Abstract
Methods for coating substrates arc provided. A method for coating a substrate comprises disposing a coating on a substrate, where the coating exhibits a first strain tolerance; and treating the coating to enhance the strain tolerance of the coating to a second strain tolerance. The second strain tolerance is more strain tolerant strain than the first strain tolerance. Further, the step of treating comprises at least one of mechanical treating, chemically treating, thermally treating, and combinations thereof.
Description
The application is relevant with the U.S. Patent application US11/386424 of the application's common assignee with transferring of submission on March 22nd, 2006.
Technical field
The present invention relates to prepare the method for anti-strain coating, and the goods that generate thus.Particularly relate to the method that preparation has the anti-strain coating of " green compact " attitude, and the goods that generate thus.In addition, the invention still further relates to the method that preparation has the anti-strain coating of green compact attitude, and the goods that make thus, wherein said coating can be used as thermal barrier coating.
Background technology
Metal is understood oxidation, corrodes and is become fragile when being exposed to comparatively high temps (promptly more than or equal to about 700 ℃) and particularly being in the well-oxygenated environment.May result from gas turbine as being used for the gas turbine of power generation applications such as these environment with temperature and well-oxygenated environment.In technical field of power generation, known thermal barrier coating (TBC) can reduce the influence to metal parts of high temperature, well-oxygenated environment on putting on the metal turbine components time.
Thermal barrier coating generally comprises at least two integral parts, i.e. metal bonding coating and ceramic layer.Metal bonding coating can comprise anti-oxidation and/or etch-proof material, at least a such as but not limited in aluminium and the chromium.For example metal bonding coating can comprise chromium, aluminium, yttrium or their combination, and as MCrAlY, wherein M is nickel, cobalt or iron (having recorded and narrated some coated materials in people's such as the U.S. Pat 4,034,142 of Hecht and Gupta U.S. Pat 4,585,481).Metal bonding coating can apply (people such as Gupta has recorded and narrated the siliceous and hafnium particulate coated material that applies by plasma spraying) by hot-spraying techniques.
In addition, on the metal bonding coating, can apply the ceramic layer of thermal barrier coating.Applying method includes but not limited to as air plasma spray (APS) or electro beam physics vapour deposition currently known methodss such as (EB-PVD).
" green compact " attitude, by its definition in this application, be meant no matter the number of the component that applied and layer how, chemical constitution/the performance of coating all is " uncompleted " or without finally handling to reach the final expectation form with expectation chemical constitution/performance, also needs activation subsequently to handle the state that reaches expectation chemical constitution/performance.The final expected performance that is intended to realize the gained coating is handled in activation subsequently.Be defined herein as the further step that comprises that " finishing " described coating is required with aftertreatment.
All coatings with green compact attitude this do not complete or " green compact " attitude under all fragile.When being in the green compact attitude, these coatings may not have performance identical when being in final state with it.These performances comprise optics and/or machinery and/or the chemistry and/or the thermal characteristics of coating.This weakness makes coating can't be influenced the condition changing of coating usually when coating is in its final state just, changes sometimes or even for good and all.If attempt to use the material of performance green compact attitude to apply TBC, then can not obtain the performance of final expectation.
It is may be very expensive and/or be difficult to realize to obtain traditional coating method of the TBC of anti-the strain.Coating by EB-PVD method preparation can produce a kind of very anti-strained structure, but this method is very expensive and particularly may be unpractical for the element with very big or unique geometry.In addition, the coating with anti-complaisance need or carried out modification on the spot or after final processing, and the both is very expensive and difficult.In addition, the coating method of the known acquisition TBC of anti-the strain can not satisfy the needs that processing green compact coating produces anti-complaisance.
Therefore, exist and to benefit from the needs that apply the method for the TBC of anti-the strain on the structure of existence of TBC metal turbine part and other.In addition, also exist providing produce the needs that anti-complaisance obtains the coating method of the TBC of anti-the strain a kind of in coating, the separation by processing green compact coating.
Summary of the invention
A kind of method of coated substrate as institute of the present invention concrete manifestation, comprises being placed on the base material being coated with that wherein said coating shows the first anti-complaisance; Coating is handled so that the anti-complaisance of coating is brought up to the second anti-complaisance.The second anti-complaisance is than the more anti-strain of the first anti-complaisance.In addition, the treating step comprises at least a in mechanical treatment, chemical treatment, thermal treatment and the combination thereof.
Can above-mentioned and other characteristics of illustration by following detailed description.
Embodiment
Herein disclosed is the method for preparing anti-strain coating by first coated material of performance green compact attitude or non-final state.The term green compact are meant the state of material before for example handling by heat, mechanical means and/or chemical process.A kind of thermal treatment commonly used for raw material is sintering, but is not limited in this.
Implement as the present invention institute is concrete, can be following any coating by the coating that material obtained that shows the green compact attitude, but be not limited in these coatings: sol-gel, slurry and lotion.The method that is formed coating by the material that shows the green compact attitude includes but not limited to suspension method, spread coating, dip-coating, spraying and sedimentation.Implement as the present invention institute is concrete, electrochemical plating are methods that another material by performance green compact attitude forms coating.
