摘要:
A method electrochemically coats a substrate by brush plating. Particles are applied to the surface to be coated via a separated line system before the carrier for the electrolytes. The electrolyte is added to the carrier via a line system. The advantageous result thereof is that an agglomeration of the particles can be prevented because only a short time passes after the application of the particles until the formation of the layer. A device for electrochemical coating has two line systems for the cited purpose. The highly stressed surface components of rollers in rolling mills can be partially coated by the method.

A method for the electrochemical coating of a workpiece surface (2), micro- or nanoscale particles being introduced into the coating is provided. During coating, at least one jet composed of a jet medium comprising the micro- or nanoscale particles to be introduced is directed onto the workpiece surface (2).
摘要:
A component part has a catalyst surface. This surface has metallic components and components of MnO2 (13) in contact with the former. The metallic components are preferably formed of Ag and/or Ni. These material pairs achieve a great improvement in catalyst action compared to the pure metals. Especially in the case of use of Ni, which is toxicologically safe, these surfaces, for example, may also find use in ambient air purification for reduction of the ozone content. The surface can be applied, for example, by a coating of the component part, in which case the metallic component and the component of MnO2 are applied in two layers.

摘要:
The invention relates to a cold gas spraying method with the aid of which a substrate to be coated can be coated with particles. According to the invention, it is provided that microencapsulated agglomerates of nanoparticles are used as particles. This advantageously allows the advantages that accompany the use of nanoparticles to be used for the coating. The nanoparticles are held together by microencapsulations, wherein the microencapsulated particles formed in this way that are used in the cold gas spraying method have dimensions in the micrometer range, thereby allowing them to be used in the first place in cold gas spraying The microencapsulated nanoparticles may be used for example to produce a UV protective coating on lamp bases for gas discharge lamps.

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).
