Izinsimbi eziqinile eziphakeme zizokhiqiza ukucwebezela lapho zifakwe uthayela. Udinga ukunakwa okukhethekile.
I-hydrogen embrittlement ngokuvamile ibonakala ngokuphuka kwesikhashana ngaphansi kwengcindezi. Kube khona iziphethu zezimoto, amawasha, izikulufu, iziphethu zeshidi nezinye izingxenye zikathayela, emahoreni ambalwa ngemva kokwephulwa komhlangano, isilinganiso sokuphuka singu-40% ~ 50%. Enqubweni yokusebenzisa izingxenye ze-cadmium-plated zomkhiqizo okhethekile, kwaba nokuqhekeka kwe-batch crack, futhi inkinga yokhiye kazwelonke yaxazululwa futhi kwenziwa inqubo eqinile ye-dehydrogenation. Ngaphezu kwalokho, kukhona ezinye embrittlement hydrogen akubonisi ukubambezeleka mkhuba ukuphuka, ezifana: electroplating isiphanyeko (insimbi yensimbi, ucingo lwethusi) ngenxa izikhathi eziningi electroplating futhi pickling plating, hydrogen Ukungena kubi kakhulu, ngokuvamile avele ukusetshenziswa fold kwenzeka i-brittle fracture phenomenon; I-mandrel ye-shotgun, ngemva kwezikhathi eziningana ze-chroming, yawela phansi futhi yaphuka; Ezinye izingxenye ezicishiwe (ukucindezeleka okukhulu kwangaphakathi) zizoqhekeka lapho zikhetha. Lezi zingxenye zine-hydrogenated kakhulu futhi ziyaqhekeka ngaphandle kokucindezeleka kwangaphandle, ezingasakwazi ukusetshenziselwa ukubuyisela ukuqina kwangempela nge-dehydrogenation.
Ukuphakama kwamandla ezinto ezibonakalayo, kukhulu ukuzwela kwe-hydrogen embrittlement. Lona umqondo oyisisekelo okufanele ucaciswe ochwepheshe bokwelapha okungaphezulu lapho behlanganisa imininingwane yenqubo ye-electroplating. Izinsimbi ezinamandla aqinile σb>105kg/mm2 ezidingwa izindinganiso zamazwe ngamazwe kufanele zibe ngaphansi kwengcindezi yangaphambi kokucwenga kanye nokwelashwa kwe-post-plating dehydrogenation ngokufanele. Imboni yezokundiza yaseFrance idinga ukwelashwa okuhambisanayo kwe-dehydrogenation ezingxenyeni zensimbi ezinamandla okukhiqiza angu-σs>90kg/mm2.
Ngenxa yokuxhumana okuhle phakathi kwamandla ensimbi nobulukhuni, kunembile futhi kulula ukwahlulela ukuzwela kwe-hydrogen embrittlement yezinto ngobulukhuni kunamandla. Ngoba umdwebo womkhiqizo ophelele kanye nenqubo yokwenza imishini kufanele imakwe ngobulukhuni bensimbi. Ku-electroplating, sithole ukuthi ubulukhuni bensimbi ezungeze i-HRC38 buqale ukukhombisa ubungozi bokuphuka kwe-hydrogen embrittlement. Ezingxenyeni ezingaphezulu kune-HRC43, ukukhishwa kwe-hydrogen kufanele kucatshangelwe ngemva kokucwetshwa. Uma ubulukhuni bucishe bube yi-HRC60, ukwelashwa kwe-dehydrogenation kufanele kwenziwe ngokushesha ngemva kokwelashwa kwendawo, ngaphandle kwalokho izingxenye zensimbi zizoqhekeka phakathi namahora ambalwa.
* Umdwebo olandelayo ukhomba ama-incoterms ohwebo ahlukene. Sicela ukhethe oyithandayo.
