Definitions
- the present invention relates to a method for producing a coating by thermal spraying, in particular by plasma spraying, in which a component, in particular a bore of an internal combustion engine, e.g. is made of a light metal, is coated with an alloy, preferably with an iron alloy, wherein a plasma nozzle, which is supplied to a plasma gas and a transport gas is rotated about a wire and movable along a longitudinal axis of the bore, so that the bore from the inside and around coated in the axial direction of the bore.
- a plasma nozzle which is supplied to a plasma gas and a transport gas is rotated about a wire and movable along a longitudinal axis of the bore, so that the bore from the inside and around coated in the axial direction of the bore.
- EP 1 967 601 A2 From EP 1 967 601 A2 it is known that e.g. To coat an aluminum engine block, in particular its cylinder bore with an iron alloy while performing the arc wire spraying.
- EP 1 967 601 A2 proposes to use an iron alloy which contains inter alia 5 to 25% by weight of chromium. It is essential in the EP 1 967 601 A2, that the molten iron also an additional powder, namely Borcabid is supplied.
- the arc wire spraying method of EP 1 967 601 A2 is the so-called TWAS method, in which two wires are fed to a spray head in such a way that power is transmitted to the wires. When the two wires touch each other, a permanent short circuit causes an arc to melt the wires. Behind the nozzle is a nozzle from which compressed air or an inert gas such as nitrogen escapes. This gas stream atomizes the molten iron alloy and supplies it with the molten borocabid powder to the surface to be coated.
- DE 44 1 1 296 A1 and DE 44 47 514 A1 deal with coatings by means of plasma spraying, although a metal powder or a filler wire are melted, and wherein the material mixture nitrogen by means of metallic nitrogen compounds is added to harden the coating.
- EP 0 858 518 B1 deals with a method for producing a sliding surface on a light metal body by thermal spraying a coating of steel and molybdenum, wherein the wear layer is applied by means of plasma spraying.
- EP 0 858 518 B1 describes that a mixture of steel powder with molybdenum powder is used.
- EP 1 340 834 B1 a method for producing a cylinder tread layer is described. In this case, a rotating plasma spraying device is used, so that the engine block to be coated can rest during the coating.
- the proportion of pores may be dependent on e.g. be influenced by the particle size of the coating powder targeted.
- FR 2 924 365 A1 also deals with the plasma spraying of interior walls, whereby an additional spray powder is also used.
- the capacity of the pores in the coating should be different, due to a change in the plasma spray parameters, e.g. the size, the hardness, the speed and the preheating temperature of the metal particles, or the metal powder should be possible.
- Today's internal combustion engines or their engine blocks can be made of a metal or a light metal such. Cast aluminum or magnesium, in particular light metal blocks have on their cylinder bores an iron or metal layer.
- the metal layer may be thermally sprayed. As thermal spraying methods, the above-mentioned methods are known.
- the relevant prior art of the present invention includes the so-called PTWA inner transfer process (Plasma Transferred Wire Are).
- PTWA inner transfer process Pulsma Transferred Wire Are
- bores cylinder bores
- the inner wall is thus completely coated all around and in the axial direction.
- It is essential in the PTWA process that no metal powder is sprayed, but a homogeneous wire is melted and its melt droplets are transported to the inner wall to be coated and hit here, so that the coating is formed. So here only a single wire-shaped spray additive is supplied.
- the plasma strikes the preheated, wire-shaped spray additive.
- the plasma gas is usually an argon-hydrogen mixture.
- PTWA As transport gas or atomizing gas, air or compressed air is used in the PTWA process.
- the layers produced by this process are characterized by a low porosity.
- the PTWA internal coating process has hitherto proven itself in the interior coating of cylinder bores, in particular of light metal blocks.
- the coating usually has pores which reduce the friction between the piston rings and the cylinder surface because lubricant can accumulate in the pores.
- EP 1 340 834 B1, EP 0 858 518 B1 and FR 2 924 365 A1 deal with an influence on the occurrence of pores in the coating.
- the invention is based on the object to provide a method of the type mentioned above, with which a coating improved in this respect can be produced.
- the gas flow it may be the plasma gas flow and / or the transport gas during the coating process at different positions along the longitudinal axis of the inner wall to be coated different amounts. If the flow rate of the gases varies over the axial length of the bore, different pore levels in the coating may occur depending on the flow rate amount. With the invention it has been advantageously recognized that a low gas flow rate produces a high pore content and a higher gas flow rate produces a small proportion of pores in the coating.
- the inner coating can still be post-processed, for example honed, and / or lapped, to name just a few post-processing processes merely by way of example.
- pistons are moved back and forth in a known manner.
- the piston rings are in contact with the cylinder surface, ie with the coating.
- the gas flow rate in the region of top dead center has a low amount, so that forms a high percentage of pores.
- Even in the bottom dead center such a high percentage of pores in the coating can be provided.
- the pore content may be reduced, so a higher flow rate can be set.
- the plasma spraying device can be moved back and forth along the bore in the axial direction.
- a circumferential inner coating can be produced together with the rotation. It can be started at an upper portion of the bore with the injection process.
- the coating may have a small pore content, therefore the flow rate of the gas is limited to a high amount of e.g. 1 1001 / min can be set.
- the plasma spraying device When the plasma spraying device is moved along the longitudinal axis towards the opposite end of the bore and reaches the top dead center region, it is convenient to reduce the flow rate and reduce it to a low amount of e.g. 4501 / min to produce a high porosity in the coating.
- a lower flow rate causes a lower impact energy of the molten wire droplets on the inner wall.
- a flow rate of a high amount e.g. 1 1001 / min, so that a coating with a low pore content is also achievable.
- a high flow rate the remainder of the inner wall of the bore can now be coated.
- the aim of the invention is therefore that over the axial length of the hole to be coated coating areas with different Pore shares are achievable, in particular, the top dead center has a particularly high percentage of pores. This is achieved in the invention via the variable flow rate of the gas, wherein in the top dead center, a low flow rate of eg 4501 / min is adjustable.
- the transport gas is variably adjustable in its flow rate. It is also conceivable if the plasma gas can be variably adjusted together with the transport gas or per se in its flow rate.
- the variable adjustment of the flow rate can be achieved via a control element which receives corresponding signals in order to set the desired or most advantageous flow rate for the respective position of the spray device along the bore to be coated.
- the control may be in a preferred embodiment, a fast-switching solenoid valve, which preferably controls the flow infinitely.
- the control is arranged in the respective supply line of the respective gas.
- inventive method can also be used for coating other components.
- Fig. 1 is a schematic view of a plasma spraying apparatus for carrying out the method.
- Fig. 2 is a schematic section through a cylinder bore with an after
- FIG. 1 shows a nozzle unit 1 of a PTWA internal coating device.
- the PTWA (Plasma Transferred Wire Are) coating system is a system for coating bores, in particular cylinders in engine blocks of internal combustion engines.
- the nozzle unit 1 consists of a cathode 2, a plasma nozzle 3, and the electrically conductive alloy wire 4 as Anode which is fed perpendicular to the plasma nozzle 3.
- Tungsten is preferably used as the material for the cathode 2, which may be doped with thorium, for example.
- the plasma gas 5, for example a mixture of argon and hydrogen, is supplied through bores located in the nozzle body 6 and located tangentially to the circumference.
- the cathode holder 7 insulates the cathode 2 with respect to the nozzle body 6.
- the alloy wire 4 is rotatably guided in the wire feed 15 and longitudinally displaceable.
- the process is started by a high-voltage discharge which ionizes and dissociates the plasma gas 5 between alloy wire 4, nozzle body 6 and cathode 2.
- the plasma thus generated flows through the plasma nozzle 3 at high speed.
- the plasma gas 5 is transported toward the alloy wire 4 fed continuously perpendicular to the nozzle 3, whereby the electric circuit is closed.
- the plasma jet 8 emerging from the plasma jet 3 is supplied with a transport gas 9 or an atomizing gas 9 via feed channels 10 and auxiliary nozzles 11.
- the melting and the atomization of the alloy wire 4 are influenced by two phenomena.
- the wire 4 is on the one hand by high currents, typically 65-90 amps, resistance heated.
- the impact of the plasma jet 8 on the preheated wire 4 causes its melting at the wire end 12.
- a plasma is generated within the plasma nozzle 3 by means of high-voltage discharge.
- a targeted nitrogen gas flow so the transport gas 9 along the discharge path transports the plasma and the molten spray material 13 to the surface 14 of the cylinder bore to be coated.
- FIG. 2 shows a schematic section through a cylinder bore 16 with a coating 14, wherein the coating 14 has been produced with a flow rate or gas flow rate which has been changed over the axial length X.
- the coating is principally and merely by way of example divided into five regions, the dimensions of the regions shown, that is to say the axial extent thereof, being only an example.
- the injection process according to the PTWA internal coating process has started in an upper ceiling area 17. The spraying device was moved from the upper ceiling area 17 towards the opposite end 18, the nozzle unit 1 rotating as described above.
- an upper dead center area 19 which adjoins the upper ceiling area 17.
- the upper dead center region 19 is adjoined by a middle region 20, to which a lower dead center region 21 adjoins.
- a lower foot area 22 connects.
- In the upper deck area 17 but also in the middle area 20, and also in the lower foot area 22 was injected at a high flow rate, which is why the coating in the respective area has a low pore content.
- the region 21 is optional, so that the coating may also have only the regions 17, 19 and 20, the middle region 20 being guided to the end 18, and having been injected at a high flow rate, and therefore the coating then in the respective region 17 and 20 (until the end 18) may have a low pore content.
