With the help of metallographic polishing machines and argon ion polishing equipment, non-destructive real section polishing can be performed on powders, films, blocks, foreign objects, pits/protrusions

Example:

Preparation of foreign object cross-section samples

The cross-sectional area of positive electrode material powder (nanomaterials have also entered the era of "substructure" in industrial applications, such as the internal pores, internal growth orientation, core shell multilayer structure of powder particles, etc.).

Cross section of lithium-ion battery separator (polymer film has strong ductility, and it is difficult to obtain the true morphology of the fracture surface of a smooth and non-destructive sample using conventional methods. Europol has mastered this sample preparation process)

Application of multi-layer film thickness testing (precise cross-section sampling)
