Q315NS simbi

Mhedzisiro yewelding thermal process pane electrochemical corrosion yeQ315NS muH2SO4 uye HCl mhinduro yakaongororwa. Akasiyana weld thermal cycles ane tembiricha dzakasiyana dzepamusoro dzakashandiswa muGleeble thermal-force simulation test muchina kutevedzera weld HAZ, uye kuyerwa kwe electrochemical kwakaitwa. Mhedzisiro yacho inoratidza kuti microstructure yegranular bainite yakagadzirwa muCGHAZ nepo mamwe aisanganisira ferrite uye pearlite. Iyo electrochemical corrosion yeHAZ yakasiyana yakanga yakasiyana muH2SO4 uye HCl, nekuda kwe microstructure yakasiyana. Iyo BM neHAZs mu50 wt. % H2SO4 mhinduro ine imwe passivation maitiro, nepo pakanga pasina passivation maitiro mu 3.5 wt. % mushonga weHCl. Kudzivirirwa nekuora muHAZ kwakaderera pane kuri muBM. Mukuwedzera, iyo corrosion resistance muCGHAZ ndiyo isina simba
