The purpose is to measure hardness of samples or films. This is done by pressing an indenter (a small pyramid-shaped diamond tip) into a sample using a known indentation force. This leaves an indent in the sample. The hardness of the sample can then be derived from the dimensions of the indentation (the softer the material the larger the indentation). The samples should have a reasonably low roughness. Otherwise it can be quite difficult to determine the hardness reliably. Also, the samples must be planar and without large protruding features.

Hardness tester

Hardness tester. Positioned in cleanroom F-2

The purpose is to measure hardness of samples or films. This is done by pressing an indenter (a small pyramid-shaped diamond tip) into a sample using a known indentation force. This leaves an indent in the sample. The hardness of the sample can then be derived from the dimensions of the indentation (the softer the material the larger the indentation). The samples should have a reasonably low roughness. Otherwise it can be quite difficult to determine the hardness reliably. Also, the samples must be planar and without large protruding features.

Quality Control (QC) for the hardness tester

There is no scheduled calibration of this machine. We do however have three calibration samples which can be used to verify proper operation of the machine. The calibration samples are also good for practicing the measurement procedure. Calibration samples are available in the following three hardnesses: 277 HV, 464 HV and 704 HV. They have been calibrated externally at 1 kgf indentation force and 10 sec indentation time.
