Abstract Scope High temperature oxidation behavior of Inconel 625 produced by Selective laser melting in longitude and transverse directions was studied and compared with that of the wrought alloy. Oxidation tests were performed on alloys at 850 and 1000 C in laboratory air in order to evaluate their oxidation resistance. X ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy were used to characterize the oxidation behavior. The experimental results revealed that oxide scales of all superalloys were similar in nature and morphology with small differences due to additive manufacturing. A slow growing, continuous and well adherent chromia oxide scale on the all alloys surface formed which protected the alloy against rapid oxidation attack. the growth of the chromia base oxide scale resulted in oxidation- induced depletion in the subsurface zone of the alloy.
