Abstract
Core-shell microparticles, along with methods of their fabrication and use, are provided. The core-shell microparticles may include a core comprising a first metallic material having a first chromium content and a shell surrounding the core and comprising a second metallic material having a second chromium content that is less than the first chromium content. For example, the first chromium content may be 5% by weight or greater of elemental chromium within the first metallic material.
