Definitions
- the invention relates to a wear protection coating, in particular an erosion protective coating, preferably for gas turbine components, according to the preamble of patent claim 1.
- Components subject to flow mechanics such as gas turbine components, are subject to wear as a result of oxidation, corrosion and erosion. Erosion is a wear process caused by solids moving in the gas flow.
- wear protection coatings are required which protect the components against wear, in particular against erosion, corrosion and oxidation.
- EP0674020B1 a multilayer, erosion-resistant coating for the surfaces of substrates is known.
- the erosion-resistant coating disclosed therein provides a wear-resistant coating consisting of multiple multilayer systems applied repetitively on the substrate to be coated.
- the multi-layer systems applied in repetition are each formed from two different layers, namely on the one hand of a layer of a metallic material and on the other hand of a layer of titanium diboride.
- EP0366289A1 discloses another erosion resistant and corrosion resistant coating for a substrate. Also according to EP 0366289 A1, the wear protection coating is formed from a plurality of multilayer systems applied in repetition on the substrate to be coated, each multilayer system again consisting of two different layers, namely a metallic layer, for example titanium, and a ceramic layer, for Example of titanium nitride.
- EP0562108B1 Another erosion-resistant wear protection coating is known from EP0562108B1.
- the wear protection coating disclosed there is again several formed in repetition on a multi-layer system applied to a substrate to be coated.
- FIG. 4 of EP0562108B1 discloses a wear protection coating formed from a plurality of repeatedly applied multilayer coating systems, each multilayer coating system consisting of four layers.
- the wear protection coatings are preferably applied by vapor deposition to the surface of a component to be coated and thus protected, whereby the roughness on an outer, flow-relevant surface of the component can be increased by vapor deposition of a wear protection coating.
- the increase in roughness is aerodynamically unfavorable, since flow losses can form.
- an increase in roughness can result in faster and more severe contamination, as deposits of contaminants on rough surfaces can more readily deposit.
- An increased roughness also causes an accelerated attack of the surface of the component in case of erosion by hard particles. There is therefore a need to improve wear protection coatings.
- the present invention is based on the problem to provide a novel anti-wear coating.
- an outer layer is formed as a smoothing layer, which compensates for unevenness or roughness and / or defects of the wear protection coating.
- the present invention it is proposed to apply to the actual wear protection coating on the outside a smoothing layer which compensates for unevenness or roughness or even defects of the wear protection coating.
- This provides a highly smooth superfinish surface which results in a reduction in aerodynamic losses and contamination of the coated component counteracts.
- the erosion resistance can be improved.
- an improvement in the oxidation and corrosion resistance is expected.
- the smoothing layer is formed as a sol-gel layer, which has a thickness in the order of the unevenness or roughness and / or defects to be compensated.
- FIG. 1 shows a highly schematic cross-section through an inventive wear protection coating according to an embodiment of the invention.
- the present invention relates to a wear protection coating, in particular an erosion protection coating, for a surface to be protected of a fluid mechanical stressed component, in particular a component of a gas turbine, such. B. a blade or vane of a gas turbine.
- FIG. 1 shows a highly schematic cross-section through a wear-resistant coating 10 according to the invention, which is applied to an outer surface 11 of a fluidically stressed component 12, in particular a gas turbine blade.
- An outer layer of the wear protection coating 10 according to the invention is designed as a smoothing layer 13, wherein the smoothing layer 13 compensates for unevenness or roughness and / or imperfections of the actual wear protection coating.
- the smoothing layer 13 in this case has a thickness which is in the order of magnitude of the unevenness or roughness and / or defects to be compensated.
- the smoothing layer 13 preferably has a thickness between 1 .mu.m and 10 .mu.m.
- the thickness of the smoothing layer is between 5 ⁇ m and 10 ⁇ m.
- the thickness of the smoothing layer 13 may also be between 1 ⁇ m and 5 ⁇ m.
- the smoothing layer 13 forms the outer layer or layer of the wear protection coating according to the invention, wherein in the exemplary embodiment of FIG. 1 two multilayer systems 14, 15 are applied to the surface 11 of the component 12 to be coated, and wherein each multilayer system 14 15 comprises a relatively soft, metallic layer 16 and a relatively hard ceramic layer 17.
- the outer smoothing layer 13 is applied to the outer, relatively hard, ceramic layer 17 of the outer multilayer system 15.
- the smoothing layer 13 of the wear protection coating according to the invention is designed as a sol-gel layer.
- a liquid phase, a so-called SoI, z. B. by dipping, spraying or brushing applied to the outer layer 17 of the outer multi-layer system 15 and then dried by tempering and cured.
- the liquid phase namely the sol
- transforms into a solid phase into a so-called gel.
- the drying and curing can be combined with a heat treatment.
- the application of the smoothing layer 13 formed as a sol-gel layer to the outer hard layer 17 of the multilayer system 15 has the advantage that the relatively hard layer 17 provides a supporting effect for the relatively thin sol-gel layer and thus the smoothing layer 13, which in particular supports the connection of the smoothing layer 13 under mechanical stress.
- the smoothing layer 13 there is preferably provided a silicate-based or carbon-based or metal oxide-based or polymer-based sol-gel layer. It is therefore within the meaning of the present invention as an outer layer of a wear protection coating to provide a smoothing layer 13, which compensates for unevenness or roughness and / or defects of the actual wear protection coating.
- the smoothing layer 13 is preferably formed as a sol-gel layer, with a thickness which is in the order of the unevenness or roughness and / or defects to be compensated.
- the smoothing layer 13 is used when the wear protection coating is formed from a plurality of multilayer coating systems, wherein the smoothing layer is then applied to the outer layer of the outer multilayer coating system.
