Wear Behavior of Friction Stir Processed NAB Alloys in Marine Environment

Nickel Aluminum Bronze (NAB) alloy specimens subjected to Friction Stir Processing (FSP) with and without particulate addition were subjected to tribological testing in a reciprocating sliding tester which can perform sliding test on specimens immersed in sea-water. Stainless steel ball was slid aga...
