| In this study, the specimens made by tightening stainless steel high-strength bolt 10TSUS on carbon steel SM490Y plate were used. Also, epoxy resin plate and alumina spraying were adopted as the insulation method to prevent the corrosion of dissimilar metal contact, which is a concern at the contact part of different materials. Then, a combined cycle test was conducted using eight types of specimen conditions under which these conditions were changed, and the corrosion properties were investigated in detail.As a result, it was clarified that no clear phenomenon of the corrosion depth of the base carbon steel plate near the washer and the insulating material was observed in any of the insulation methods. |
