Q315NS kila

Ua noiʻi ʻia ka hopena o ke kaʻina hana wela ma ka electrochemical corrosion o Q315NS ma H2SO4 a me HCl solution. Ua hoʻohana ʻia nā pōʻai wela weld like ʻole me nā wela kiʻekiʻe o ka Gleeble thermal-force simulation testing machine e hoʻohālike i ka weld HAZ, a ua lawe ʻia nā ana electrochemical. Hōʻike nā hopena i kahi microstructure o granular bainite i hana ʻia ma CGHAZ aʻo nā mea ʻē aʻe he ferrite a me ka pearlite. ʻOkoʻa ka ʻino electrochemical o HAZ like ʻole ma H2SO4 a me HCl, ma muli o nā microstructure ʻokoʻa. ʻO nā BM a me nā HAZ i 50 wt. Loaʻa i ka % H2SO4 kekahi ʻano hana passivation, ʻoiai ʻaʻohe ʻano passivation ma 3.5 wt. % HCl solution. ʻOi aku ka haʻahaʻa o ka pale ʻana i ka corrosion ma HAZ ma mua o ka BM. Eia kekahi, ʻo ke kūpaʻa corrosion i ka CGHAZ ka nāwaliwali loa
