We investigated the hydrogen shielding effect when Zn plating was applied to high-strength steel with a Ti film. High-strength steel has the issue of delayed fracture. Zn plating is widely used, but delayed fracture can occur when hydrogen penetrates into the steel due to sacrificial corrosion protection. On the other hand, Ti is a material with excellent corrosion resistance as a single substance and has a hydrogen absorption effect. Therefore, it is thought that delayed fracture can be prevented by inserting a Ti film and absorbing the hydrogen generated by the sacrificial corrosion protection action of Zn.
