Effect of Al₂O₃ Addition on the Surface Roughness, Adhesion Strength, and Microstructure of Flame-Sprayed Cu–Al–Ni–Fe Alloy Coatings
This study aims to synthesize (Cu-Al-Ni-Fe) alloy composite coatings reinforced with alumina (Al2O3) particles at weight fractions of 0 wt%, 3 wt %, and 6 wt%, deposited on AISI 304L stainless steel substrates using the flame thermal spraying technique. The coatings were evaluated by measuring surface roughness and adh...
