•Our novelty resides in an unified approach to study the sliding wear behavior of the friction stir processed cast NiAl bronze.•The study was carried out by applying full factorial design of experiment approach.•In this study it was observed that a refined grain structure as a result of FSP resulted in enhanced wear resistance as compared to base.
This paper embodies the findings of a study on the effect of normal load, sliding velocity, and surface temperature on the dry sliding wear behavior of friction stir processed C95500 nickel aluminum bronze (NAB) alloy. Adhesive wear behavior was studied using the pin on disk tribometer as per ASTM G99-04 standard, using two level full factorial approachs. The friction processed (FSPed) surface under study showed lower wear rate than as-cast alloy. The wear rate in both conditions, as-cast as well as FSPed, at high temperature was found lower than the one during ambient temperature condition. The wear mode and operating wear mechanism were assessed through SEM study of the worn surface and wear debris.
