In this study, niobium boride layers were deposited on the surface of AISI 1010 steel by a duplex surface treatment. In the first step of duplex treatment, boronizing treatment was performed at 900°C for 2 h and then pre-boronized steels were niobized at 850, 900, 950°C for 1, 2, 3 and 4 h using thermo-reactive deposition/diffusion (TRD) method. Presence of the niobium boride phases were confirmed by Xray diffraction (XRD), scanning electron microscope (SEM) and microhardness methods. The hardness of coating layer was 2598±482. Experimental results show that the depth of the coating layers changes between 1.5 μm to 7.19 μm. The higher temperature the higher thickness of coating layer was obtained.
