    • The invention relates to a cylinder liner, cast into a reciprocating piston engine, of a highly hypereutectic aluminum/silicon alloy which is free of hard material particles independent of the melt and has such a composition that fine primary silicon crystals and intermetallic phases automatically form from the melt as hard particles. By spray-compacting, a blank of finely sprayed melt droplets is caused to grow, a fine distribution of the hard particles being produced by controlled introduction of small melt droplets. The blank can be transformed by an extrusion step into a form approximating the cylinder liner. After subsequent premachining with chip removal, the running surface is precision-machined and subsequently honed in at least one stage, after which the hard particles located in the running surface are exposed, plateau faces of the particles being formed, which faces protrude from the remaining surface of the matrix structure of the alloy. The exposing of the primary crystals and/or particles is effected chemically, using aqueous alkali. Owing to the fine-grained hard particles formed in the melt and to their large proportion in the matrix structure and owing to the exposing of the hard particles in the matrix structure, not only high wear resistance and a high load bearing proportion of the running surface result, but also the possibility of using inexpensive piston ring fittings and piston coatings with, at the same time, low oil consumption and correspondingly low hydrocarbon emissions.
    • 本发明涉及一种铸造成往复式活塞发动机的气缸套,其具有高度过共晶的铝/硅合金,其不含与熔体无关的硬质材料颗粒,并且具有这样的组成,即从初始硅晶体和金属间相 熔体作为硬粒子。 通过喷雾压实,使细微喷雾熔融液滴的空白生长,通过控制引入小熔体液滴产生的硬颗粒的精细分布。 坯料可以通过挤压步骤转化成接近气缸套的形式。 在随后进行切屑去除之后,运行表面被精密加工并随后在至少一个阶段中珩磨,之后暴露位于运行表面中的硬质颗粒,形成的颗粒的平台面朝向从其余部分突出 合金基体结构的表面。 使用碱水溶液化学地进行初晶和/或颗粒的暴露。 由于在熔体中形成的细粒硬颗粒和其在基体结构中的较大比例,并且由于硬颗粒暴露在基质结构中,不仅高耐磨性和高承载比的流动表面 结果,而且也是使用廉价的活塞环配件和活塞涂层的可能性,同时具有低的油耗和相应地低的碳氢化合物排放。

    • A dishwasher having a washing compartment for items to be washed and a first circulation circuit to subject the items to a washing liquid. The first circulation circuit includes a circulation pump; a water heater; and a spraying device. The washing liquid is routed from the washing compartment to the pump and fed back into the washing compartment. A second circulation circuit has the circulation pump, the water heater and a mixture store with input and output openings. An output side of the pump has a branching point that flow controllers are assigned to to allow the washing liquid to circulate in the first circulation circuit and/or the second circulation circuit. In the second circulation circuit, the washing liquid is routed from the washing compartment to the pump, pumped into the mixture store via the input opening, and fed back into the washing compartment via the output opening.
