Traditionally, adhesive underlayers of aluminum and aluminum alloys coated on a steel substrate have been used for various maintenance-free laminated plain bearings.
This sublayer is intended to provide a strong connection between the carrier material and the applied sliding layer. The coating of aluminum adhesive underlayers on steel substrates is carried out with various techniques according to the current state of the art. In other words, for laminated plain bearings, the adhesive lower layer is sintered in powder form (DE-AS1, 286, 827), and the surface structure is hot rolled (DE-OS3, 017, 544).
Alternatively, a spray method (DE-OS2, 928, 572) is known. Adhesive underlayers coated in this way generally guarantee the desired strong connection between the substrate and the sliding layer, but the equipment costs are high and, moreover, these techniques require high energy requirements. do. Also from DD-PS61393, a pretreated carrier steel plate is coated with a particularly resin-based adhesive, a powdered or granular sliding layer mixture is laminated directly onto this adhesive layer, and then these The layers are fixed by applying alternating pressure and temperature. Although this technique provides a sufficiently strong layer connection for many applications without the use of a metal adhesive underlayer, it has limitations in use, primarily due to the high degree of endpressure that is often implemented. This end pressure can lead to local delamination of the layer upon application of thicker sliding layers.

The porous aluminum layer exhibiting ~40% porosity is
It gives the sliding layer very good anchoring properties, and the frictional heat generated during operation can be effectively dissipated to the substrate.Also, as a result of the light rolling of the aluminum particles, many particles penetrate the adhesive layer. This leads to direct contact with the substrate. At the same time,
Aluminum powder has proven to be particularly suitable as an adhesive medium because, unlike other metal layers, it is inherently cohesive.

施する。 For example, a 1.5 mm thick steel plate is degreased in a pickling solution, and then one side of the surface is roughened by chemical treatment. Next, on this pretreated substrate,
An adhesive in the form of a phenol-formaldehyde condensation product with a drying content of 0.4-0.5 g/dm 2 is applied. Adhesives of this type are known, for example, under the trademark "Plastotherm 2355". after that,
Aluminum powder, preferably with a particle size of 10 to 20 .mu.m, is spread in a suitable device to a thickness of 200 to 300 .mu.m and rolled under light pressure. While the aluminum powder coating is not bonded to the adhesive, any loose particles are removed by tilting the substrate. This is followed by a heat treatment at a temperature of 145° C. for 30 minutes to harden the formaldehyde condensation product. Then, as the case may be, particles that are still loosely attached or that are not fixed are removed with a brush. A sliding layer is laminated onto this aluminum layer as adhesive medium. This slip layer is made of, for example, 37% by weight of crystalline PTFE,
It is a homogeneous slip material mixture consisting of 50% by weight lead powder and 13% by weight phenolic resin. This sliding layer can likewise be applied in a dry state, but it can also be formed in the form of a paste, and has a thickness of 1.5 to 2.5 μm depending on the application of the sliding bearing. Following this coating, a heat treatment for 60 minutes at approximately 85° C. is first carried out for precondensation of the phenolic resin. Subsequently, adhesion is performed for 25 seconds under a pressure of 20 to 40 MPa, then pressureless heat treatment is performed at 145° C., and finally final adhesion is performed for 25 seconds at 20 to 40 MPa.

Such bearing surfaces exhibit particularly good sliding properties during maintenance-free operation and are most suitable for high specific surface loads.
