Coatings micro-hardness measurement

Vickers microhardess
The hardness  measurements by microindentation are done according to ASTM E-384, using a  Vickers indenter (a square base diamond pyramid with an apical angle of 136°). The result for Vickers microhardness is reported in kg/cm2 and is proportional to the load (L) divided by the square of the diagonal (d) of the indentation measured from the test. The load on the Vickers microhardness indenter ranges from 5 g to 150 g.
