Abstract Share this page

In this work, TiAlN and AlCrN coatings were deposited on low-carbon steel ASTM-SA210 Grade A-1 (GrA1) 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), field emission scanning electron microscope (FESEM with EDAX attachment), AFM analysis and XRD 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 TiAlN-coating exhibited better corrosion resistance when compared to AlCrN-coating.
