Q315NS ígwè

Achọpụtara mmetụta nke usoro ikpo ọkụ ọkụ na electrochemical corrosion nke Q315NS na H2SO4 na HCl ngwọta. A na-eji okirikiri ọkụ weld dị iche iche nwere oke okpomọkụ dị iche iche n'ime igwe nnwale simulation nke Gleeble iji mee ka weld HAZ, wee tụọ nha electrochemical. Nsonaazụ gosiri na e mepụtara microstructure nke granular bainite na CGHAZ ebe ndị ọzọ nwere ferrite na pearlite. Igwe ọkụ electrochemical nke HAZ dị iche iche dị iche na H2SO4 na HCl, n'ihi microstructure dị iche iche. BM na HAZ na 50 wt. % H2SO4 ngwọta nwere ụfọdụ passivation omume, ebe ọ dịghị passivation omume na 3.5 wt. % HCl ngwọta. Nguzogide corrosion na HAZ dị ala karịa nke BM. Tụkwasị na nke ahụ, nkwụsị nke corrosion na CGHAZ bụ nke kachasị ike
