Oxide Dispersion Strengthened Iron Aluminide by CVD Coated Powders

Abstract

This report was prepared by the Powdermet Inc, Euclid, Ohio for the DOE I&I proposal Category 2 entitled "Oxide Dispersion Strengthened Iron Aluminide by CVD coated Powders" Award Number DE-FG36-03GO13012. Fabrication and Evaluation of the Mechanical and Physical Properties of Iron Aluminide composites and its thermal sprayed coatings using chemical vapor deposition (CVD) aluminum, iron and aluminum oxide coated iron powders and iron, aluminum coated aluminum oxide powders were evaluated as part of a DOE I & I Category 2 Program following the successful completion of a preceding SBIR Phase-I assignment on the same subject. The objective of this program was to develop and optimize CVD aluminum, iron and aluminum oxide coated iron powders and iron, aluminum coated aluminum oxide powders for thermal spray application and optimize the fabrication of this Iron Aluminide composites, and it's coatings and evaluate the performances of these new materials for potential use as high temperature, oxidation, corrosion and carburization resistant material aimed for future power generation and boiler equipment. The program developed CVD coated powders demonstrated the fabrication of oxide dispersion strengthened (ODS) Fe 3 Al composites with a tensile value of 121 KSI and oxidation, carburization and corrosion resistant thermal sprayed coating The Prime Contract manager was Mr.
