Original optical data from the article "In situ high-resolution optical microscopy survey of the initial reactivity of multiphase ZnAlMgSi coating on steel"

Article title: In situ high-resolution optical microscopy survey of the initial reactivity of multiphase ZnAlMgSi coating on steelAuthors: Guilherme Adinolfi Colpaert Sartori, Oumayma Gabsi, Tiago Machado Amorim, Viacheslav Shkirskiy, Polina VolovitchPublished in: Metals (MDPI), 2025 Refer to the original article for a detailed description of the optical image dataset. The only difference relative to the published figures is that the image resolution has been halved—from 2000 × 2000 to 1000 × 1000 pixels—to meet the size constraints of the Zenodo repository. These reduced-resolution images remain sufficient to support the same conclusions as in the article.
