Advanced Engineering Materials, Volume 25, Issue 8, April 2023., 2023 A combined grinding–burnishing surface modification process is applied to the laser‐clad Stellite 21 alloys. Ball burnishing (BB) improves surface topography by lowering surface roughness and porosity. Increased hardness induced by BB is responsible for higher wear and impact resistance. Higher BB force augments surface integrity improvement.
