Abstract
The objective of this study is to evaluate the diffusion behavior of Al and Si from a coatings in the microstucture of Fe-Si steel. Steel samples deposited with Al-Si alloy are prepared by ion plating process, followed by annealing treatments for diffusion at $1050^{\circ}C$. Several intermetallic phases are found in the coatings and they are identified as Fe-Al and an orderd Fe-Si compounds. Series of different concentration profiles through the sample have been obtained and Si content reaches about 5 wt% in case of 90 minutes of diffusion time.
