphuka;Ezinye iindawo ezicinyiweyo (uxinzelelo olukhulu lwangaphakathi) ziya kuqhekeka xa zikhetha.Ezi nxalenye zine-hydrogenated kakhulu kwaye ziqhekeka ngaphandle koxinzelelo lwangaphandle, olungasayi kuphinda lusetyenziswe ukubuyisela ubunzima bokuqala nge-dehydrogenation.

Ukuphakama kwamandla ezinto eziphathekayo, lukhulu uvakalelo lwe-hydrogen embrittlement.Le ngcamango esisiseko ekufuneka icaciswe ngabachwephesha bonyango lomphezulu xa bequlunqa iinkcukacha zenkqubo ye-electroplating.Iintsimbi ezinamandla okuqina σb>105kg/mm2 ezifunwa yimigangatho yamazwe ngamazwe kufuneka zibe phantsi koxinzelelo lwangaphambili kunye nonyango lwe-post-plating dehydrogenation ngokufanelekileyo.Ishishini lenqwelomoya laseFransi lifuna unyango oluhambelanayo lwe-dehydrogenation kumalungu entsimbi anamandla esivuno σs>90kg/mm2.

Ngenxa yembalelwano elungileyo phakathi kokuqina kwentsimbi kunye nokuqina, kuyaqondakala kwaye kulula ukugweba uvakalelo lwe-hydrogen embrittlement yezinto ngobulukhuni kunokuba ngamandla.Ngenxa yokuba umzobo ogqibeleleyo wemveliso kunye nenkqubo yomatshini kufuneka imakwe ngobulukhuni bentsimbi.Kwi-electroplating, safumanisa ukuba ukuqina kwentsimbi ejikeleze i-HRC38 yaqala ukubonisa umngcipheko wokuqhekeka kwe-hydrogen embrittlement.Kwiindawo ezingaphezulu kune-HRC43, i-dehydrogenation kufuneka ithathelwe ingqalelo emva kokubekwa.Xa ukuqina malunga ne-HRC60, unyango lwe-dehydrogenation kufuneka lwenziwe ngokukhawuleza emva konyango lwangaphezulu, ngaphandle koko iindawo zentsimbi ziya kuqhekeka kwiiyure ezimbalwa.
