A study to investigate the Young modulus dependence of nanoscopic friction coefficient in hard coatings is presented. For the CrN films, it is shown that the changes in the friction coefficient can be traced back to variations of the Young modulus. It was found that CrN films, diamond and diamond-like carbon (DLC) films show the same linear dependence between friction coefficient and the inverse of the Young modulus.
