Inkcazo yeenkcukacha

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 isiganeko sokuqhekeka kwamathambo; 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.
