Tsanangudzo yedetail
High simba fasteners anoburitsa crispness kana galvanized.Unoda kunyatsotarisirwa.
Hydrogen embrittlement inowanzoonekwa nekunonoka kuputsika pasi pekunetseka.Pave paine zvitubu zvemotokari, washers, screws, mashizha zvitubu uye zvimwe zvikamu zvakabatiswa, mumaawa mashoma mushure memusangano waputswa, chikamu chekutyoka che40% ~ 50%.Mukuita kushandisa macadmium-plated zvikamu zvechigadzirwa chakakosha, pakanga paine batch crack fracture, uye dambudziko rekiyi renyika rakagadziriswa uye maitiro ekuita dehydrogenation akagadzirwa.Pamusoro pezvo, pane mamwe hydrogen embrittlement isingaratidzi kunonoka kutsemuka chiitiko, senge: electroplating hanger (simbi waya, waya yemhangura) nekuda kwenguva zhinji dze electroplating uye pickling plating, hydrogen kupinda kwakanyanya, kazhinji kuoneka mukushandisa peta. kuitika brittle fracture phenomenon;Mandrel yepfuti, mushure menguva dzinoverengeka dzechroming, yakawira pasi ndokutyoka;Zvimwe zvikamu zvakadzimwa (zvakakura zvemukati kushushikana) zvichatsemuka kana pickling.Zvikamu izvi zvakanyanya hydrogenated uye zvinotsemuka pasina kushushikana kwekunze, izvo zvisingakwanisi kushandiswa kudzorera kuoma kwepakutanga ne dehydrogenation.
Iyo yakakwirira simba rezvinhu, iyo yakakura iyo hydrogen embrittlement kunzwa.Iyi ipfungwa yakakosha inofanirwa kujekeswa nehunyanzvi hwekurapa kwepamusoro pakugadzira magadzirirwo emagetsi emagetsi.Simbi dzine simba rekusimba σb> 105kg/mm2 dzinodiwa nemitemo yenyika dzinofanirwa kuve pasi pekunetseka kwekutanga-kupisa uye kurapwa kwepashure kwedehydrogenation zvinoenderana.Indasitiri yekuFrance yendege inoda inoenderana dehydrogenation kurapwa kwezvikamu zvesimbi zvine simba regoho σs> 90kg/mm2.
Nekuda kwekunyorerana kwakanaka pakati pesimba resimbi uye kuoma, zviri nyore uye zviri nyore kutonga hydrogen embrittlement senitivity yezvinhu nekuoma kupfuura nesimba.Nekuti chakakwana chigadzirwa kudhirowa uye machining maitiro anofanirwa kucherechedzwa nekuoma kwesimbi.Mune electroplating, takaona kuti kuoma kwesimbi kwakatenderedza HRC38 kwakatanga kuratidza njodzi yekutyoka kwehydrogen embrittlement.Kune zvikamu zvakakwirira kupfuura HRC43, dehydrogenation inofanirwa kutariswa mushure mekuputirwa.Kana kuoma kuri kuita HRC60, kurapwa kwe dehydrogenation kunofanirwa kuitwa nekukurumidza mushure mekurapwa kwepamusoro, zvikasadaro zvikamu zvesimbi zvinotsemuka mukati memaawa mashoma.
