Abstract <p>Material surfaces used in technological applications must be functional for desired performance. Nickel deposition is used extensively in industrial sectors due to its high corrosion resistance. This coating is one of the oldest surface protection methods used in the decorative applications of steels. However, wear properties of this coating are poor and this case restricts the use of Ni coating. With the development of engineering sciences in technology, the needs for materials with high corrosion and wear resistance are increasing. The demand for increased performance of industry has forced the use of duplex coated metals and duplex surface treatments applied on metals increasingly become widespread. One of these duplex surface treatments is Ni–B and Ni–Si–B coating systems. In these processes, boriding surface treatments, followed by Ni coating, were performed and multi-layer coatings were obtained. In this study, a duplex structure was obtained by box boronizing process on Ni coated by electrochemical method surfaces on AISI 1040 steel. The analyses of the formed layers were made using X-rays, optical and SEM (Scanning Electron Microscope) microscope. Boride layers were investigated in terms of friction, wear, and microhardness properties. The best wear properties were obtained for the sample borided at 900°C for 6 h. Wear tests showed that boriding at 900°C for 6&#xa0;h and 900°C for 6 h followed by Ni electroplating improved the wear resistance.</p>
