Simba rakakwirira rekuzvimirira rinoburitsa kupwanya kana galvanized. Unoda kutarisirwa kwakakosha.
Hydrogen embbrittlement inowanzoonekwa nekunonoka kupwanya pasi pekushushikana. Pave paine miti yemotokari, washers, screws, pepa rematsime uye mamwe mitezo yegungwa, mumaawa mashoma mushure mekunge gungano ratyoka, iro rakakamurwa chikamu che40% ~ 50%. Mukuita kwekushandisa zvikamu zveCadmium-zvakavezwa zvechigadzirwa chakakosha, pakanga paine Batch Crack kupwanya, uye dambudziko renyika rakakosha rakagadziriswa uye maitiro akasvibiswa akasimba akagadzirwa. Mukuwedzera, pane mamwe marudzi eHydrogen hairatidzi kunonoka kupokana phenomenon, akadai (expectating yeHanger kuitika brittle bracture phenomenon; Iyo mandrel yeimwe pfuti, mushure menguva yakati wandei, yakawira pasi uye ikaputsa; Zvimwe zvikamu zvakadzimwa (kushushikana kwemukati kwemukati) kuchapenga kana kurwa. Izvi zvikamu zvine hydrogenated uye kupaza pasina kushushikana kwekunze, izvo hazvigone kushandiswa kudzoreredza kuoma kwekunetseka nekushatirwa.
Iyo yepamusoro Simba rezvinhu, iyo yakakura iyo hydrogen embbrittlement kungwara. Iyi ipfungwa yekutanga iyo inofanirwa kujekeswa neyekumusoro mapepa ekurapa maitiro kana uchinyora magetsi ekugadzirisa maitiro. Steels neTensile Simba σb> 105KG / MM2 inodikanwa neInternational Stitule inofanirwa kuiswa pasi pekutanga kushushikana uye kutumira-kuisa kushatisa kushomeka kurapwa. Iyo French Aviation indasitiri inoda kuenderana kushomeka kweshiri kurapa kwesimbi zvikamu neyebereko ine simba σs> 90kg / mm2.
Nekuda kwekunyorerana kwakanaka pakati peSimbi Simba uye kuomarara, inonyanya kuomarara uye yakakodzera kutonga iyo hydrogen embbrittlement yekunzwa kwezvinhu nekuomesesa pane nesimba. Nekuti yakakwana yechigadzirwa yekudhirowa uye machining maitiro inofanira kuve yakanyorwa nesimbi yakaoma. MuElectroplating, takawana kuti kuomarara kwesimbi kutenderedza HRC38 vakatanga kuratidza njodzi yehydrogen embbrittlement. Zvikamu zvakakwirira kupfuura hrc43, kushomeka kunofanirwa kutariswa mushure mekutarisa. Kana kuomarara kwacho kweHRC60, kushomeka kweshiri kunofanirwa kuitwa nekukurumidza mushure mekurapwa kwemukati, zvikasadaro zvidimbu zvesimbi zvichapera mukati memaawa mashoma.
