Investigation of Nimonic Alloy: Plasma Interaction in Different Plasma Pulses Using a Small Plasma Focus Device

摘要

The results of NiAlN-ions implantation onto the Nimonic 75 samples by a 4 kJ plasma focus device in order to improve the hot corrosion resistance of the specimens are investigated. XRD results reveal the formation of a nano-crystalline nickel nitride and aluminum nitride coating on the surface of the samples. FESEMs indicate changes in surface morphology before and after ion implantation. The electrochemical impedance spectroscopy and hot corrosion results show that the corrosion resistances are significantly improved when NiAlN films are deposited into the Nimonic 75 samples.
