Abstract Scope |
A large-volume 3D EBSD system consisting of an SEM (Zeiss crossbeam XB 1540) with a dedicated sample docking station, an adapted mechanical polishing automaton (ATM X-Change), and a collaborative robotic arm (Universal Robots UR5) has been assembled. An in-house designed software orchestrates the whole automation process via a communication hub. To obtain accurate serial sections of constant thickness, the polishing parameters (e.g., force exerted on the polishing cloths) were fine-tuned in a large number of preliminary tests on the material of interest. All samples were featured with top-observable side markers for polishing depth measurement. These markers were produced by plasma focused ion beam (PFIB). 3D EBSD data sets with a total volume of 300 × 300 × 300 µm³ reconstructed from approx. 100 slices were acquired to study the grain boundary corrosion behavior of 316L stainless steel. Corrosion tests were applied on the remaining bulk surface. |
