Aluminum base coatings have been used many years as a protective layer on steels, but application of this coating is limited due to its poor wear and corrosion resistance. The main goal of this work is increasing corrosion and consequently erosion-corrosion resistance of these coatings. Steel samples were coated with different aluminum alloy by means of ion beam sputtering and then implanted by different dose and energy nitrogen ion beam. We studied properties of this coating before and after ion implantation by potentiodynamic polarization, pin on disk and rotating coupon tests. Optical and electron microscopes were also used. The results of these tests are discussed in the paper.
