High silicon aluminum alloy coatings (HSAACs) are characterized by high surface hardness and excellent wear resistance, and the fineness has a significant impact on their properties. In this study, Al–40Si–5Fe coating was prepared by supersonic plasma spraying using Al–35Si–4Fe powder as raw materia...
