| Abstract: | Microstructure, bond strength and powder size of supersonic ARC sprayed Al coatings were investigated by OM, SEM , Vickers microhardness test, tensile bond strength test and salt spray test. Experiment results showed that aluminum coatings by supersonic ARC spraying have better corrosion resistance, higher microhardness, higher bond strength and smaller powder size as well as lower porosity than that by conventional ARC spraying. |

| Keywords: | ARC spraying coatings bond strength corrosion supersonic ARC spraying |
