Abstract

A method of measuring the Vickers, Knoop or Rockwell hardness of thin films deposited on substrates, wherein a thin film of the desired thickness is deposited on substrates of known hardness and preferably indicated, the actual measurement of hardness is then performed using a body which makes an indentation into the surface, and the known hardness of the substrates is then compared with the composite hardness measured.
