Materials Properties



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
