Surface Profiling

Surface roughness measurement to 20 nanometre resolution using Vertical Scanning Interferometer..

Sub nanometre resolution using phase scanning interferometry..

Stylus profilometery.
 

Hardness testing

The image on the right shows a hardness test indent apparently measuring 1.28mm diagonally (d).

As it is magnified 5x, this equates to 0.256 mm

The force used was 10 Kilograms.

Therefore, from the equation 1.854 x (Force/d²)

Vickers hardness = 282.9

 

 

Tensile Testing

Testing of materials in tension or compression. 5 N or1 KN load cells on H1KS , 25 KN load cell on 25ST
