Definitions
- the invention relates to a gas collection pipe carrying hot gas a gas turbine between the combustion chamber and the Turbine blade inlet flange from one highly warm and corrosion-resistant base metal M (Substrate) with one applied on the inside High temperature corrosion and oxidation layer.
- the two-arm gas collection or downpipe between the combustion chamber housing and the Inlet connection of the turbine blades in hot operation extreme stress and increased wear exposed to temperature, pressure and corrosion.
- the combustion air is high in a compressor Pressure compresses, a substantial part of which two combustion chambers for combustion, a smaller one Share used to cool the hot metal parts becomes.
- the substantial amount of O 2 in the air is oxidized by burning a carbon carrier, nitrogen remains in the exhaust gas as ballast and is also brought to high temperatures by the combustion process at high pressure and flows out of the combustion chambers into the downpipe and from there into the turbine on the turbine inlet blades and sets them in increased rotation.
- the gas collecting or downpipe is made of an iron-nickel base material. This is due to high pressure and especially due to an increased gas temperature attacked, oxygen affecting the metal surface oxidized.
- the alloying elements of the Ni-based alloy like Aluminum, chromium or the like reduce one further oxidation through the formation of solid oxide layers.
- This passive oxide layer does not prevent Penetration of nitrogen so that over time the nitrogen with the above-mentioned alloying elements Nitrides or carbon nitrides can form whose Formation thermodynamically due to the higher pressure of the gas is favored.
- AIN nitrides
- Cr-carbon nitrides can be formed.
- This mechanism does not only take place in the combustion chamber of the downpipe, but also in the cooling air charged external surface, which is not always so can be cooled far that the said gas metal reaction cannot take place.
- the HKO layer develops through the increased Cr and Al contents in connection with yttrium have a large resistance potential against oxidation and nitriding and thus an increased high temperature corrosion and -oxydationswiderstand.
- TBC Thermal Barrier Coating
- the thermal barrier coating is a plasma spray coating system, consisting of an adhesive layer and a ceramic top layer, which the thermal insulation of the Layer system causes.
- the adhesive layer serves in addition to the liability of the Top layer also to avoid high temperature corrosion / oxidation of the material. To both functions To be able to optimally fulfill this adhesive layer from a two-layer MCrAlY layer, one so-called adhesive layers A and B.
- the adhesive layer A is a ductile MCrAlY layer with lowered chrome and aluminum content to long term to ensure optimal adhesion to the substrate.
- the adhesive layer B is a MCrAlY layer with an increased Chromium and aluminum content. This will next to the increased high temperature corrosion and oxidation resistance an embroidery of the base material prevented.
- the top layer consists of a ZrO 2 -Y 2 -O 3 ceramic and, due to its lower thermal conductivity, provides thermal insulation for this layer.
- WO 89/07159 describes multiple protective layers for Metal objects, in particular gas turbine blades, known. Based on the knowledge that there are two different Corrosion mechanisms exist for life such objects are important specified two superimposed protective layers, of which the inner against corrosion attacks Protects temperatures from 600 ° C to 800 ° C and the external against attacks at temperatures from 800 ° C to 900 ° C is optimized. In addition, as the extreme A thermal barrier layer is also present on the coating layer his. Preference is given to the first coating layer a diffusion layer with a chromium content greater than 50% and an iron and / or manganese content of more an MCrAlY layer as 10% and as a second coating layer with z. B. about 30% chromium, about 7% aluminum and about 0.7% yttrium by plasma spraying reduced pressure is applied.
- WO 91/02108 is a protective coating, in particular known for gas turbine components, the good Corrosion properties in the temperature range of 600 up to about 1150 ° C.
- the protective coating contains (in percent by weight): 25 - 40% nickel, 28 - 32% Chromium, 7 - 9% aluminum, 1 - 2% silicon, 0.3 - 1% Yttrium; Balance cobalt, at least 5%; and inevitable Impurities. Different choice components can be added. By adding rhenium the properties of the protective coating be improved. This effect already occurs low additives. A range of is preferred 4 - 10% rhenium.
- the coatings can be by plasma spraying or Evaporations (PVD) are applied and are special suitable for gas turbine blades made of a super alloy based on nickel or cobalt. Others too Gas turbine components, in particular with gas turbines high inlet temperature of e.g. B. above 1200 ° C, can be provided with such protective coatings become.
- WO 96/34128 is a nickel or cobalt metal alloy known to have a protective layer against increased temperature and corrosion attacks hot gases applied from the combustion chamber of a gas turbine become.
- the three-layer protective layer consists of one first binding layer made of an MCrAlY composition compared to the base metal to be protected and one second anchoring layer opposite the outer one Oxide layer.
- a metal substrate is based on WO 96/34129 a nickel or cobalt alloy known to the one Protection system against increased temperature, corrosion and Erosion is applied.
- the protection system consists of an intermediate layer, consisting of a binding layer against which Ni substrate and an anchoring layer opposite the outer ceramic layer based on zirconium oxide.
- the outer ceramic layer serves as a thermal insulation layer.
- the object of the invention is the gas metal reaction on the hot inner surface of the mixing tube prevent or delay so far that the life of this part is considerably extended and the gas metal reaction also on the cooled to prevent the outer surface of the collecting mixing tube or delay so far that the lifespan of the Parts will be extended considerably.
- the surfaces of the hot gas are therefore Gas collecting or downpipe between Combustion chamber housing and turbine both from the inside and also from the outside with a high temperature corrosion and -oxidation layer provided, which consists of a single layer MCrAlY layer exists, so that a gas metal reaction of nitrogen with the metal of the gas manifold is prevented or largely delayed.
- the high temperature corrosion and oxidation layer containing 31% Cr, 11% Al, 0.6% Y and Residual nickel therefore has such high Cr and Al contents that a large resistance potential in the protective layer against oxidation and nitriding and thus an increased High temperature corrosion and oxidation resistance given is.
- the coating of the complete downpipe - inside and outside - done manually or as program-controlled MCrAlY plasma coating in a layer thickness of 60 ⁇ 40 ⁇ m.
- the inner cone of the gas manifold becomes at the transition the gas turbine also with a one-sided thermal insulation layer lined.
- This insulation layer is known to consist of a two-layer MCrAlY layer - layers A and B - and one ceramic top layer.
- the adhesive base layer A is a ductive MCrAlY layer with a reduced chromium and aluminum content by one Adhesion of this layer to the base material of the To ensure gas manifold.
- the adhesive base layer B corresponds to the Composition of high temperature corrosion and oxidation coating.
- the thermal insulation layer is complemented by a Ceramic top layer (top coat) based on zirconia due to their low thermal conductivity, thermal insulation causes.
- the thermal insulation layer exposes itself a layer thickness of 60/60/250 ⁇ m together.
- the gas manifold is also on the two Entry openings with an anti-wear coating Mistake.
- Fig. 1 shows a multidimensional view of the Gas collecting or downpipe (1) with in the upper area arranged inlet openings (2) for the hot gas the two combustion chambers, not shown.
- the gas collecting tube (1) is both outside and inside with a high temperature corrosion and oxidation layer (4) lined.

- Fig. 2 shows a section through the wall of the Down pipe with the high temperature corrosion and Oxidation (HKO) layer.
- HKO high temperature corrosion and Oxidation
- FIG 3 shows a section through the gas collecting tube (1), that between the combustion chamber housings, not shown and a downstream turbine is.
- the hot and corrosive exhaust gas leaves the mixing tube of the Combustion chamber and flows through the inlet opening (2) into the gas collection tube (1), which is not within a illustrated housing between the flanges of the Combustion chamber housing and the flanges of the turbine is arranged.
- Base metal (9) of the gas manifold (1) is outside cooled by a cooling medium.
