    The aim of this paper is to improve the oxidation resistance of Inconel 600 alloy by diffusion coating. In this study, (Si and Al) and (Al, Si and Y2 O3 ) were simultaneously deposited by cementation process into Inconel 600 alloy at 1120°C for the different times (2,4,6,8)hours. The pack powder mixture consists of 18Al-8Si-2NH4 Cl-72Al2 O3 (wt.%) for silicon modified aluminide diffusion coating and replaced 1% from Al2 O3 by Y2 O3 for yttria doped silicon modified aluminide diffusion coating. Cyclic oxidation was carried out at 50 hours at 900°C, 5 hours for each cycle. The results showed that the coatings microstructure consists of two layers: outer layer and inter-diffusion zone. The best oxidation resistance was found for the deposition by yttria-doped silicon modified aluminide diffusion coating from 6-8 hours of coating time. The phases formed after cyclic oxidation for ..
