Definitions
- the invention relates to a method for producing a corrosion-resistant and oxidation-resistant coating according to the preamble of claim 1. Furthermore, the invention relates to a device for producing a corrosion-resistant and oxidation-resistant coating according to the preamble of claim 14 and a component with such a coating according to the preamble of Claim 17.
- components When components, in particular components of gas turbines, are operated at high temperatures, their free surfaces are exposed to strongly corrosive and oxidizing conditions.
- such components can consist, for example, of a nickel-based or cobalt-based superalloy.
- the components are provided with coatings that are made from metal powders.
- a method for producing a corrosion-resistant and oxidation-resistant slip layer is known from DE 198 07 636 C1.
- a slip material is produced by mixing a binder solution with a starting powder containing aluminum or chromium and an addition powder containing at least one element made of aluminum, platinum, palladium or silicon, the addition powder not containing aluminum in the case of a starting powder containing only aluminum includes.
- the slip material thus produced is then applied to a component and then cured.
- a heat treatment following the hardening serves to diffuse the slip layer into the component.
- an addition powder and a starting powder are accordingly mixed and this mixture of different metal groups is applied to the component in one step.
- the present invention is based on the problem of a novel method and a novel device for producing a corrosion-resistant and to create oxidation-resistant coating and a component with such a coating.
- the method comprises the following steps: providing a paste which, in addition to a binder as the metal, contains only at least one metal from the platinum group; preferably diluting the paste; subsequent application of the preferably diluted paste to the component; then drying and heat treating the component coated with the paste; then alitizing the component coated with the paste.
- the paste contains platinum and / or palladium in addition to a binder as the metal.
- the following composition of the undiluted paste is particularly preferred: palladium in a proportion of 25-35% by weight, platinum in a proportion of 25-35% by weight, terpineol in a proportion of 15-25% by weight, resin ( Rosin) in a proportion of 10-20% by weight, and turpentine in a proportion of 1-5% by weight.
- the device according to the invention for producing a corrosion-resistant and oxidation-resistant coating is characterized by the features of the independent Claim 14 characterized.
- the component according to the invention is characterized by the features of independent claim 17.
- the surfaces of the component to be coated are blasted in order to obtain a shiny metallic surface on the component.
- any other method can of course be used to obtain a bright metallic surface.
- a paste is then produced or made available.
- the paste contains only at least one metal from the platinum group as metal.
- the paste can be a high-purity platinum paste that contains terpineol as a binder and only platinum as a metal.
- the composition of this high-purity platinum paste contains platinum in a proportion of 85 to 90% by weight and terpineol in a proportion of 10 to 15% by weight.
- platinum-palladium paste contains palladium in a proportion of 25 to 35% by weight, platinum in a proportion of 25 to 35% by weight, alpha terpineol in a proportion of 25 to 35% by weight, resin in a proportion of 10 to 20 % By weight and turpentine in a proportion of 1 to 5% by weight.
- the paste is then applied to the component. Before applying the paste, it is preferably diluted. This provides a dilute, thin paste that can be applied better to the component.
- a turpentine oil is suitable as a thinner. 2 to 4 ml, in particular 2.5 to 3 ml, of turpentine oil are preferably used as thinners per 5 grams of undiluted paste.
- the application is carried out by spraying, brushing, dipping, flooding, pouring or screen printing.
- the decision as to how the paste is applied to the component naturally also depends on the areas of the component to which the paste is to be applied. If the paste is to be applied to the entire component, dipping can be used. However, if the paste is only to be applied to selected areas, spraying or brushing is preferably used.
- the paste After the paste has been applied to the component or to corresponding sections of the component, the paste is cured or dried with a subsequent heat treatment.
- the heat treatment serves to diffuse the metals of the paste into the component. This can be done by diffusion annealing or vacuum annealing known from the prior art.
- the application, drying and heat treatment (diffusion) of the paste is repeated until a defined or desired coating of the component with the metals of the paste, ie with platinum and / or palladium, has been achieved.
- the paste can also be changed when repeating the application, drying and heat treatment.
- a paste containing exclusively platinum can be used
- a paste containing platinum and palladium in a subsequent first repetition step
- a paste containing exclusively palladium in a second repetition step.
- the coating can be precisely adjusted by suitable selection of the pastes and their combination in the repetition steps.
- the component coated with the paste is then alitated, ie coated with aluminum.
- the alitation can be carried out as gas diffusion alitation or powder pack alitation. The details of these alitation methods are familiar to the person skilled in the art addressed here. The alitation takes place only after the possibly repeated application, drying and heat treatment of the component coated with paste. Alitation can be carried out, for example, as shown in FIG. 1.
- 1 shows a component 10 coated with the paste, which is positioned in a device 11 according to the invention.
- Component 10 is a turbine blade.
- a so-called damper pocket area 12 of the turbine blade is to be provided with the coating.
- 1 shows, a blade 13 protrudes downward from the device 11 according to the invention, the damper pocket area 12 and a blade root 14 adjoining the damper pocket area 12 are located within the device 11 according to the invention ,
- the damper pocket area 12 of the component 10 to be coated and already coated with the paste is surrounded by an alitizing paste 15.
- the alitation paste 15 is covered by a covering powder 16, the covering powder 16 being in the form of Al 2 O 3 and being mixed with an activator. This can compensate for any loss of activator during the alitation process.
- the alitation is carried out at 700 ° C to 1 150 ° C in a protective gas atmosphere. Argon or helium can be used as the protective gas or inert gas.
- the alitation process shown in FIG. 1 is powder pack alitation. Due to the fact that the turbine blade 10 to be coated is positioned with the blade root 14 upward in the device 11, the alitizing paste 15 and the covering powder 16 act on the damper pocket area 12 of the turbine blade 10 to be coated under gravity.
- the inventive device 1 1 is designed as a capsule-shaped container made of sheet metal, which has a passage opening for the airfoil 13 in its bottom region. With the turbine blade 10 positioned in the container, the alitizing paste 15 and the cover powder 16 together with the activator can be introduced into the container. A charging device 17 is used for this purpose, which is arranged laterally next to the device 10 in FIG. 1.
- the airfoil 13 Below the airfoil 13 there is shown a highly schematic plan view of three devices 10 which are moved in the direction of the arrow 19 by conveyor devices 18 arranged laterally next to the devices 10 and are thereby moved by different stations 20, 21 and 22.
- the charging device 17 is positioned in the region of the station 20, as is done by the Arrow 23 is indicated.
- a furnace (not shown) is arranged for the alitation under a protective gas atmosphere.
- the paste with the metal or metals of the platinum group is not applied galvanically, but rather as a so-called slip layer by brushing, spraying or the like. This can be done with less effort and therefore has manufacturing advantages.
- the paste is applied exclusively to selected areas of the turbine blades, namely to the surfaces of the turbine blades that are not exposed to flow. It has been shown that in the so-called damper-pocket area of turbine blades, the coating according to the invention provides particularly effective protection against sulfidation or high-temperature corrosion. Cavities in cooling ducts of gas turbine blades can also be protected so well against sulfidation.
