Description

Description
NiCoCrAlY-Alloy, a powder, a coating and a component
The invention relates to a composition of a NiCoCrAlY based alloy especially used for gas turbines , a powder, a coating and a component .
When further increasing engine ef ficiency, output power, availability, and reliability in the current gas turbine development , it is often limited by temperature capacity and li fetime of protective coatings for protection against hot corrosion and oxidation and bonding thermal barrier coating TBC on the hot turbine components . The used coatings were all developed more than 10 years ago and can not ful fil demands of further turbine development . In the MCrAlY coatings available today, one relies on Yttrium (Y) incorporation very much to have pegging and scavenge ef fects to increase oxidation and corrosion resistances of the coatings . However, it has recently been reported that Yttria inclusions in the protective aluminum oxide scale on top of MCrAlY provide fast oxygen di f fusion routes , and therefore , accelerate oxidation of the coating (Nij dam TJ, Sloof WG . Acta Materialia 2007 ; 55 : 5980 ) .
High content of Sul fur > l Oppm existed in the current MCrAlY shortens coating li fetime ( Smialek JL, Jayne DT , Schaef fer JC, Murphy WH . Thin Solid Films 1994 ; 253 : 285 ; and Smialek JL . Metallurgical Transactions A, Physical Metallurgy and Materials Science 1991 ; 22A: 739 ) . In addition, the increase in oxidation and corrosion li fetime of the MCrAlY coatings is often achieved in expense of their mechanical durability . The development of advanced turbines with flexible operations demands coatings withstanding operations with both higher temperature and longer time exposure and higher mechanical loadings .
This problem has not been solved yet . It is therefore aim of the invention to overcome the problems mentioned above.
The problem is solved by an alloy of claim 1, by a powder of claim 2, a coating by claim 3 and a layer system according to claim 4.
Further advantages of the invention are listed in the dependent claims which can be combined arbitrarily with each other to yield further advantages.
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. Introduction of Ruthenium (Ru) and Iridium (Ir) 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 pm depending on type of applications and application methods.
The new NiCoCrAlX coating is Ni-based and possesses the preferred following composition (in wt%) : Ni balanced,
25.7 % - 27.3% Cobalt (Co) ,
15.0% - 16.0% Chromium (Cr) ,
12.2% - 13.2% Aluminum (Al) , 0.3% - 0.5% Yttrium (Y) ,
2.5% - 3.5% Ruthenium (Ru) , and optionally
0.4% - 0.8% Silicon (Si) ,
0.4% - 0.6% Tantalum (Ta) ,
0.4% - 0.6% Molybdenum (Mo) .
This invention results in NiCoCrAlYRu, NiCoCrAlYRuSi , NiCoCrAlYRuTa, NiCoCrAlYRuMo, NiCoCrAlYRuSiTa, NiCoCrAlYRuSiMo, NiCoCrAlYRuTaMo , NiCoCrAlRuMoSiTa coatings with a higher temperature capacity, longer life, and larger mechanical durability than the NiCoCrAlY coatings available today .
A powder with this alloy composition can be mixed with a binder and/or refractory metals or ceramics if used as an abrasive coating.
For turbine application especially 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.
Even SLM, SLS or any AM technique is possible to apply coatings or to produce components of this alloy or used as repair material .
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 stabili zed .
