Abstract
Kebutuhan teknologi akan material dengan karakteristik mampu beroperasi pada temperatur tinggi semakin tinggi. Proses oksidasi memungkinkan terjadi pada pengoperasian temperatur tinggi yang dapat mempengaruhi performa material. Inconel 625 merupakan paduan super berbasis nikel yang mampu beroperasi pada temperatur tinggi. Penelitian ini bertujuan untuk menganalisis pengaruh variasi temperatur dan waktu oksidasi terhadap evolusi fase oksida pada Inconel 625. Metode penelitian ini dengan melakukan oksidasi temperatur tinggi Inconel 625 pada temperatur 600℃, 700℃ dan 800℃ dengan waktu oksidasi 2, 5, 10, 17 dan 24 jam. Pengujian yang digunakan pada penelitian ini yaitu X-Ray Fluoresence (XRF), Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), X-Ray Diffractometry (XRD), dan Metalografi. Dalam penelitian ini diketahui peningkatan temperatur dan lamanya waktu oksidasi meningkatkan pembentukan dan penambahan fase pada Inconel 625. Fase yang terbentuk selama oksidasi adalah matriks γ, M23C6 dan η. Sedangkan lapisan oksida yang terbentuk adalah NiCr2O4.
==========================================================
The technological need for materials with characteristics
capable of operating at high temperatures is getting higher and higher. The oxidation process may occur at high operating temperatures which can affect the performance of the material. Inconel 625 is a nickel-based superalloy that is capable of operating at high temperatures. This study aims to analyze the effect of variations in temperature and oxidation time on the evolution of the oxide phase in Inconel 625. The method of this research is to carry out high-temperature oxidation of Inconel 625 at temperatures of 600℃, 700℃ and 800 with oxidation times of 2, 5, 10, 17 and 24 hours. The tests used in this study were X-Ray Fluorescence (XRF), Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), X-Ray Diffractometry (XRD), and Metallography. In this study, it was found that increasing the temperature and the length of time for oxidation increased the formation and addition of phases to Inconel 625. The phases formed during oxidation were γ matriks, M23C6 and η. While the oxide layer formed is NiCr2O4.
