AbstractIn this research using submerged friction stir processing SFSP method to produceAl6061 Al2O3 surface nanocomposite and its characterization was investigated Forthis purpose after optimizing FSP machine special tool and SFSP parameters by usingartificial neural networks ANN model SFSP was applied underwater as the coolingmedia on an extruded nanocomposite strip that had been embedded into a grove onAl6061 T6 sample Measurement of temperature showed that using cooling media candecrease temperature of process up to 100 C and it can produce a sound stir zone Microstructure of the stir zone thermo mechanical affected zone and base metal wasstudied using optical microscopy and Scanning electron microscopy Investigation ofmechanical properties consisted of average hardness of stir zone Wear behavior ofsamples was investigated using wear sliding machine at ambient temperature and400 C Results indicated that using reinforcement Al2O3 nano particles can notimprove wear behavior of specimens at room temperature On the other hand wear testat 400 C on nanocomposite specimen showed higher wear properties in comparisonwith base metal and SFSP samples In this test depth of wear path in nanocomposite SFSP and base metal specimens were 0 36mm 1 97mm and 1 63mm respectively
