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

The invention describes a bearing element (), comprising a protective layer (), a bearing metal layer () applied over the protective layer () and a sliding layer () applied by sputtering over the bearing metal layer (). A sliding paint layer () is applied onto the sliding layer ().

Bearing element

The invention relates to an alloy consisting of at least three components A, B, C, which form at least a first matrix and a soft phase dispersed therein, with a first surface () and a second surface () lying opposite it, the proportions of components A, B, C in the alloy being different from one another in the regions of the first () and the second surface (). At least one of the components forms a hard phase and at least one of the other components forms another matrix different from the first matrix, the first matrix being disposed at least in the region of the first surface () and the other matrix being disposed at least in the region of the second surface (), whilst the hard phase is dispersed through both the first and the other matrix.

Layered material

A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.
