Definitions

  • the invention relates to the running surfaces of piston machines consisting of pistons and cylinders, in particular air compressors, according to the preamble of claim 1.
  • the cylinders which usually consist of eutectic or hypereutectic aluminum alloys, are separated from the pistons, which are usually made of a eutectic aluminum alloy, and are made in mold or die-casting by coating a running surface.
  • the friction partner piston which is made of mold aluminum, for example, in order to achieve a separation of the base materials. This separation is achieved through the use of iron, chromium, nickel layers or through the use of so-called lubricating varnishes with MOS 2 or graphite components.
  • the invention has for its object a tread of the type mentioned and a method for producing such a tread. to create, which meet the highest demands in terms of wear resistance and heat resistance at high running speeds and high loads.
  • the oxide ceramic material bound in synthetic resin varnish which preferably contains aluminum oxide (Al 2 0 3 ) and sintered zirconoid (Zr0 3 ), results in high wear resistance, whereby the combination of these two materials results in an elasticity that ensures that foreign bodies can be embedded.
  • the coating also provides an ideal base for the wetting lubricants.
  • the size of the wear resistance can be influenced by using different amounts of solids.
  • the coating is carried out by application using a pressurized spray device. Since only one of the two friction partners is coated, the piston is ideal because of the lower workload.
  • the piston is about an hour in a drying oven at a temperature of about 200 ° C, in particular dried from 220 ° C, a chemical transformation process causing the desired property of the surface. Subsequent processing of the surface is not necessary.
