Abstract: This study presents a comprehensive examination of surface coating strategies to improve the wear resistance of EN45 steel using detonation gun (D-Gun) sprayed TiMo (CN) and NiCrAlY+0.4 wt% CeO₂ coatings. EN45 is commonly deployed in automotive suspension and axle systems but suffers from poor surface durability under frictional stress. Through X-ray diffraction (XRD), scanning electron microscopy (SEM), and Energy Dispersive X-ray Analysis (EDAX), the coatings were characterized for phase composition, morphology, and structural integrity. Pin-on-disc tests were performed under dry sliding conditions with varying loads to assess wear rate and frictional behavior. The results affirm that both coatings significantly enhance performance, with NiCrAlY+CeO₂ exhibiting superior wear resistance. These findings position detonation-sprayed coatings as viable upgrades for extending the service life of EN45-based automotive components.
