| Summary: | Abstract This research endeavor was therefore aimed at depositing SiC coatings on AISI 410 stainless steel substrates using plasma spray technique and by so doing determines the wear properties of the resultant composites. Two compositions specimens were prepared by varying the spray parameters as SN7 that contained 70 wt. % SiC and 30 wt. % NiAl and SN8 having 80 wt. % SiC and 20 wt. % NiAl. The morphology, composition, and wear properties of the coatings were characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques. The samples were tested to evaluate their wear characteristics in dry sliding condition, and the wear rates are determined. The findings observed from the study show that the two coatings SN7 and SN8 offered greater wear protection than the base metal of steel. SN8 performed better as suggested by the SEM analysis revealing dense coating structure and greater hardness in the coating. The established wear mechanisms were categorized under abrasive wear and adhesive wear. The findings of this research also demonstrate that while the AISI 410 steel substrate is suitable for wear-related applications, plasma-sprayed SiC coating significantly improves the wear resistance of the steel. |
