Outline of Research at the Start

This study aims to suppress ZrCr2 formation at the Cr/Zr interface in Cr-coated Zr alloys by doping specific elements. We will screen effective dopants, optimize their content, and reveal mechanisms to enhance interface stability without losing oxidation resistance.
