Imininingwane yemininingwane
Ama-fasteners anamandla aphezulu azokhiqiza ubumnyama lapho egaywe. Dinga ukunakwa okukhethekile.
I-Hydrogen Embrittlement imvamisa ibonakala ngokubambezeleka kokuqhekeka ngaphansi kwengcindezi. Kube khona iziphethu zezimoto, ama-washers, ama-screws, iziphethu zephepha kanye nezinye izingxenye ezigayiwe, emahoreni ambalwa ngemuva komhlangano aphulwe, ingxenye ye-40% ~ 50%. Esezinhlelweni zokusebenzisa izingxenye ze-cadmium-plated zomkhiqizo okhethekile, kwakukhona ukuqhekeka kwe-batch crackuw, futhi inkinga kazwelonke yenzelwe okuxazululwa futhi inqubo eqinile ye-dehydrogenation yakhiwa. Ngaphezu kwalokho, kunezinye izindlela ze-hydrogen ezingabonisi into ebambezelekile ye-Fracture, njenge: Electroplating Hanger Hannger (wire yensimbi, ukungena kwensimbi) Ngenxa yezikhathi eziningi ze-electroplating kanye nokuthathwa kwe-hydrogen, kubukeka sengathi kusetshenziswa i-fold will zenzeke nge-brittle gracture phenomenon; Ummeli wesibhamu, ngemuva kwezikhathi eziningana ze-chroming, wawela phansi waphuka; Ezinye izingxenye ezicijile (ukucindezela okukhulu kwangaphakathi) kuzoqhekeka lapho kuthathwa. Lezi zingxenye zihlehliswe kakhulu futhi ziqhekeke ngaphandle kwengcindezi yangaphandle, engasakwazi ukusetshenziselwa ukubuyisela ubulukhuni bokuqala yi-dehydrogenation.
Lapho ukhula khona amandla abonakalayo, ukukhuthaza ukuzwela okukhulu kwe-hydrogen eMbrittlement. Lona umqondo oyisisekelo okufanele acaciswe ngochwepheshe bokwelashwa komhlaba lapho behlanganisa imininingwane yenqubo ye-electroplating yenqubo. Ama-Steel Anamandla Amandla we-Tensile σ we-σ we-105kg / mm2 edingwa amazinga aphesheya kufanele acindezelwe ekucindezelweni kwangaphambi kokuphola kanye nokuphenya kwe-dehydrogenation ukwelashwa okuthe xaxa. Imboni yezezindiza yaseFrance idinga ukwelashwa okuhambisanayo kwe-dehydrogenation ngenxa yezingxenye zensimbi nge-Revel Amandla we-Resse> 90kg / mm2.
Ngenxa yokuxhumana kahle phakathi kwamandla ensimbi nobulukhuni, kubonakala kahle futhi kulula ukwahlulela ukuzwela kokucabanga kwe-hydrogen ukuzwela kobulukhuni kunobulukhuni. Ngoba inqubo ephelele yokudweba nomshini wemishini kufanele imakwe ngobulukhuni bensimbi. E-electtroplating, sathola ukuthi ubunzima bensimbi ezungeze i-HRC38 baqala ukukhombisa ubungozi bokuqhekeka kwe-hydrogen eMbrittlement. Ezingxenyeni eziphakeme kune-HRC43, ama-dehydrogenation kufanele abhekwe ngemuva kokufaka ipuleti. Lapho ubulukhuni bumayelana ne-HRC60, ukwelashwa kwe-dehydrogenation kumele kwenziwe ngokushesha ngemuva kokwelashwa komhlaba, ngaphandle kwalokho izingxenye zensimbi ziyoqhekeka kungakapheli amahora ambalwa.
