Microstructure and Properties of Iron Aluminide Coatings

چکیده
Corrosion-resistant coatings based on the iron aluminide intermetallic compound Fe3Al are currently being investigated for fossil energy applications. Fe3Al possesses excellent intrinsic high-temperature oxidation and sulfidation resistance, and a significant effort has been made in the development of bulk alloys based on it. While substantial progress has been made, the widespread use of these alloys has been hampered by a combination of low room-temperature ductility and high-temperature creep resistance [1]. The use of Fe3Al as a coating material on a less corrosion-resistant substrate with more suitable mechanical properties offers one alternative for overcoming these limitations, with applications in the fossil energy industry.

Aluminide Coatings for Power Generation Applications
In order to form model aluminide coatings for studying critical issues related to their high temperature oxidation and corrosion performance, a laboratory chemical vapor deposition (CVD) procedure is being used to more rigorously control the coating process in terms of composition, purity and microstructure. One ferritic (Fe-9Cr1Mo) and one austenitic alloy (304L) were selected as substrate mat...
متن کاملInterdiffusion Behavior in Aluminide Coatings for Power Generation Applications
One of the critical issues for the application of iron aluminide coatings is the loss of Al from the coating into the Fe-base substrate alloys which do not contain aluminum. The interdiffusion behavior between chemical vapor deposited (CVD) aluminide coatings and ferritic and austenitic substrates is being studied for times up to 10,000h in the temperature range of 500-800oC. Coatings were synt...
متن کاملRhodium and Hafnium Influence on the Microstructure, Phase Composition, and Oxidation Resistance of Aluminide Coatings
A 0.5 μm thick layer of rhodium was deposited on the CMSX 4 superalloy by the electroplating method. The rhodium-coated superalloy was hafnized and aluminized or only aluminized using the Chemical vapour deposition method. A comparison was made of the microstructure, phase composition, and oxidation resistance of three aluminide coatings: nonmodified (a), rhodium-modified (b), and rhodiumand ha...
متن کاملFormation and Evaluation of Oxidation Behavior of Zirconia- Aluminide Coating on Nickel- Based Alloy
Practical applications of thermal barrier coatings with aluminide bond-coats are limited due to oxide scale spallation of the aluminide coating under applied thermal stresses. Considering the positive effects of oxygen-active elements or their oxides on the high temperature oxidation behavior, in this research zirconia was introduced into an aluminide coating. For this purpose, a Watts type bat...
متن کاملHigh-temperature Corrosion Behavior of Iron Aluminide Alloys and Coatings
A multi-year effort has been focused on optimizing the long-term oxidation performance of ingot-processed (IP) and oxide-dispersion strengthened (ODS) Fe3Al and iron aluminidebased coatings. Based on results from several composition iterations, a Hf-doped alloy (Fe28Al-2Cr-0.05at.%Hf) has been developed with significantly better high temperature oxidation resistance than other iron aluminides. ...
