Effect of temperature variation on the corrosion behaviour and semiconducting properties of the passive film formed on chromium oxide coatings exposed to saline solution

•RF sputtered chromium oxide coatings were tested in saline solution at a temperature range 25 to 65° C.•The prepared coatings were confirmed to be mainly chromium (III) oxide.•The passive oxide layers on the coatings possess p-type semiconductor property.•The acceptor defect densities and corrosion...
