Definitions

  • the invention relates to a method for repairing worn sliding surfaces, in particular for cylinder surfaces of engine blocks, according to the preamble of Claim 1.
  • an iron-containing layer on the sliding surface is, wherein the iron-containing layer has an amorphous structure with finely divided, nano-crystalline Metal borides and / or metal carbides may have a sliding surface be produced with high strength.
  • spraying remain the obtained original dimensions of the sliding layer, there are z. B. in the overhaul of Internal combustion engines no pistons with oversize necessary. Furthermore, the iron-containing layer used by their amorphous structure very cheap Sliding friction properties on.
  • the iron-containing layer has an excellent mechanical connection or Clamming to the base material due to the amorphous solidification and is thus being able to be applied to the sliding surface machined by ablation become.
  • the removal of the Sliding surface before the application of the layer may be by any suitable Surface treatment methods take place, for. B. drilling, turning, milling, Grinding or sanding, sandblasting, lasers. This allows flexible use the layer in any repair work on sliding surfaces. Because of the high Hardness and firmness of the layer will also be a possible weakening of the Base material compensated by wear or subsequent removal, so that the original strength of the base material can be almost achieved again can.
  • Application example is the critical web area between cylinder bores an engine block.
  • the coating is particularly suitable for thermal shock stressed engines. Thermal shock occurs when at cold start at low Ambient temperatures Engines quickly under load to maximum speed to turn up.
  • the iron-containing layer having an amorphous structure with has finely divided, nano-crystalline metal borides and / or metal carbides is the sliding surface highly resilient, because of the nano-crystalline precipitates the metal boride and metal carbides create a layer of extremely high hardness.
  • iron-containing layer is repair highly loaded cylinder surfaces of supercharged diesel and gasoline engines.
  • inventive layer in the drilled cylinder bore the cylinder bore is brought back to the original nominal size, so that the original piston can be used.
  • the layer is a very high strength, including the original strength of the engine block even restored, since the engine block is now the original Has wall thicknesses.
  • the coated iron-containing layer is subsequently with points with Heat applied, z. B. by laser light and / or electron beams. Then In the area of the heat input, finely divided nanocrystalline metal borides are formed and / or metal carbides from the amorphous structure of the iron-containing layer excreted.
  • the iron-containing layer when applying a relative have high content of crystalline and / or partially crystalline structure. This allows the favorable mechanical processing.
  • the iron-containing layer preferably has a hardness in the region of the heat input from 1000 to 1250 HV 0.05 on, however, the hardness can be adjusted by appropriate Process parameters and material composition readily in the range be set between 800 HV 0.05 and 1500 HV 0.05. Such hardness is previously z.
  • tungsten carbide / cobalt based tungsten carbide tools known, and can now be applied over a large area for sliding surfaces. Due to the high hardness, the iron-containing layer is extremely wear-resistant.
  • the Metallboride or metal carbides preferably have a size of 60 to 130 nm on. Due to the small size, the friction is reduced and the hardness increased.
  • the thermal spraying method is for application the iron-containing layer a plasma wire spraying (PTWA) or a Arc wire spraying (LDS). Both methods allow for more correct Setting the process parameters a cost-effective application of ferrous Layer.
  • PTWA plasma wire spraying
  • LDS Arc wire spraying
