Özet
In this study, AISI 1050 steel was boronized at temperatures of 800, 850, 900, 950 and 1000 degrees C for 3, 6, and 9 hours by means of a pack boronizing process. The formation of the boride layer was investigated. The characterization of the boronized surfaces was determined by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Although dual phase, FeB and Fe2B were observed in the boride layer, the intensity of the FeB was slight and collected only near the outer surface which is the desired structural morphology. As the boronizing temperature and holding time strongly affect the results of both boride layer thickness and the surface hardness of the material, multi-objective mathematical models were developed for optimization. Energy consumption during boronizing was also considered. Hence, the optimum values for both temperature and holding time were determined, both of which maximize surface hardness and boride layer thickness while minimizing energy consumption.
