How to etch
✅ Ensure your initial sample is polished to a smooth surface without deformations or scratches.
✅ Select the correct etching fluid for the material
✅In certain cases it is possible to enhance the contrast with light microscope filters in addition to the chemical etching process. This is referred to as "optical etching."
✅In the case of electrolytic etching, a suitable electrolyte, voltage, and sample exposure time should be selected.
