In this study, the microstructure and microhardness properties of manganese steel coated with chromium carbide (CrC) using Thermo Reactive Diffusion (TRD) method at 900℃ and 1100℃ for 4 hours were investigated. The surface morphology of the coating was characterized by scanning electron microscopy (SEM), elemental distribution, X-ray spectroscopy (EDS). Microhardness properties were determined using the Vickers method. Microstructural properties and microhardness results were characterized. The microstructure results showed that the coating process at 1100℃ was metallurgically more uniform. The minimum coating thickness was 14.95 μm at 900℃ and the maximum thickness was 24.1 μm at 1100℃. In EDS measurements, while CrC was dense in the coating region, Fe density increased towards the substrate. In the microhardness measurements, the highest value was measured as 2371 HV0.5 in the sample coated at 1100℃. Based on these results, it is thought that CrC coating forms a better coating layer especially at high temperatures.
