Objectives: Present manuscript deals with the study of wear performance of nickel superalloys namely Superni-76 and Superni750-X, by means of two bodies dry sliding wear method. Methods/Statistical Analysis: The wear performance of the superalloys was noted in as received conditions and after oxidizing the sample at 900°C for 50 hours. Hardened steel balls were used as abrasive body to evaluate the wear volume in each as received and oxidized samples. Findings: The wear volume was calculated with respect to time and sliding distance and graphs were plotted for both the superalloys. The weight change and types of oxides formed after oxidation were identified by XRD and EDX/EDS analysis. The wear surface was also characterised by using FE-SEM/EDS analysis to ascertain the mechanism of wear in the samples. From various characterisation results and observations of volume loss, the effect of oxidation was analysed for these superalloys. Oxidation affects the wear behaviour of nickel based superalloys. The wear mechanism changes due to increase in hardness and brittleness after high temperature exposure. Application/Improvements: It has been found that the oxidation phenomenon leads to the formation of very fine oxide scale on the superalloys. This oxide layer especially in case of Hastelloy-X (Superni-76) was responsible for the improvement in the wear resistance despite of some initial fast volume loss.
