Abstract
A preparation method for an iron-based alloy powder EBSD test sample includes the following steps: surface electrolytic activation of an iron-based powder; ultrasonically cleaning the powder, and drying the powder to obtain a surface activated powder; adding the surface activated powder to a chemical embedding solution for ultrasonic dispersion; after the ultrasonic dispersion, performing a plating process; then heating to 80-92° C. for chemical reaction to prepare an iron-based alloy bulk which coated with nickel. The plating process is as follows: still standing, stirring, and repeating the still standing is taken as a cycle, and at least one cycle is performed to complete the plating process. Then grinding and electropolishing are done to the obtained iron-based alloy bulk coated with nickel to obtain the iron-based alloy powder EBSD test sample.
