Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
Cabibbo, M.; Clemente, N.; El Mehtedi, M.; Hamouda, A.H.; Musharavati, F.; Santecchia, E.; Spigarelli, S.... more authors ... less authors ( Elsevier B.V. , 2015 , Article)In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ... -
