  • METHOD OF FABRICATING AMORPHOUS COATINGS ON CRYSTALLINE SUBSTRATES
    Publication number: 20120208045
    Abstract: An amorphous coating and method of fabricating the same on a substrate is disclosed. An amorphous iron based powder is located onto an aluminum alloy substrate. Pressure is applied to the powder and substrate at a processing temperature below a crystallization temperature of the powder. The powder and substrate are then spark plasma sintered for infiltrating the substrate material into the powder for resulting in a composite amorphous coating. The powder and substrate are then rapidly heated and held for 15 minutes at the processing temperature. The powder and substrate are then rapidly cooled at a cooling rate of approximately 150° C./minute. In one embodiment, the powder is comprised of Fe48Cr15Mo14Y2C15B6 alloy composition.
