Definitions
- the invention relates to a plain bearing composite material with a hard metal support layer and a metallic slide layer which is roll-plated on the support layer and made of an aluminum alloy with 10 to 25% by mass of tin and with additions of copper and nickel, which is in direct contact with the sliding partner.
- the sliding layer therefore does not carry any further, for example galvanically applied, running layer.
- Such a plain bearing material is known for example from DE 40 04 703 AI.
- the only embodiment teaches an aluminum alloy with the composition AlSnlONi2MnlCuO, 5, wherein a lead additive can also be used instead of the tin additive.
- a "Soft phase" in the form of a tin or lead excretion is required to ensure good emergency running properties of a bearing made from the plain bearing material. Hard dirt particles or abrasion are absorbed or embedded in this soft phase.
- the soft phase can also adapt to geometric conditions.
- the soft phase made of tin, which is not soluble in aluminum, is absorbed in the form of block-like precipitates in the matrix-forming aluminum.
- the object of the present invention is to improve an alloy of the type described in the introduction in such a way that it has a higher load capacity than the known aluminum-tin-copper or aluminum-tin-copper-nickel alloy and has better formability, in particular plating properties.
- a slide bearing composite material of the type described in the introduction which is characterized in that the aluminum alloy of the sliding layer consists of tin, copper, nickel and the rest of aluminum, and that copper and nickel each have a share of 0.2 to 2% by mass and the ratio of the mass percentage of copper to the mass percentage of nickel is between 0.6 and 1.5.
- the aluminum alloy according to the invention can have additives due to contamination as a technical alloy.
- Contamination elements understood up to a maximum of 0.2 mass% per element. In total, contamination-related additives can contain up to about 1% by mass without departing from the scope of the invention.
- nickel forms a stationary and, unlike copper-containing intermetallic aluminide phases such as Al 2 Cu, a glow-stable intermetallic phase that acts as a copper sink to a certain extent. This prevents the copper from migrating within the matrix in the course of the heat treatment and leads to a coarsening of the precipitation phases (one speaks here of Ostwald ripening). Such coarsening is undesirable because the coarse precipitations represent potential fatigue or crack formation points within the alloy, which deteriorate the formability and in turn reduce the load capacity. Due to the relatively high solubility of the copper in the aluminum mixed crystal, Al 2 Cu precipitates tend to coarsen.
- the alloy AlSnl2CulNi according to the invention high Matrix hardness and very good deformability achieved.
- the alloy material is easy to roll even with large stitch decreases of more than 50%. This is attributed to the interaction of copper and nickel.
- High matrix contents of copper lead to a high matrix hardness (mixed crystal hardening).
- B. Al 2 Cu which have a negative impact on the formability and fatigue strength.
- the addition of nickel prevents or at least significantly reduces the formation of coarse aluminum-copper phases, since nickel-copper-aluminide is preferably formed, which is hardly prone to coarsening.
- the nickel-copper aluminides are finely divided even after heat treatment at 250 degrees. The reason for this is the extremely low solubility of nickel in the aluminum mixed crystal.
- the essential effect of the claimed nickel content depending on the copper content is to bind copper in the form of nickel-copper aluminide and thereby suppress or reduce the formation of Al 2 Cu precipitates.
- These Al 2 Cu precipitates have a particularly detrimental effect on the formability because, in contrast to the thermally stable nickel-copper aluminides, they coarsen during the heat treatment and thus represent potential starting points for cracks.
