Friction stir surface alloying process parameters such as tool rotation speed, traverse speed and tool tilt angle are optimized for successful incorporation of Molybdenum particles possessing higher hardness, wear resistance and corrosion resistance into Al 1050 alloy matrix. The optical microscopy analysis showed uniform distribution of Molybdenum particles in grain refined Al 1050 base alloy. Addition of Molybdenum induced Al5Mo intermetallic generation in the processed system. Scanning Electron Microscopy and Energy Dispersive X-Ray Spectroscopy are used to understand the elemental analysis, percentage of incorporation and distribution of Molybdenum in the processed system. Molybdenum distribution in the Aluminium matrix, presence of Al5Mo intermetallic phase and grain refining during friction stir surface alloying process lead to improved surface properties in Aluminium- Molybdenum system. Vickers hardness in the top and cross section surfaces of friction stir surface alloyed samples improved significantly compared to the unprocessed system.
