Intsimbi ye-Q315NS

Umphumo wenkqubo ye-welding ye-thermal kwi-corrosion ye-electrochemical ye-Q315NS kwi-H2SO4 kunye nesisombululo se-HCl yaphandwa. Imijikelezo ye-weld ye-thermal eyahlukeneyo kunye namaqondo okushisa ahlukeneyo asetyenziswe kumatshini wokuvavanya ukulinganisa amandla okulinganisa amandla e-Gleeble ukulinganisa i-weld HAZ, kwaye imilinganiselo ye-electrochemical yenziwa. Iziphumo zibonisa ukuba i-microstructure yegranular bainite yenziwe kwi-CGHAZ ngelixa ezinye zibandakanya i-ferrite kunye ne-pearlite. I-electrochemical corrosion ye-HAZ eyahlukileyo yayihluke kwi-H2SO4 kunye ne-HCl, ngenxa ye-microstructure eyahlukeneyo. I-BM kunye nee-HAZs kwi-50 wt. Isisombululo se-% H2SO4 sinendlela yokuziphatha ethile, ngelixa bekungekho ukuziphatha kwe-passivation kwi-3.5 wt. % isisombululo seHCl. Uchaso lokutya kwi-HAZs lungaphantsi kunolo lwe-BM. Ukongeza, ukuxhathisa kwe-corrosion kwi-CGHAZ yeyona nto ibuthathaka
