Effect of Surface Roughness on the Oxidation Behavior of the Ni-Base Superalloy ME3
Source abstract
Abstract
Ni-base superalloys are used in applications, such as jet aircraft engines and power production facilities that require excellent elevated temperature oxidation resistance. This present work evaluated the effect of surface roughness on the oxidation behavior of the Ni-base superalloy ME3. Isothermal oxidation tests were performed in air at different times to investigate the oxide growth kinetics. The surface oxides were also characterized using scanning electron microscopy and x-ray diffraction. The surface roughness was measured using a linear scanning profilometer. The surface roughness measurements were correlated to the oxidation rates and an empirical model is proposed to describe the effect of surface roughness on the oxidation behavior.
