Definitions

  • the known coating does not meet the corrosion requirements that are to be placed on an internal combustion engine. In addition, it has a tensile stress, which leads to local delamination and thus the failure of the coating in operation.
  • the coating of the invention meets all corrosion requirements that are placed on an engine block made of aluminum or the like light metal, in particular against salt and sulfur corrosion, especially in fuels with increased sulfur content, eg. B. Venezuela fuel.
  • the boron carbide is at least partially converted to iron boride (Fe x B x ) in the iron alloy molten during arc wire spraying, thereby hardening the coating and substantially increasing its wear resistance.
  • iron boride Fe x B x
  • the boron carbide is preferably used with a particle size of 0.1 to 10 microns.
  • two wires which consist of the iron alloy used in the invention, fed to a spray head, such that a current transmission to the wires, wherein the two wires touch with its end, whereby an arc is formed by a permanent short circuit, the wires melting at the end.
  • Behind the melt zone is a nozzle from which compressed air or an inert gas, such as nitrogen, exits. This gas stream atomizes the molten iron alloy and supplies it to the surface to be coated.
  • a melting head is used, which has a feed into the gas stream upstream of the arc for the boron carbide.
  • the cylinder liners of an internal combustion engine are preferably pretreated with a high-pressure water jet before coating.
  • the spray head is inserted into one of the cylinders, wherein it rotates during spraying around the cylinder longitudinal axis.
  • the applied to the cylinder bore by thermal spraying layer for example, has a layer thickness of 0.2 to 0.6 mm.
  • By honing and the like finish finally, for example, a 0.1 to 0.2 mm thick cylinder liner coating is obtained.
  • FIGURE of which shows a side view of a lance for the LDS method with a longitudinally cut extrusion head.
  • a spray head 2 is attached to a lance 1.
  • a lance 1 As shown by the arrows 3 and 4, two wires 5, 6 introduced from the iron alloy according to the invention, which are transported to the spray head 2, from which they emerge so that they touch with their ends 7, 8 , The wires 5, 6 are energized with contacts, not shown, so that forms an arc and thus a melting zone 9 at their ends 7, 8 by a short circuit.
