Concave sliding element and production process therefor

Composite material for plain bearing elements of a type having a metallic backing and an overlay of aluminum-based bearing material applied on the back. The bearing material is a heterogeneous aluminum alloy having a matrix containing in addition to aluminum, nickel, manganese, and copper. There is dispersed within the matrix, segregated tin or segregated lead, in an amount of from 0.5% to 20% by weight in the case of tin. The matrix contains hard particles of nickel, manganese, nickel-manganese, and alloys of nickel-manganese, and are located in the bonding regions between the matrix and the segregated tin or segregated lead. The segregated tin or segregated lead deposits are substantially free of hard particles. The hard particles are substantially of a dimension .ltoreq.5 um. and are present in a quantity of less than 5 hard particles of a dimension .gtoreq.5 um. in a cube-shaped volume element, the edge of which is 0.1 mm. long.

In a laminate for friction bearing elements which contains, on a metallic support layer, an anti-friction layer comprising an aluminum alloy containing nickel, manganese and lead, there is additionally provided bismuth or copper which improve considerably the bearing properties and also facilitate the surface machining by chip removal of the anti-friction layer. It is of particular advantage if the aluminum alloy has the addition of both bismuth and copper, resulting in considerably improved sliding characteristics and improved emergency running properties in addition to substantially improved properties regarding strength, dynamic loadability, fatigue strength and good machinability.

Laminated anti-friction bearing material and process for producing the same. Heterogeneous wire, containing both metallic and non-metallic elements or components, is atomized by an electric current impulse discharge which causes an explosive or sputtering disintegration of the wire, resulting in the materials thereof being sprayed or deposited onto a substrate. The deposited coating can include a matrix formation in its make-up, with discrete anti-friction and other particles, and is characterized by a strong cohesion to the substrate, together with highly desirable sliding properties. The sputtering is accompanied by a controlled oxiding, or a controlled sulfidizing of the sputtered materials, and the sputtering can produce an improved anti-friction layer, and also an improved running-in layer.

Manufacturing method and high-stress resistant product produced thereby. The method involves electro deposition by cathodic electrolysis of a thin metallic layer of the oxide of the metal molybdenum, on the surface of a metal workpiece. The workpiece, which could be solid or else a laminate such as a slide bearing, thus has an adaptation surface capable of withstanding extremely high surface pressures and/or high temperatures, and of preventing metallic-surface abrasion or galling, and dry friction.
