Definitions
- the present invention relates to a slurry and a method for producing an aluminum diffusion layer.
- diffusion layers are also used in which chemical elements diffuse into the metallic surface to be protected and / or deposit on the surface in order to achieve an enrichment of the corresponding element on the surface to be protected.
- the diffused element then provides, together with the alloy constituents of the base material, corresponding properties in order to be able to operate the component at the desired high temperatures.
- a corresponding aluminum diffusion layer can be produced by the application of a slurry containing aluminum - containing powder particles which provide the aluminum for the diffusion process, wherein after drying and / or hardening of the slurry on the surface to be treated, the aluminum in the subsequent Diffusion annealing from the dried slurry layer diffused into the material.
- the application of such a slurry by brushing, dipping or spraying is very simple, so that such a method for producing an aluminum diffusion layer is technically interesting. In particular, components can also be easily repaired by the simple application.
- slips for carrying out an aluminum diffusion process have, in addition to aluminum-containing powder particles, a binder which essentially provides the liquid phase for forming the slip.
- a binder which essentially provides the liquid phase for forming the slip.
- such a slurry must also be designed to that effect be that the aluminum - containing powder is not oxidized by the binder as possible, so that the subsequent diffusion process is not complicated by the presence of alumina.
- additional oxides such as silica, or chromates, dichromates or phosphates in the aqueous and acidic binders.
- chromates have been used in the past, on the one hand to increase the corrosion resistance of the corresponding treated metallic component and on the other hand also to inhibit the oxidation of the metallic aluminum in the slurry.
- chromium (VI) compounds are extremely toxic and detrimental to health, so there is an increasing tendency to replace these components in the slip compositions. Examples of these are described in EP 2 060 653 A2, US Pat. No. 7,896,962 B2, WO 2010/134918 A1, US Pat. No. 7,270,852 B2, US Pat. No. 6,036,995 or WO 93/023247 A1.
- the silicon-aluminum alloys as particle constituents in a slurry and the use of glycols as organic binders to produce stable slips for the production of aluminum diffusion layers, which are free of toxic and harmful Cr (VI ) - get along connections.
- the silicon as an alloying component of the aluminum-containing powder and as an admixture in the form of silicon dioxide in particular a passivation function attributed to the metallic aluminum components.
- the slip should be easy to prepare and use.
- the invention proposes to provide a slip in which the stability of the slip composition and in particular of the metallic aluminum portions is increased by virtue of the fact that the aluminum-containing powder used in the slip for providing the aluminum has at least partially powder particles which coated with silicon.
- the proportion of silicon-coated powder particles can range from small proportions in the single-digit percentage range of the proportion of aluminum particles up to 100% proportion of the aluminum particles.
- the proportion of aluminum particles coated with silicon in the total number of aluminum particles can be selected in the range from 25% to 75%, preferably 40% to 60%, the percentages being able to relate to both weight and volume percentages.
- the silicon-containing aluminum-containing powder particles can be pure aluminum particles in the sense of a technically pure aluminum or aluminum alloy particles.
- the silicon-coated aluminum powder particles may be identical to or different from the other aluminum-containing powder particles of the slip composition with respect to the aluminum core in size, shape and composition.
- the slurry further comprises silicon-containing powder particles and a binder.
- the silicon-containing powder particles can in turn be formed from technically pure silicon powder particles or from powder particles of silicon alloys.
- these may be silicon alloys which have more than 50% by weight of silicon in the alloy composition or at least have silicon as the component with the highest proportion.
- the silicon-coated aluminum-containing powder particles can likewise be coated with technically pure silicon or with corresponding silicon alloys.
- the binder may comprise one or more of the group consisting of organic compounds, water, alcohols, glycol compounds, phosphates or phosphates and thickeners.
- the binder may comprise water, at least one glycol compound and at least one thickener.
- the thickener of the binder may comprise one or more components of the group comprising pectins, guar, locust bean gum, carrageenan, cellulose ethers, polyvinyl alcohol and silicates.
- the binder may have glycol ether acetate of from 90% to 100% by weight and thickeners of from 1% to 2% by weight.
- the total slip can then glycol ether acetate with 40 wt .-% to 50 wt .-%, thickener with 0.5 wt .-% to 1 wt .-%, coated and / or uncoated aluminum powder with 30 wt -. 40 wt. -% and silicon powder at 6 wt .-% to 7 wt .-% include.
- a method for producing an aluminum diffusion layer in which a slurry as described above is used is proposed.
- the corresponding slurry is applied, for example, by brushing, immersing the corresponding component in the slurry or by spraying the slurry onto the component surface at which the aluminum diffusion layer is to be produced.
- the so-provided slurry surface is subjected to a heat treatment at a first temperature to dry and / or cure the slurry. Thereafter, the diffusion annealing is performed to form the diffusion layer at a second temperature higher than the first temperature.
- the first temperature may be selected, for example, in the range of 100 ° C to 300 ° C, preferably 120 ° C to 220 ° C, while the second temperature in the range of 800 ° C to 1000 ° C, preferably 875 ° C to 925 ° C. can be chosen.
- the slurry Before the slurry is applied to the component surface to be treated, it can be blasted with particles in order to obtain a metallic and clean surface, alumina particles in particular being able to be used.
- a chromium (VI) -free slip composition which can be used in particular for the repair of high-temperature components of aircraft engines, such as turbine blades, comprises an aluminum powder and an aluminum powder with aluminum particles coated with silicon.
- the proportions of uncoated aluminum powder and aluminum powder particles coated with silicon may be in the ratio of (0 to 1): 1.
- the aluminum powders are incorporated together with a silicon powder in a binder consisting of water, a glycol compound and a thickening agent.
- a slurry comprises 40% to 50% by weight of glycol ether acetate, 0.5% to 1% by weight thickener, 30% to 40% by weight coated and uncoated aluminum powder, and the like 6 wt .-% to 7 wt .-% silicon powder.
- the binder may comprise from 90% to 100% by weight of glycol ether acetate and from 1% to 2% by weight of thickener.
- Such a slurry is sprayed or painted on a surface coated with aluminum oxide particles and tempered for drying and / or curing at about 150 ° C until the binder is dried and / or cured. If several layers of slurry applied, drying at about 80 ° C after applying one layer may be useful. Thereafter, diffusion annealing under a protective gas atmosphere, such as an argon atmosphere, is performed at 900 ° C for several hours to form an aluminum diffusion layer on the device surface, which provides oxidation protection to the device for high temperature applications.
- a protective gas atmosphere such as an argon atmosphere
