Investing Wear Resistance Of EN-45 Steel through Detonation -Sprayed Coatings : A Study Of Timo(CN)and NiCrALY+0.4 wt%CeO2
Main Article Content
Abstract
This research investigates the wear behavior of uncoated EN-45 steel and detonation-sprayed TiMo (CN) and NiCrAlY+0.4 wt%CeO2 coatings on EN-45 substrates. The detonation gun spray process was utilized to successfully deposit the coatings, which were subsequently characterized by SEM, EDAX, and XRD analyses. Wear tests, conducted under normal loads of 40N, 50N, and 60N, revealed that coated materials exhibited significantly lower cumulative volume loss compared to uncoated samples. Among the coatings, NiCrAlY+0.4 wt%CeO2 demonstrated superior wear resistance, lower cumulative volume loss, and higher bonding strength. These findings suggest that detonation-sprayed NiCrAlY+0.4 wt%CeO2 coatings are highly effective in enhancing the wear resistance of EN-45 steel and can be applied in high-wear applications, particularly in the automotive industry for components like axles. Future research could explore the long-term performance and cost-effectiveness of these coatings in real-world applications.
