Definitions
- the present invention relates to the technology of power plants. It refers to a power plant component according to of claim 1.
- the steel material that is used for compressor blades in gas turbines suffers from water droplet erosion and corrosion pitting induced cracking as well as fouling.
- On-line and off-line washings are performed in required intervals in order to improve the performance of the turbine.
- the off-line washing intervals can be extended; less blade erosion occurs during on-line washing and in high fogging systems compressor efficiency is increased.
- gas turbines are used in environments, which are highly corrosive for instance in industrial areas or coastlines and therefore undergo a heavy pitting corrosion.
- Document US 2010/0247321 A1 presents an article including a metallic substrate.
- the article further includes a sacrificial layer disposed on a surface of the substrate and an anti-fouling layer disposed on the sacrificial layer.
- the anti-fouling layer includes a metal-polymer composite.
- An article including an anti-fouling layer having a nitride is also presented.
- Document US 2009/0176110 A1 discloses a coating system and process capable of providing erosion and corrosion-resistance to a component, particularly a steel compressor blade of an industrial gas turbine.
- the coating system includes a metallic sacrificial undercoat on a surface of the component substrate, and a ceramic topcoat deposited by thermal spray on the undercoat.
- the undercoat contains a metal or metal alloy that is more active in the galvanic series than iron, and electrically contacts the surface of the substrate.
- the ceramic topcoat consists essentially of a ceramic material chosen from the group consisting of mixtures of alumina and titania, mixtures of chromia and silica, mixtures of chromia and titania, mixtures of chromia, silica, and titania, and mixtures of zirconia, titania, and yttria.
- EP 2 374 916 A1 describes a process for providing a protective coating to a metal surface which comprises applying a nickel or tantalum plate layer to the surface and dispersing particles of a hard material such as diamond, alumina, vanadium nitride, tantalum carbide and/or tungsten carbide within the nickel or tantalum plate layer as the plating is occurring.
- a hard material such as diamond, alumina, vanadium nitride, tantalum carbide and/or tungsten carbide within the nickel or tantalum plate layer as the plating is occurring.
- EP 2 060 328 A2 discloses a method of forming a composite powder coating which comprises depositing multiple layers of a powder coating composition onto a substrate, wherein adjacent layers are formed of a different powder coating composition; and curing the multiple layers of the powder coating composition in a single thermal curing step.
- the layers can be used to protect power generation equipment from aqueous corrosion, particle erosion, slurry erosion, fretting, and fouling.
- US 8,007,246 B2 provides a method of fabricating a component for a gas turbine engine is provided.
- the method includes applying a bond coat to at least a portion of the component, applying a dense vertically cracked (DVC) thermal barrier coating to at least a portion of the bond coat using a spray mechanism positioned a first distance from the component, and overlying at least a portion of the DVC thermal barrier coating with a soft coat thermal barrier coating using a spray mechanism that is positioned a second distance away from the component, wherein the second distance is greater than the first distance to facilitate adherence of the soft coating thermal barrier coating to the DVC thermal barrier coating.
- DVC dense vertically cracked
- the power plant component according to the invention comprises a substrate the surface of which is coated with a functionally graded coating of a predetermined thickness, with anti-erosion, anti-corrosion and anti-fouling properties.
- said functionally graded coating comprises a corrosion resistant first means, and an erosion resistant and hydrophobic second means
- said functionally graded coating is a composite coating consisting of a single layer, whereby the concentration of said corrosion resistant first means and the concentration of said erosion resistant and hydrophobic second means vary gradually along the thickness of said composite coating, whereby the concentration of said corrosion resistant first means varies gradually from a high concentration at the inner side of said composite coating to a low concentration at the outer side of said composite coating, and that the concentration of said erosion resistant and hydrophobic second means varies gradually from a low concentration at the inner side of said composite coating to a high concentration at the outer side of said composite coating.
- said substrate is a metal or composite polymer substrate.
- said corrosion resistant first means comprises a metal, ceramic, cermet and/or polymer matrix, in which particles are embedded, whereby the concentration of said particles varies gradually from a high concentration at the inner side of said composite coating to a low concentration at the outer side of said composite coating.

Description
- The present invention relates to the technology of power plants. It refers to a power plant component according to of claim 1.
- Several power plant components such as compressor blade, steam turbine blade and wind blade undergo water droplet erosion, corrosion and fouling. The best way of protection against these damages is protecting blades (or other components) using multi-function composite coatings.
- The steel material that is used for compressor blades in gas turbines suffers from water droplet erosion and corrosion pitting induced cracking as well as fouling.
- On-line and off-line washings are performed in required intervals in order to improve the performance of the turbine. By applying functional composite coatings on compressor blades, the off-line washing intervals can be extended; less blade erosion occurs during on-line washing and in high fogging systems compressor efficiency is increased.
- In addition gas turbines are used in environments, which are highly corrosive for instance in industrial areas or coastlines and therefore undergo a heavy pitting corrosion.
- The presence of aerosols and soot in atmosphere causes fouling formation on the blades that worsens the corrosion.
- The existing solutions do not address the main three properties of erosion, corrosion and fouling, especially fouling is not addressed or it is very vague. Or the coating considered as anti-fouling is not erosion resistant and therefore anti-fouling property will be lost during operation. Or coating application methods such as sputtering or CVD and PVD are used which are not cost effective or difficult to apply.
