Definitions
- the invention relates to an aluminum plain bearing alloy with proportions of zinc, copper, magnesium, silicon and lead.
- a plain bearing alloy is, for example, AlZn, ⁇ CuMgSiPb, which the applicant has long been producing under the trade name KS 961.
- This plain bearing alloy is characterized by high resilience.
- a high quality plain bearing material has not yet been produced.
- EP 0 440 275 A1 has proposed an aluminum alloy which contains one or more of the components 1 to 50% by mass of lead, 3 to 50% by mass of bismuth and 15 to 50% by mass of indium, and additionally one or more of the components 0.1 to 20 mass% silicon, 0.1 to 20 mass% tin, 0.1 to 10 mass% zinc, 0.1 to 5 mass% magnesium, 0.1 to 5 mass% copper, Cast from 0.05 to 3% by weight of iron, 0.05 to 3% by weight of manganese, 0.05 to 3% by weight of nickel and 0.01 to 0.3% by weight of titanium, the strand is quenched by direct cooling water at 700 K / s.
- the present invention is therefore based on the object, starting from the aforementioned
- an aluminum plain bearing alloy with 3 to 6 mass% zinc, 0.3 to 2.0 mass% copper, 0.2 to 1.0 mass% magnesium, 0.3 to 2.0 mass% % Silicon and 2 to 4.5 mass% lead, which is obtainable by continuous casting with the smallest dimension, ie Thickness of the strand of more than 20 mm, when solidifying in an exclusively indirectly cooled mold, with a withdrawal speed of 1 to 5 mm / s and with a cooling rate of less than 100 K / s.
- the aluminum plain bearing alloy is preferably cast vertically.
- the cooling rate of less than 100 K / s is achieved in that the alloy or the solidifying strand is cooled not by directly quenching the strand but by applying coolant to the casting mold.
- the cooling rate during continuous casting is preferably 20 to 50 K / s.
- the withdrawal speed of the strand is preferably 1.5 to 2.5 mm / s.
- the slide bearing alloy according to the invention is advantageously characterized in that 90% of the drop-shaped lead deposits have a dimension of less than 10 ⁇ m.
- Figures 1 to 5 show micrographs of various aluminum plain bearing alloys according to the invention.
- Figure 1 shows the Schufflag an AlZn4, 5CuMgSiPbl, 9.
- the casting furnace temperature was 775 ° C, and the manifold temperature of the continuous caster was set to 745 ° C, the mold temperature to 720 ° C.
- the casting or withdrawal speed of the strand was approximately 2 mm / s.
- the result is a perfect structure that does not differ from that of the well-known aluminum plain bearing alloy KS 961.
- the casting furnace temperature was increased slightly to 780 ° C; the manifold temperature and the mold temperature remained unchanged at 745 ° C and 720 ° C, respectively.
- Figure 3 shows the micrograph of a
- Aluminum plain bearing alloy which differs from that according to FIG. 1 in that it contains 3% by mass of lead.
- the casting furnace temperature was 805 ° C, the distributor temperature 765 ° C and the mold temperature 740 ° C. The temperatures were raised because the segregation temperature in the phase gram increases with increasing lead concentration.
- Figure 4 shows the micrograph of a corresponding aluminum plain bearing alloy with 3.7 mass% lead.
- the casting furnace temperature was 815 ° C, the distributor temperature 775 ° C and the mold temperature 750 ° C.
- FIG. 5 shows the micrograph which was obtained after casting the alloy according to FIG. 4, which was alloyed with 0.2% by mass of tin and consequently contains only 3.6% by mass of lead.
- the structure contains a larger proportion of finer lead excretions than FIG. 4.
- the casting parameters corresponded to those according to the above exemplary embodiment according to FIG. 4.
