Definitions

  • the invention relates to a formed according to the preamble of claim 1 surface layer for forming a tread on a cylinder wall, a defined in the preamble of claim 6 spray powder for producing the surface layer and a circumscribed in the preamble of claim 11 method for producing such surface layers.
  • machinability of such plasma spray coatings can be significantly increased by adding solid lubricants, for example by adding hexagonal boron nitride BN, MoS 2 or WS 2 .
  • solid lubricants for example by adding hexagonal boron nitride BN, MoS 2 or WS 2 .
  • Boron nitride and the abovementioned sulfides are difficult to incorporate into the layers because they react with the oxygen in the air or are decomposed by the high temperature of the plasma. They have to be protected by expensive cladding.
  • Insert sleeves for cylinder surfaces known, which consist of supereutectic aluminum / silicon alloys.
  • the insert bushing is subjected to mechanical machining after insertion into the engine block, by first rough and then finely working its surface. In a final processing phase, the surface is honed. After honing are those particles that are harder than the microstructure of the base alloy, namely Silicone crystals and intermetallic phases, slightly above the actual surface. These exposed particles should improve the wear resistance.
  • the object of the invention is to propose a surface layer for forming a tread on a cylinder wall according to the preamble of claim 1, which can be easily applied to the cylinder wall and significantly better machinable without the other important functions of the coating material be negatively influenced.
  • the wear resistance and the low coefficient of friction should be maintained or even improved with respect to the piston ring materials coming into contact with the surface layer.
  • the separate phases of constituent surface layer for forming a tread on a cylinder wall by plasma spraying of an iron-containing spray powder is generated, which contains all components of the surface layer to be generated.
  • the surface layer can either be applied directly to the cylinder wall or to an insert bush, which is used to form the running surface in the cylinder bore.
  • preferred additives are chromium, manganese, sulfur and carbon. Suitable are e.g. but also bismuth, lead, tellurium and selenium. The substances mentioned can be added in elemental form or in the form of compounds.
  • the sprayed coatings produced have the same composition as the spray powders used.
  • claim 6 is also a spray powder for the production of surface layers according to claim 1 and in claim 11, a method for the production of surface layers proposed according to claim 1.
  • Preferred compositions of the molding powder are defined in claims 7 to 10 while a preferred embodiment of the method of producing the surface layers is defined in claim 18.
  • the wettable powders advantageously have a particle size of from 5 to 60 .mu.m, preferably from 10 to 45 .mu.m.
  • the layers thus produced are corrosion resistant to sulfuric and formic acids, i. Condensates that can form in internal combustion engines.
  • the proposed surface layers and the proposed powders are particularly suitable for direct application to the cylinder wall of engine blocks, in particular engine blocks made of light metal.
  • the spray powder is preferably applied by means of a plasma spraying device with a rotating plasmatron.
