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, in particular on the running and friction surfaces of friction sliding in internal combustion engines and / or high-temperature loads exposed to machine parts, such as piston rings, the piston crowns or the top land of pistons, and the friction surfaces of synchronizer rings , preferably by 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 manufacture and rework, and they should not only cover coatings on piston rings in a chambered or overmolded form, but also coatings on similarly loaded machine parts in internal combustion engines, such as on piston crowns or the piston top land 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 (Al 2 O 3 ), 5 to 40 percent by weight titanium dioxide (Ti0 2 ) and 5 to 30 percent by weight lanthanum oxide (La 2 0 3 ) and / or niobium oxide (Nb 2 0 5 ) dissolved, with the latter ingredient optionally being added up to 30 weight percent calcium carbonate.
- Al 2 O 3 aluminum oxide
- Ti0 2 titanium dioxide
- La 2 0 3 lanthanum oxide
- Nb 2 0 5 niobium oxide
- the lanthanum oxide does not necessarily have to be present as pure lanthanum oxide, but can also contain other oxides of the rare earth metals up to about 30 percent by weight 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 wettable powder is preferably used in the form of mixtures of the individual components with one another.
- at least two of the components thereof can also be in the form of composite powders or as micropellets pressed together, or at least two of the components can be used in the form of compounds with one another.
- the grain sizes of the powders used are preferably between 5 and 106 ⁇ m.
- the coatings are preferably produced by a plasma spraying process using 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 made of preferably cast iron, steel or aluminum or aluminum alloys directly or using previously applied intermediate layers made of mostly molybdenum, nickel-chromium alloys or L nickel-aluminum alloys.
- the layers can be either over the entire area over molded or injected as fillings in one or two sides' chambered wells.
- the wettable powders are preferred for the coating of piston rings and for the entire or partial surface coating of the piston crowns and / or the top land areas used by pistons in internal combustion engines.
- 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 in overmolded form and in one- or both-sided chambered form were produced 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 outbreaks. 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 so significantly improved, particularly with regard to its thermal shock resistance or its breakout resistance, that it can be used for the production of coatings machine parts subject 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.
- 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 thus break-out-resistant coatings on, above all, thermally stressed machine parts in internal combustion engines by means of plasma spraying processes.
- the wettable powders used are mainly 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.
