Hot-dip galvanizing steel sheet has been used as building materials or various types of steel sheets for automobiles due to its high corrosion resistance by forming oxide composites layers. It has been difficult to detect metal corrosion products on painted galvanized steel sheet surface qualitatively and quantitatively by using existing inspection methods. In this study, the corrosion products of Zinc and Aluminum on hot-dip galvanizing steel sheet was assigned by comparing the results of terahertz spe...

Qualitative and quantitative non-destructive diagnosis application on hot-dip galvanizing steel sheet by using terahertz spectroscopy

The core shroud specimens (316L stainless steel) were used to characterize the surface hardening layer introduced by machining and to evaluate the SCC susceptibility in the simulated BWR coolant environment. Based on the results obtained, the effect of the surface hardening layer on the SCC susceptibility and its mechanism are discussed. It is suggested that the wall part has clearly higher SCC susceptibility than the support ring part when compared between the as-received materials (with surface hardening ...
