Definitions

  • the present invention relates to a process for producing a coating by thermal spraying, in particular by plasma spraying, in which a component, in particular a cylinder liner of an internal combustion engine, which is produced for example from aluminum, is coated with an alloy, preferably with an iron alloy.
  • EP 1 967 601 A2 It is known from EP 1 967 601 A2 to coat, for example, an aluminum engine block, in particular the cylinder bearing surface thereof, with an iron alloy by carrying out arc wire spraying.
  • EP 1 967 601 A2 proposes the use of an iron alloy which contains, inter alia, 5 to 25% by weight chromium. It is essential in the case of EP 1 967 601 A2 that an additional powder, to be precise boron carbide, is additionally fed to the iron melt.
  • the arc wire spraying process of EP 1 967 601 A2 involves what is known as the TWAS process, in which two wires are fed to a spray head in such a manner that the power is transmitted across the wires.
  • an arc which melts the wires is formed by a permanent short circuit.
  • a nozzle from which compressed air or an inert gas such as nitrogen is discharged is located downstream of the nozzle. This gas stream atomizes the molten iron alloy and feeds it together with the molten boron carbide powder to the surface to be coated.
  • DE 44 11 296 A1 and DE 44 47 514 A1 are concerned with coatings provided by means of plasma spraying, in which however a metal powder or a filler wire are melted and in which nitrogen is fed to the material mixture by means of metallic nitrogen compounds in order to harden the coating.
  • Present-day internal combustion engines and the engine blocks thereof can be cast from a metal or aluminum, aluminum blocks in particular having an iron or metal layer on the cylinder bores thereof.
  • the metal layer can be sprayed on by thermal processes.
  • the processes mentioned above are known as thermal spraying processes.
  • PTWA Pulsma Transfer Wire Arc
  • bores cylinder bores
  • the plasma impinges on the preheated, wire-like spraying additive.
  • the plasma gas is usually an argon-hydrogen mixture.
  • air or compressed air is used as the transporting gas or atomizer gas.
  • the layers which are produced by this process are distinguished by a low porosity.
  • the PTWA internal coating process has proven suitable to date for the internal coating of cylinder bores.
  • the invention proposes a process for producing a coating by thermal spraying, in particular by plasma spraying, in which a component, in particular a cylinder liner of an internal combustion engine, which is produced or cast from aluminum, is coated with an alloy, in which process nitrogen is fed at least as transporting gas, a spraying additive being a solid alloy wire which is guided into a plasma stream, and coating being performed without additional powder or without powder.
  • a plasma spraying is PTWA (Plasma Transfer Wire Arc) internal coating.
  • the term “without additional powder” or “without powder” means that neither a filler wire filled with (metal) powder nor a separately fed (metal) powder is used. Specifically, in the invention, use is advantageously made merely of a solid, i.e. homogeneous or an unfilled additional spraying wire.
  • a suitable alloy for coating comprises chromium as alloying element and mainly iron. A preferred metal or iron alloy is disclosed further below.
  • ethanol-containing fuels for internal combustion engines can contain conventional fossil fuel (e.g. E5, E10 or E85) as an admixture of ethanol, or can be used in pure form (E100).
  • the additional spraying wire comprises an iron alloy with a chromium proportion of 12 to 35% by weight.
  • Further alloying constituents can be aluminum (2-10% by weight), silicon (0-1% by weight), manganese (0-1% by weight), carbon (0-1% by weight) and further constituents such as, for example, phosphorus (0-1% by weight), sulfur (0-0.09% by weight), molybdenum (0-5% by weight), nickel (0-1% by weight), copper (0-0.5% by weight), nitrogen (0-0.5% by weight), the remainder being iron.
  • the additional spraying wire comprises, according to the invention, an iron alloy comprising 23% by weight Cr, 5% by weight Al, less than 0.5% by weight Si, less than 0.2% by weight Mn, less than 0.05% by weight C, the remaining constituents having a proportion of less than 2% by weight, and the remainder being iron.
  • FIG. 1 shows a nozzle unit 1 of a PTWA internal coating apparatus.
  • the PTWA (Plasma Transferred Wire Arc) 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 perpendicularly to the plasma nozzle 3 .
  • the material used for the cathode 2 is preferably tungsten, which may also be doped with thorium, for example.
  • the plasma gas 5 for example a mixture of argon and hydrogen, is fed through bores made in the nozzle body 6 and lying tangentially to the circumference.
  • the cathode holder 7 isolates the cathode 2 from the nozzle body 6 .
  • the alloy wire 4 is guided in the wire feed 15 such that it can move in rotation and be displaced longitudinally.
  • 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 thus produced plasma flows through the plasma nozzle 3 at high speed.
  • the plasma gas 5 is transported toward the alloy wire 4 fed continuously perpendicularly to the nozzle 3 , as a result of which the electric circuit is completed.
  • a transporting gas 9 or an atomizer gas 9 is fed via feed ducts 10 and auxiliary nozzles 11 to the plasma jet 8 emerging from the pilot nozzle 3 .
  • the melting and the atomization of the alloy wire 4 are influenced in this case by two phenomena.
  • the wire 4 is firstly resistance heated by large current intensities, which are typically 65-90 amperes.
  • the impact of the plasma jet 8 on the preheated wire 4 ensures that the latter melts at the wire end 12 .
  • a plasma is generated inside the plasma nozzle 3 by means of high-voltage discharge.
  • a targeted nitrogen gas flow, i.e. the transporting gas 9 along the discharge path transports the plasma and the molten spraying material 13 onto the surface 14 of the workpiece to be coated.
