Experiment Brief: Damage-free preparation of a porous Zn alloy with a Cu coating

Damage-free preparation of a porous Zn alloy with a Cu coating
Figure 1. (a) An SEM secondary electron image of the sample in a horizontal position. The two-layer Cu coating is on the left (b) SE image with the sample in a tilted position. The analysis surface is flat and produces good quality EBSD patterns. Some side-milling can be recognized in the pores. (c) An EBSD Image Quality (IQ) map of the ZnAl matrix. (d) An EBSD IPF map on a PRIAS™ bottom image of the ZnAl matrix. (e) A phase map on an IQ map and (f) an IQ map of the Cu coating. The two layers in the Cu coating can be recognized by the grain size. (g) An IPF on a PRIAS center map. (h) EBSD patterns of the ZnAl matrix and Cu coating.

 

The combined experiment brief from EDAX and Gatan demonstrates how materials with a protective or high-strength surface coating can be successfully prepared for EBSD analysis by applying broad beam ion milling.
