Mechanical features optimization for α-Cr2O3α-Cr2O3 oxide films growing on alloy NiCr30NiCr30

Mechanical features have been investigated in the case of α-Cr2O3α-Cr2O3 thermal oxide films growing on NiCr30NiCr30 alloy in the temperature range 700–900 °C. From previous experimental results obtained by Raman spectroscopy and giving the growth stress evolution in α-Cr2O3α-Cr2O3 films, and based on a modelling of the system, both asymptotic forms and an optimization procedure have been developed which give values for the mechanical characteristic parameters of the system and also its evolution with the oxidation temperature.
