Abstract

The paper studies the improvement of cavitation erosion resistance for Nimonic 80A alloy whose surface has been subjected to nitriding. The cavitation erosion tests were performed with an ultrasonic vibrating device in accordance to ASTM G32-2010. The cavitated samples were further investigated by optical and scanning electron microscopy. The analysis of the cavitation curves showed 8.65 times decrease in mass loss and 8 times increase in cavitation erosion resistance of nitrided samples compared to those in solution treatment state.

Keywords: Nimonic 80A alloy, nitriding, cavitation erosion
