Functionally graded nickel-aluminide and iron-aluminide coatings produced via laser cladding
Journal of Materials Science, 1995Functionally graded nickel-aluminide and iron-aluminide in the form of superimposed clad layers up to ∼ 4 mm total thickness were produced on nickel and on iron based substrates, respectively. A continuous wave carbon dioxide laser and two separate powder feeders were employed. The processing parameters were: 1.8 kW laser power, 3 mm beam diameter, and

Surface morphology of platinum modified aluminide coatings
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1985The processing variables which lead to the rough, convoluted surface topologies of platinum modified aluminide coatings were studied. Platinum deposition techniques such as electroplating, ion plating, and sputtering were examined as were postplating diffusion treatments and aluminizing processes. It was found that while the initial Pt surface could be

Glass‐Ceramic Coatings for Titanium Aluminides
Journal of the American Ceramic Society, 1994Four glass‐ceramic coatings have been successfully developed to function as both hydrogen barriers and oxidation protection on super α‐2 titanium aluminide. The coefficients of thermal expansion (88 × 10 –7 /°C to 117 × 10 –7 /°C) of these coatings ...

Hot corrosion of yttrium-modified aluminide coatings
Materials Science and Engineering: A, 1989Abstract The beneficial effect of yttrium on the oxidation and hot corrosion resistance of electron beam-physical vapour deposition and low pressure plasma spraying overlay coatings has been confirmed by many studies. However, these coating processes have two disadvantages: (1) a restriction on the application of the coatings to complex geometries ...

Aluminide coatings prepared on Ti-6Al-4V substrate were able to improve oxidation resistance of the alloy under cyclic oxidation at 750°C both in dry and moist air conditions due to aluminide’s ability to form a stable alumina oxide scale.

Protection of titanium aluminides by FeCrAlY Coatings
Materials and Corrosion, 1997AbstractThe effectiveness of Fe+15%Cr+5%Al+0.3%Y coatings. produced by sputter ion plating, in improving the oxidation behaviour of γ‐2 Ti3Al at 800°C and γ‐TiAl at 900° and 1000°C. during cyclic exposures in air of up to 1000 hours duration, has been studied.

Oxidation-Resistant Aluminide Coatings on γ-TiAl
Oxidation of Metals, 2003The long-term application of TiAl alloys based on the γ-phase at temperatures above 750–800°C requires suitable surface coatings to provide the needed oxidation resistance. Without a coating, these alloys, containing large amounts of titanium, suffer from rapid oxidation attack at elevated temperatures.
