Definitions
- the invention relates to a composition of a NiCoCrAlY based alloy especially used for gas turbines, a powder, a coating and a component.
- This invention is to solve the problem by using recent research results and upgraded thermodynamic modelling to design an optimized and innovative NiCoCrAlX alloy coatings applied by means of thermal spraying in air, vacuum, or protected atmosphere, physical deposition, and plating on Ni or Co based superalloys.
- X is a combination of minor elements such as Y, Ru, Ir, Si, Hf, Ta and etc. instead of Yttrium (Y) in the current NiCoCrAlY coatings. It means that we will introduce other minor elements to replace part of Yttrium (Y) functions in order to keep Yttrium (Y) content low.
- NiCoCrAlX coatings are fabricated using Ruthenium (Ru) and Iridium (Ir) and reduces diffusion rate of Aluminum (Al) and forms diffusion barrier to minimize the interdiffusion between NiCoCrAlX coating and substrates. Ru addition increases mechanical durability of the coatings. Moreover, another approach in designing and manufacturing the innovative NiCoCrAlX coatings is reduce S content to ⁇ 10ppm to further increase coating lifetime.
- the coating thickness should be in the range of 30-800 ⁇ m depending on type of applications and application methods.
- the new NiCoCrAlX coating is Ni-based and possesses the preferred following composition (in wt%):
- a powder with this alloy composition can be mixed with a binder and/or refractory metals or ceramics if used as an abrasive coating.
- a metallic substrate like a nickel or cobalt based superalloy is used on which the inventive coating is applied on.
- the coating is applied especially by the thermal spray and electron beam vapor deposition processes.
- a layer system therefore at least comprises a metallic substrate, especially a Nickel based superalloy and at least a coating with the inventive alloy and optionally a ceramic layer on top the metallic bond and oxidation coating.
- the ceramic layer comprises preferably a Zirconia based composition, partly or fully stabilized.
