Multi-Scale Correlative Study of Corrosion Evolution in a Magnesium Alloy
16 Aug 2016This application note describes the results of a multi-scale correlative tomography study on the corrosion of a Magnesium alloy. Zeiss’ Atlas 5 is used to efficiently link and navigate between in situ sub-micron X-ray microscopy, nanoscale X-ray microscopy and FIB-SEM tomography. The study provides a description of the complex crack and corrosion byproduct geometries which can lead to a more complete understanding of the underlying mechanisms for corrosion.

ZEISS Atlas 5
ZEISS Research Microscopy SolutionsLarge area imaging for SEM, FE-SEM & FIB-SEM ATLAS combines a 16 bit scan generator and dual super-sampling signal acquisition hardware with image processing and control software for your ZEISS electron microscope. Acquire images up to 32 k x 32 k pixels, with dwell times from 100 ns to > 100 s, adjustable in 100 ns increments. Save your images with eight or sixteen bits of intensity. With the ATLAS “Mosaic Tool” you create large image montages, automatically moving from image tile to tile, and mosaic site to site, resulting in an “Extreme Field of View” image, at SEM nanometer scale resolution. ATLAS provides • reduced number of tiles to acquire, reducing stage motion delay and areal fraction of each image “lost” to overlap • reduced number of overlap “seams”, leading to less beam damage and degradation of the sample • reduced computational complexity
