Insimbi ye-Q315NS

Umthelela wenqubo yokushisa yokushisela ekugqwaleni kwe-electrochemical ye-Q315NS ku-H2SO4 nesisombululo se-HCl iphenywe. Imijikelezo ehlukene ye-weld eshisayo enamazinga okushisa aphezulu ahlukene asetshenziswa emshinini wokuhlola ukulingisa amandla okushisa we-Gleeble ukuze kulingise i-HAZ yokushisela, futhi kwenziwa ukukalwa kwe-electrochemical. Imiphumela ibonisa ukuthi i-microstructure ye-granular bainite yakhiqizwa e-CGHAZ kuyilapho enye yayihlanganisa i-ferrite ne-pearlite. I-electrochemical corrosion ye-HAZ ehlukene yayihlukile ku-H2SO4 ne-HCl, ngenxa ye-microstructure ehlukene. I-BM kanye ne-HAZs ku-50 wt. % Isixazululo se-H2SO4 sinokuziphatha okuthile kokungenzi lutho, kuyilapho bekungekho ukuziphatha kokungenzi lutho ku-3.5 wt. % Isixazululo se-HCl. Ukumelana nokugqwala kuma-HAZ kungaphansi kwalokho okuku-BM. Ngaphezu kwalokho, ukumelana nokugqwala ku-CGHAZ kubuthakathaka
