The invention relates to a multilayered bearing shell () comprising a back metal layer () as a carrier element for the layer structure and at least one further bearing layer joined to the back metal layer (), wherein the back metal layer () is made from a bronze. The back metal layer () contains in addition to copper, which forms the matrix of the bronze, tin in a proportion selected from a range with a lower limit of 1.25 wt. % and an upper limit of 12 wt. %, zinc in a proportion selected from a range with a lower limit of 0.25 wt. % and an upper limit of 6 wt. % and phosphorus in a proportion selected from a range with a lower limit of 0.01 wt. % and an upper limit of 0.5 wt. %.

Multilayered bearing shell

The invention documents an anti-friction lacquer containing at least one additive () that has a polymer matrix distributed within. Additive () is subject to change in temperature conditions in a temperature region with an upper threshold of 600&#xb0; C. for a particular irreversible energy consuming conversion, such as phase change or modification change.

Anti-friction lacquer

The invention relates to an aluminium alloy used as a coating for surfaces subjected to extreme friction stress, with an aluminium matrix incorporating at least a soft phase and a hard phase, as well as a process for producing the coating. The soft phase and/or the hard phase is essentially finely distributed in the aluminium matrix () and at least 80%, preferably at least 90%, of the soft phase or soft phase particles () have a mean diameter of a maximum of 3 &#x3bc;m. The aluminium alloy is produced by depositing it on the base () by a process of deposition from a gas phase.

Aluminum alloy for surfaces which are subjected to extreme stresses due to friction

A method is described for producing a stratified composite material, with a melt of a layer material being cast progressively in a forward feed direction onto a strip-like metal carrier which is heated to a treatment temperature required for the bonding with the layer material and is cooled below the melting temperature after the casting via the metal carrier. In order to provide advantageous casting conditions it is proposed that the metal carrier is heated continuously with a temperature profile prior to the casting of the melt of the layer material in the forward feed direction, which temperature profile decreases towards lower temperatures from a maximum temperature below the treatment temperature in the region of a surface layer receiving the melt towards a core layer of the metal carrier, and that the metal carrier is heated in a surface layer by the melt to the treatment temperature upon casting of the melt which is overheated for this purpose.

Method for producing a stratified composite material

The invention describes a friction bearing with a steel support shell and a lead-free bearing metal layer on the basis of copper with the main alloy elements of tin and zinc, which layer is applied to the support shell. In order to combine advantageous sliding properties with favorable mechanical resilience it is proposed that the bearing metal layer has a share of tin of 2.5 to 11% by weight and a share of zinc of 0.5 to 5% by weight, with the sum total of the shares of tin and zinc being between 3 and 13% by weight.

Friction bearing

A method is described for producing a stratified composite material, with a layer of sinterable solids particles being applied to a strip-like metal carrier and being sintered with liquid phase by the supply of heat continuously in the forward feed direction. In order to provide simplified production conditions it is proposed that the metal carrier is heated continuously in the forward feed direction with a temperature profile which decreases towards lower temperatures from a maximum temperature above the melting temperature of the solids particles in the region of a surface layer receiving the particle layer towards a core layer of the metal carrier, and that the particle layer is sintered at least in a layer resting on the metal carrier by a heat transmission from the heated metal carrier.
