Definitions

  • the invention relates to a coating on a cylinder running surface a reciprocating piston machine based on iron, aluminum or magnesium with a hypereutectic aluminum / silicon alloy and / or an aluminum-silicon composite material as well a method of making this coating, like both is used in industry.
  • the inside of the liner is roughly turned, honed and exposed.
  • This solution is with constructive, manufacturing and not least economic Disadvantages such as limited adhesion of the AlSi10 melt to the Bushing surface, complex handling and high price combined.
  • the bushing wall thickness affects the minimum Cylinder spacing.
  • the web width should, especially at future small size engines should be as small as possible because it determines the minimum outer dimensions of the engine.
  • Thermal spraying offers other wear-resistant options Coatings on the cylinder wall of the crankcase to apply.
  • the basic principle of thermal Spraying is that a meltable or partially meltable Material in a high speed hot gas jet small droplets melted and towards the coated surface is accelerated (DIN 32530). When bouncing the spray droplets solidify on the relatively cold one Metal surface and form layer by layer Layer.
  • Advantage of this coating technology over the Electrodeposition, chemical or physical vapor deposition is the high order rate that allow one Coating the cylinder bore economically in a few minutes.
  • the methods of thermal spraying differ according to the type of production and the properties of the high-speed hot gas jet.
  • the object of the invention is to provide a coating for cylinder running surfaces to develop the coating in high quality can be manufactured easily and cheaply. Furthermore it is an object of the invention to provide methods with which appropriate coatings can be applied.
  • the invention allows after the actual die casting process the cylinder tread of a die-cast engine block, the preferably based on iron or light metals - especially aluminum and magnesium - based on a thermal Spraying process directly with a wear-resistant coating are coated from aluminum and silicon, which makes the previously usual and complex liner solution is replaced.
  • a Another advantage is that the thickness of the actual, tribological Running layer on the tribologically non-executable, but well castable and machinable crankcase considerably is reduced. At 0.1 to 0.2 mm it is less than 1/10 of the usual can wall thickness and therefore offers the Possibility to build much more compact motors.
  • the coating according to the invention without changing the manufacturing facilities installed today to integrate into the series, making the costly Manufacturing and handling of the cylinder liners are eliminated and significant amounts of material can be saved. Therefore must apply the coating at high application rates take place in particularly short cycle times.
  • the coating can also fit the shape very precisely Cylinder barrel wall of the crankcase applied and a fine surface quality can be set, making complex Post-processing steps such as pre-turning and fine turning are no longer necessary and thus significantly reduce manufacturing costs.
  • the use of special aluminum / silicon wettable powders for the production of the coating in the atmospheric, thermal spray process creates a heterogeneous layer structure of aluminum mixed crystal, silicon precipitates or particles, intermetallic phases such as Al 2 Cu and Mg 2 during the layer-like layer formation Si and extremely finely divided oxides, the formation and distribution of the oxides being due exclusively to the non-equilibrium properties of the atmospheric, thermal spray processes. Due to the finely distributed oxides, the coating has exceptionally good wear resistance.
  • Figure 1 is a micrograph of the spherical spray particles made of alloy A, from which the aluminum mixed crystal structure and the Si primary separations clearly are evident.
  • FIG 2 is a scanning electron microscope image plasma-sprayed layer depicted with the wettable powder alloy A was produced. The cut was etched to attack the aluminum mixed crystal and thus the structure to clarify.
  • the structure consists of primary aluminum mixed crystal dendrites, where the dendrite arms of eutectic silicon are enveloped. The size of the dendrite arms fluctuates a lot, so that they can only be partially dissolved.
  • the fluctuations in the subtlety of the structure at hand comes from the fluctuations in temperature and speed of individual Melt drops and on the other hand from the different nucleation in the solidification of various melting drops.
  • a Such a fine structure characterizes thermally sprayed layers towards the microstructures that are over powder metallic Routes are obtained and is for good wear resistance of those layers responsible.
  • the agglomerated Composite powders consist of fine silicon particles and fine, metallic particles of an aluminum-silicon alloy, the one another on the basis of inorganic or organic Binders are bound, the proportion of silicon particles 5 to 50% and the proportion of alloy particles 50 is up to 95%.
  • the silicon particles have a medium one Grain size of 0.1 to 10.0 microns, preferably about 5 microns.
  • the metallic Particles have an average particle size of 0.1 up to 50.0 ⁇ m, preferably about 5 ⁇ m and alternatively consist of both usable hypoeutectic alloys C or D, or from both alternative hypereutical alloys that can be used E or F.
  • hypereutectic Alloy particles are the proportion of aluminum mixed crystal maintained in the layer structure during the formation of the aluminum mixed crystal in the layer structure through the use of hypoeutectic Aluminum / silicon particles is suppressed.
  • the coating of a cylinder running surface or -drilling assumes that the casting of the light metal block is on the usual way in the die casting process, but without the cylinder liners inserted into the mold.
  • the inside of the Cylinder barrel bore of the crankcase is then done in one operation roughly turned to the required shape and position tolerances to ensure.
  • the aluminum silicon Layer applied.
  • the coating process can either be done in the form that in the hole a suitable, commercially available one around the central axis of the cylinder bore rotating internal burner introduced and is moved axially, or a non-rotating burner in the cylinder bore of the rotating crankcase introduced and is guided along the central axis of the cylinder bore the layer at almost a right angle to the cylinder barrel wall spray on.
  • the latter is procedurally simpler and safer because the supply of the necessary media such as electrical Energy, cooling water, primary and secondary gas and Spray powder from a rotating aggregate is problematic.
