Thin Solid Films, 1977
Abstract The kinetics of phase layer growth during the aluminization of Fe and during subsequent heat treatment (homogenization) were investigated. Pack processing was employed for aluminization; the variables studied were temperature, time, amount of Al powder in the pack and the Al powder particle size.

Solidification of PTA aluminide coatings
International Journal of Materials Research, 2012Abstract Components can be protected with coatings tailored using plasma transferred arc to meet specific demands as mixtures of powders with an almost unlimited chemical composition can be processed. In this study, Ni, Fe and Nb aluminide coatings were processed from mixtures of elemental powders on steel substrates and on a Cu ...

Coating of Sic on Titanium Aluminide
MRS Proceedings, 1992Coating of silicon carbide on the surface of structural materials is being used in industry to improve the oxidation resistance and wear resistance properties. In this study, silicon carbide coatings were applied on titanium aluminide by both chemical vapor deposition and sputter deposition techniques.

Diffusion Model of Aluminide Coatings
CORROSION 2016, 2016Abstract The deleterious effects of corrosion can be mitigated by the application of coatings that can form a protective oxide layer. Halide Activated Pack Cementation (HAPC) is one such coating method in which a halide vapor is generated within a pack and undergoes reactions that ultimately result in the coating element, e.g., Al, being

The addition of zirconium to aluminide coatings: The effect of the aluminide growth mode
Surface and Coatings Technology, 2019Abstract Alumina-former coatings such as nickel aluminides have been the essential approach to combating the aggressive service environment of gas turbine hot section components. The positive effects of zirconium on the cyclic oxidation lifetime of aluminide coatings have been reported.

IN SITU MEASUREMENTS OF THE MECHANICAL PROPERTIES OF ALUMINIDE COATINGS
Surface and Coatings Technology, 1990Abstract A novel technique was used to measure the mechanical properties of surface diffusion coatings which, unlike overlay coatings, cannot be evaluated from bulk samples. Coatings on thin foil samples over a wide range of thicknesses were prepared and a technique related to a law of mixtures approach was used to obtain the elastic modulus, yield ...

Aluminide Coatings on Superalloys
1984Nickel and cobalt superalloys currently used in advanced gas turbines are almost always protected by coatings against high temperature oxidation and hot corrosion. Aluminide coatings are generally obtained by low or high activity pack cementation processes.

Microstructural Characterization of a Pt-Aluminide Coated IN738LC
Journal of Materials Engineering and Performance, 2001In this paper, the microstructural and chemical characterization of the IN738LC superalloy, coated with a Pt-Cr modified aluminide coating, is presented. The effects of aging in air at 850 °C on superalloy and coating microstructures were investigated. The growth of γ′ precipitates in IN738LC follows the Wagner-Lifshits model. The positive effect of Pt
