    • The invention relates to a component that is suitable for use as a sliding bearing. The invention further relates to a method for the production of said component. The design of the component according to the invention provides a layer of a light metal material (13), which is provided with an oxide layer (15) containing pores (16) in the direction of the sliding surface (23) of the component. A hard material (18) is placed in the pores, which greatly increases the firmness of said layer region, thus creating the mechanical firmness for use as a sliding bearing. In order to counteract the tendency of said firm layer region to experience brittle failure, the oxide layer (15) is coated with a solid lubricant layer (20). Said solid lubricant layer comprises a metallic, ductile matrix (21), which distributes a force (F) acting at certain points over a larger surface region (b). In order to improve the sliding characteristics, particles of a solid lubricant (22) are simultaneously embedded in the solid lubricant layer (20).
    • 本发明涉及适用于滑动轴承的部件。 本发明还涉及生产所述组分的方法。 根据本发明的部件的设计提供了一种轻金属材料层(13),其在该部件的滑动表面(23)的方向上设置有包含孔(16)的氧化物层(15)。 一个硬质材料(18)被放置在孔中,这大大增加了所述层区域的硬度,从而产生用作滑动轴承的机械硬度。 为了抵消所述牢固层区域经历脆性破坏的倾向,氧化物层(15)涂覆有固体润滑剂层(20)。 所述固体润滑剂层包括金属的延性基体(21),其分配在较大表面区域(b)上的某些点处作用的力(F)。 为了提高滑动特性,固体润滑剂(22)的颗粒同时嵌入固体润滑剂层(20)中。

    • The invention relates to a surface comprising a microstructure that reduces adhesion and to a method for producing said microstructure. Microstructures of this type that reduce adhesion are known and are used, for example, to configure self-cleaning surfaces that us the Lotus effect. According to the invention, the surface is produced electrochemically by means of reverse pulse plating, the known microstructure being first produced and a nanostructure that is overlaid on the microstructure is produced at the same time or in a subsequent step. To achieve this for example, the pulse length of the current pulse that is used during the reverse pulse plating lies in the millisecond range and has a pulse length ratio greater than 1:3. The microstructure that has been produced, consisting of peaks and troughs is then overlaid with peaks and troughs of a smaller size order belonging to the nanostructure.
    • 本发明涉及一种包含减少粘合性的微观结构的表面和一种用于生产所述微结构的方法。 这种减少粘附性的微结构是已知的,并且用于例如配置我们莲花效应的自清洁表面。 根据本发明,通过反向脉冲电镀电化学地制造表面,首先制造已知的微结构,并且在同一时间或后续步骤中产生覆盖在微观结构上的纳米结构。 为了实现这一点,例如,在反向脉冲电镀期间使用的电流脉冲的脉冲长度在毫秒范围内,并且具有大于1:3的脉冲长度比。 由峰和谷组成的已经产生的微结构然后用属于纳米结构的较小尺寸的峰和谷覆盖。
