Abstract: The present disclosure relates to a sliding bearing comprising a first bearing element and a second bearing element. The first bearing element is coated in multiple layers. An inner layer is deposited on a base material of the first bearing element by means of a vapor deposition method. The inner layer has a structure, and an outer layer designed as a PTFE impregnation layer leveling the structure of the inner layer. The second bearing element is formed of PTFE fiber-reinforced plastic or has a PTFE-containing sliding lining.

Abstract: A heatable treatment container for receiving a treatment bath for treating a surface of at least one large-format component having a diameter or dimensions in the range of 0.5 m to 12 m includes a container base with a container bottom, a container wall adjoining the container base, a removable lid, and a central heating column. The central heating column extends from the container bottom towards the removable lid or from the removable lid towards the container bottom. In an example embodiment, the central heating column extends from the container bottom over at least 50% of a height of the container wall towards the removable lid. In another example embodiment, the central heating column extends from the removable lid over at least 50% of a height of the container wall towards the container bottom.

Abstract: A process for surface modification of a component includes providing a first reactor for a main procedure and a second reactor for an ancillary procedure. The first reactor is charged with a main medium, a component is provided to the first reactor, and the main procedure is performed by bathing the component in the main medium to bring about a chemical change onto a surface of the component. The second reactor is charged with an ancillary medium, the component is provided to the second reactor, and the ancillary procedure is performed by bathing the component in the ancillary medium to treat the surface of the component. The chemical change is a surface modification that takes the form of bluing or phosphatizing, the surface modification forms a conversion coating, and the component has a diameter or dimensions in the range from 0.5 m to 12 m.
