ABSTRACT
Nitrided coatings have been used to increase hardness and to improve the wear and corrosion resistance of structural materials. In this work, TiAlN and AlCrN coatings were deposited on Superfer 800H (INCOLOY 800 H) substrate by using Balzer’s rapid coating system (RCS) machine (make Oerlikon Balzers, Swiss) under a reactive nitrogen atmosphere. The coated samples were subjected to optical microscopy (OM), XRD analysis, Field emission scanning electron microscope (FESEM with EDAX attachment), AFM analysis. The corrosion resistance of the substrate, TiAlN-coated and AlCrN-coated samples in a 3 wt% NaCl solution was evaluated and compared by electrochemical potentiodynamic polarization method. It was found that the AlCrN-coating exhibited better corrosion resistance.
