High Temperature Oxidation Performance of Aluminide Coatings
In order to determine the potential benefits and limitations of aluminide coatings, coatings made by chemical vapor deposition (CVD) on Feand Ni-base alloy substrates are being evaluated in various hightemperature environments. Testing of coatings on representative ferritic (Fe-9Cr-1Mo) and austenitic (type 304L stainless steel) alloys has found that high frequency thermal cycling (1h cycle tim...
متن کاملMicrostructure and Properties of Iron Aluminide Coatings
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...
متن کاملAluminide 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 کاملDevelopment of Oxidation Protection Coatings for Gamma Titanium Aluminide Alloys
Metallic material systems play a key role in meeting the stringent weight and durability requirements for reusable launch vehicle (RLV) airframe hot structures. Gamma titanium aluminides (γTiAl) have been identified as high-payoff materials for high-temperature applications. The low density and good elevated temperature mechanical properties of γ-TiAl alloys make them attractive candidates for ...
