Definitions

  • the invention relates to a wettable powder with aluminum oxide and titanium dioxide for the production of wear-resistant and high-temperature resistant coatings on in particular the running and friction surfaces of internal combustion engines.
  • Machine parts exposed to sliding friction and / or high-temperature stresses such as piston rings, the piston crowns or the top land of pistons, and the friction surfaces of synchronizer rings, preferably by means of a plasma spraying process.
  • the present invention is therefore based on the object to further improve thermal spray coatings with aluminum oxide and titanium dioxide, in particular with regard to their wear resistance, their fire resistance, their thermal shock resistance and, in connection with this, their outbreak resistance or their compatibility with the counterpart.
  • the thermal spray coatings should be as simple and cost-effective as possible to produce and rework, and they should not only be used for coatings on piston rings in chambered or overmolded form but also for coatings on similarly loaded machine parts in internal combustion engines Piston bottoms or the top land of the pistons or on the friction surfaces of synchronizer rings.
  • this object is achieved by a wettable powder composed of 50 to 90 percent by weight aluminum oxide and 5 to 40 percent by weight titanium dioxide, the total of 5 to 30 percent by weight lanthanum oxide (La 2 0 3 ) and / or niobium oxide (Nb 2 0 5 ), optionally with a content of up to 30 weight percent calcium carbonate are added. It was found that if only lanthanum oxide is used as an additive, this can also be used alone without additions of calcium carbonate. According to the invention, the lanthanum oxide does not necessarily have to be present as pure lanthanum oxide, but can also contain up to about 30 percent by weight of other oxides of the rare earth metals in the mixture.
  • niobium oxide when using niobium oxide as an additive, however, it preferably contains up to a maximum of 30 percent by weight calcium carbonate.
  • the coatings are preferably produced by a plasma spraying process with primary and secondary gases, preferably of nitrogen and hydrogen, argon and hydrogen or else nitrogen and argon.
  • the spray layers can be applied to the machine parts, preferably made of cast iron, steel or aluminum or aluminum alloys, directly or using previously applied intermediate layers, usually made of molybdenum, nickel-chromium alloys or nickel-aluminum alloys.
  • the layers can either be overmoulded over the entire surface or injected as fillings into one-sided or two-sided chambered depressions.
  • the wettable powders are preferred for the coating of piston rings and for the full or partial coating of the piston crowns and / or the top land areas of pistons. used in internal combustion engines. However, the powders are also suitable for producing a wear-resistant coating on the friction surfaces of other machine parts, such as, in particular, synchronizer rings.
  • piston rings with various powder compositions, according to the invention produced in overmolded form and in one or both sides chambered form with and without the use of intermediate layers. After test runs with simulated extreme loads, the layers showed only slight wear and tear, no burn marks and no signs of breakouts. The cylinder surfaces examined as counter-rotating partners showed no major signs of wear.
  • the known wettable powder made of aluminum oxide and titanium dioxide is improved so much, especially with regard to its thermal shock resistance and its resistance to breakout, that it can be used to produce coatings on machine parts subjected to friction with the relatively high thermal load of an internal combustion engine.
  • the significantly improved breakout resistance of the layers seems to be caused by two different mechanisms of action. It was found that with a proportion of only 5 to 10 percent by weight addition of lanthanum oxide and / or niobium oxide with calcium carbonate, above all, it only improves the internal cohesion of the layers.
  • the layers additionally showed a multiplicity of microscopic cracks which, when subjected to stress, lead to a partial or complete reduction of internal tensions in the layers and thus the breaking out of the layer or parts of it Prevent layer effectively.
  • the invention thus provides wettable powders based on aluminum oxide and titanium dioxide, which can be used to produce wear-resistant and fire-retardant and at the same time heat-resistant and thermo-shock-resistant and therefore break-out-resistant coatings on, above all, thermally stressed machine parts in internal combustion engines by means of plasma spraying processes.
  • the spray powders used are inexpensive primarily because of the aluminum oxides and titanium dioxides used, and the layers produced can be reworked relatively easily after spraying.
  • the intermediate layers used preferably consist of a nickel-chromium alloy with 80 percent by weight of nickel and 20 percent by weight of chromium and a nickel-aluminum alloy with 95 percent by weight of nickel and 5 percent by weight of aluminum.
