Metrology of indentations
For hardness measurements, the indentation of diamond tips into a material's surface is often used. A diamond tip is driven into the material with a defined load. The force response of the material is recorded, providing information on the hardness properties of the material.
The image shows a 3D measurement of an indentation. The AFM provides accurate measurements that allow quantification of the indentation volume.
The measurement was performed in "Static Force" operating mode.
