Microstructure and oxidation resistance of Pd+Zr and Pd+Hf co-doped aluminide coatings deposited on Mar-M247 nickel superalloy [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2023
Pd+Zr and Pd+Hf co-doped aluminide coatings were deposited on the nickel superalloy Mar-M247 by palladium electroplating followed by zirconization-aluminization or hafnization-aluminization processes.

Thermal cyclic resistance and long term inter-diffusion properties of slurry aluminide coatings modified with Si

Results in Surfaces and Interfaces, 2022
High temperature oxidation resistant aluminide coatings fail due to their inability to maintain a protective scale. The corresponding mechanism of protection is based on of forming a thin Al2O3 layer, which depends on the availability of Al at the ...

Effect of Ni-Based Superalloy on the Composition and Lifetime of Aluminide Coatings. [PDF]

Materials (Basel)
Aluminide coatings on nickel-based superalloys were synthesized via a high-temperature “clean” low-activity vapor-phase process. This process is environmentally friendly and meets manufacturers’ environmental protection requirements ...

Effect of water vapor content on corrosion performance of aluminide coatings on TP347H in a simulated biomass combustion environment

Journal of Materials Research and Technology, 2022
Large numbers of power plants are taking biomass energy to replace fossil fuels. However, biomass combustion process deposits a substantial amount of potassium chloride in the boiler pipe, which causes high-temperature corrosion.
