Definitions
- the invention relates to a process for plasma coating a turbine blade directed along a blade axis by means of thermal plasma spraying.
- the invention relates also a coating device for carrying out of the procedure.
- a coating process for plasma coating a turbine blade is apparent from EP 1 033 417 A1.
- One of the possible, applied to the turbine blade coatings consists of an MCrAlX alloy, where M stands for a or several elements comprising iron, cobalt or nickel, Cr for chromium, Al for aluminum and X for one or more elements the group comprising yttrium, rhenium as well as the elements the rare earths stand.
- This metallic layer is obtained by thermal spraying with the method VPS (Vacuum Plasma Spraying) or LPPS (Low Pressure Plasma Spraying) the turbine blade applied.
- the gas turbine blade is made in particular of a nickel or iron or cobalt base superalloy.
- the MCrAlX alloy is used in particular a corrosion and oxidation inhibition.
- a layer is usually followed by a heat post-treatment at.
- a process time of about 30 minutes while the postheat treatment the gas turbine blade a process duration of about Has 120 minutes.
- the plasma coating is done with a plasma gun or a plasma torch. Such a Plasma torch is also often before the coating process used to heat the component to be coated.
- the turbine blade to be coated is usually on one Turntable arranged while the plasma torch on one multi-axis robot is arranged. During the coating the turbine blade is at a coating temperature held from about 1100 ° K to 1200 ° K.
- U.S. Patent 4,683,148 discloses the use of two Plasma torches.
- DE 40 40 893 A1 discloses that more than two burners can be used to produce different, surprisingly advantageous structures by the development of vortex-like mixed microstructure. To what extent three burners can be controlled, about it no indications are given. The two or more burners are used to irradiate one and the same area with streams of particles containing different materials.
- the object of the invention is to specify a method for Plasma coating of a turbine blade, in particular an improved quality of thermal plasma spraying applied coating has resulted. Further task
- the invention is the specification of a coating device to carry out this process.
- the object directed to a coating apparatus is solved according to the invention by specifying a coating device for coating a turbine blade by means of a Method according to one of the possibilities described above.
- FIG. 1 shows a coating device 1.
- the coating device 1 has a coating chamber 3. With the coating chamber 3 is a pre-chamber 5 vacuum-tight connected. In the coating chamber 3 is one along a Blade axis 9 directed turbine blade 11 is arranged. The turbine blade 11 is on a in the coating chamber 3 leading blade manipulator 13 arranged. Via an expansion chamber connected to the coating chamber 3 15 also performs a burner manipulator 17 in the coating chamber 3. A first plasma torch 19 and a second plasma torch 21 are on a burner carrier 25th arranged. A third plasma torch 23 is on the burner manipulator 17 arranged. The three plasma torches 19, 21, 23 are decoupled from each other and thus independently controllable and movable.
- FIG 2 shows a structurally particularly simple way of installation the three plasma torches 19, 21, 23.
- the turbine blade 11 is thus a gas turbine blade made of a nickel or cobalt base superalloy base material 30. It has an airfoil 33, to which at her Blade tip a top platform 31 and blade foot side a foot platform 35 is adjacent. Between the platforms 31, 35, The blade 33 results in rounded areas 37, in which is especially the overspray when using only one Plasma torch can come as described above.
- the turbine blade 11 is attached to the blade manipulator 13 so by means of the blade manipulator 13 in a direction of rotation 43 is rotatable about the blade axis 9. moreover it is in an axial direction 41 along the blade axis. 9 axially displaceable.
- a first plasma torch 19 is injected along a first injection direction 67 on the turbine blade 11.
- the first plasma torch 19 is about a first axis of rotation 66 rotatable in the direction of rotation 65.
- a second Plasma torch 21 injects along a second spray direction 63 on the turbine blade 11.
- the second plasma torch 21st is along a second axis of rotation 62 in a direction of rotation 61 rotatable.
- the first plasma torch 19 is along a direction parallel to the blade axis 9 in the foot area the turbine blade 11, while the second Plasma torch 21 along this direction at the height of Blade tip of the turbine blade 11 is arranged.
- the first injection direction 67 forms with the second injection direction 63 an angle ⁇ , which is greater than 90 °. In this configuration serves the first plasma torch 19 of a coating the top platform 31, while the second plasma torch 21st a coating of the foot platform 35 is used.
- a third Plasma torch 23 Approximately at the height of the intersection of the first injection direction 67th with the second injection direction 63 and on the opposite Side of the turbine blade 11 is arranged a third Plasma torch 23.
- This third plasma torch 23 injects along a third spraying direction 53 onto the turbine blade 11.
- the third plasma torch 23 is along a Rotation axis 56 rotatable about the rotational direction 55.
- the turbine blade 11 Before coating the turbine blade 11 with a Coating 81, preferably an MCrAlX oxidation corrosion protection layer, the turbine blade 11 is heated. This happens in particularly uniform way through all three plasma torches 19, 21, 23 at the same time. After reaching the desired temperature the coating material is applied, wherein as described, the first plasma torch 19 and the second Plasma torches 21 serve the coating of the platforms 31, 35, while on the third plasma torch 23, a coating of the blade 33 is made.
- a Coating 81 preferably an MCrAlX oxidation corrosion protection layer
- the blade manipulator 13 is along the axial direction 41 movable, wherein the burner manipulator 17 synchronized can move so that from the burner 23 always the same Radius on the turbine blade 11 is coated.
- the Burner 19, 21 are decoupled from this synchronous movement.
- FIG. 3 shows a modification of the coating device 1 of Figure 2, this modification the third plasma torch 23 concerns. This is now in one direction 51 perpendicular to the plane E movable through the blade axis 9 and the third injection direction 53 is fixed. Furthermore, the third plasma torch 23 is also in its distance to the turbine blade 11 via a mobility along the third injection direction 53 movably arranged. While the axis of rotation 56 of the third plasma burner 23 according to the Arrangement in Figure 2 parallel to the blade axis. 9 was aligned, it is now along the spray direction 53 and thus directed perpendicular to the blade axis 9. The rotation axis 56 lies in the plane E.
- FIG. 4 shows a joint mobility the first plasma torch 19 and the second plasma torch 21 by means of a drive unit 71, the one Carrier 72 for the first and second plasma torch 19, 21 in parallel moved to the blade axis 9.
- a chain 73 moved parallel to the blade axis 9.
