Definitions

  • the invention relates to a cylinder liner for internal combustion engines for use in the cylinder bores of an engine block, the cylinder liner being produced in a free-form process by thermal spraying of spray material onto a mandrel serving as a shaped body to form a cylinder wall, and the process for its production.
  • cylinder liners In internal combustion engines with an engine block made of cast iron or aluminum alloys, it is common practice to insert cylinder liners into the cylinder bores of the engine block.
  • the bushings consist of cylindrical tube sections and limit the combustion chamber of the combustion chamber with their inner surfaces in the engine, the inner surfaces simultaneously serving as running surfaces for the piston rings.
  • wear-resistant cast iron or steel alloys or sintered materials are used as the liner materials.
  • the running surfaces of the bushings must also be machined, and if necessary the running surfaces are provided with wear-resistant coatings.
  • cylinder liners can only be manufactured within a limited range of dimensions using the casting and sintering processes.
  • thin-walled cylinder liners which are required above all for modern car engines with engine blocks made of aluminum alloys to optimize performance, cannot be produced using the previous processes, or can be produced only with great effort.
  • US 5110631 A discloses a method for coating bodies by spraying on spray materials.
  • the spray material is sprayed onto the body in a special spraying technique and is used to produce separate bodies or as a coating.
  • the coating structure is one layer.
  • the present invention has for its object to provide a cylinder liner for internal combustion engines and a method of their manufacture, with which a cylinder liner can be manufactured easily and inexpensively with optimally thin walls and high wear resistance and can then be used as an independent component in an engine block ..
  • a dome with an outer circumference corresponding to the inner circumference of the cylinder liner to be produced is used as the molded body, and the spray material is applied in the desired thickness to the outer circumferential surface of the rotating mandrel by one of the known thermal spray processes. After removal from the mandrel, the bushing is machined on the end faces.
  • the completed cylinder liner according to the invention is stable and can be easily stored and handled from manufacture to installation in the engine block.
  • cylinder liners with standard diameters can be produced for all common engine types.
  • the socket can be manufactured primarily with thin walls with wall thicknesses of greater than or equal to 1 mm and in lengths from 100 mm to 260 mm. Other dimensions would also be conceivable.
  • the layer forming the tread consists of a particularly wear-resistant and fire-retardant material made of molybdenum or a molybdenum alloy, while the outer cover layer can consist of an aluminum alloy.
  • a bonding layer made of, for example, a self-flowing cobalt or nickel alloy can be applied in between. It is particularly advantageous here that the choice of material can be matched to the application and, above all, that a tread layer with optimal tribological properties can be produced by adjusting the spraying parameters.
  • the outer circumferential surface of the molded body is hard chrome-plated and optionally provided with a non-stick spray, so that the finished bushing can be easily removed from the molded body.
  • a special and complex machining of the tread of the bush is not necessary in most cases, since the tread has a shape corresponding to the surface of the molded body.
  • the cylinder liners according to the invention were tested in engine tests.
  • the cylinder liner was also optimally wear-resistant in endurance tests and ran trouble-free.
  • the invention thus creates a cylinder liner that can be produced simply and inexpensively by the method according to the invention.
  • the liner according to the invention can be manufactured with optimal wear resistance values and tribological properties.
  • the cylinder liner with thin-walled geometry can be manufactured for practically all engine types.
  • the invention is illustrated in the drawing using an exemplary embodiment.
  • the cylinder liner (1) is formed from three superimposed thermal spray layers.
  • the inner layer (2) of the cylinder liner consists of a wear-resistant and fire-proof molybdenum layer. It forms the running surface for the piston rings and limits the combustion chamber of the combustion chamber.
  • a low-melting cobalt alloy is applied as an intermediate adhesive layer (3) to the outer peripheral surface of the molybdenum layer (2), and the outer layer (4) of the cylinder liner (1) consists of an aluminum alloy as a cover layer.
  • the transitions between the individual layers (2, 3, 4) can be carried out in a graded manner.
