This is dependent on hardness test method used and the hardness
of the coating.
Rockwell superficial HR-15-N may only be suitable for hard coatings
in excess of 83 HR-15-N at 300 microns thick.
For Vickers hardness the general recommended minimum thickness of
coating should be at least 1.5 times the diagonal of the
indentation.
