Abstract: A self-lubricating bearing material is described, as well as a plain bearing of such a bearing material, the performance of which, under lubricant-free conditions, is so markedly improved that pv values of up to 6 MPa/m/s are achieved in an average load and speed range. The self-lubricating bearing material comprises a PTFE-containing polymer matrix with fillers comprising PbO and at least one metal fluoride. The PbO content is from 15-55 vol. % and the metal fluoride content is from 0.1-14 vol. %. Preferred metal fluorides are CaF.sub.2, PbF.sub.2 and MgF.sub.2. The addition of further fillers such as hard materials, pigments or fibrous material is possible. The proportion of further additives may amount to up to 40 vol. % of the PbO/metal fluoride fillers.

Abstract: Leakproof, adhesive, non-lamellar and pore-free antifriction coatings can be produced from essentially oxidation-sensitive dispersion alloys, with at least two metallic alloy components forming a miscibility gap in the solid state, by means of vacuum plasma-spraying with a practically homogeneous material distribution. Precipitation crystallites of alloy components are significantly below 5 .mu.m and fringe-crystal growth is definitely inhibited. By adding hard particles during the coating process further dispersion consolidation can be achieved. Such antifriction coatings improve longevity, corrosion resistance and emergency lubrication of sliding surfaces without reducing their running-in characteristics and their ability to bed in foreign matter. They can be deposited individually on to sliding bearing components or continuously on to supporting strips.

Abstract: A layered composite construction material, especially for sliding and friction elements, with a substrate, for example a steel layer, on which is a copper-containing or a tin-containing intermediate layer and then a tin-containing or copper-containing functional layer, together with an interposed diffusion barrier layer. Diffusion of tin between the functional and intermediate layers is minimized by forming the diffusion barrier layer by cathode sputtering of a metallic material which has essentially a cubic face-centered crystal lattice that is built up under a recrystallization process. Vacancy sites in the crystal lattice structure are avoided or removed, and a space filling of from 60% to the optimum 68% is achieved. Preferably the diffusion barrier layer is a nickel-tin alloy having a tin content of at least 10% by weight.

Abstract: A composite structural material particularly intended for frictional and slide elements, consisting of a substrate such as a steel layer with a copper- or tin-containing intermediate layer, a tin- or copper-containing functional layer and, between these last two layers, a diffusion barrier layer protecting against diffusion of tin from the functional layer into the intermediate layer or back to the diffusion barrier layer. The diffusion barrier layer consists of a metallic material having a hexagonal crystal lattice, which material is applied by cathodic sputtering, forming a material structure that is densely packed in vacuo with a space filling by metal ions of above 70%. For the cathodic sputtering, conditions of plasma pressure and substrate temperature can be chosen so that recrystallization occurs simultaneously with the formation of the diffusion barrier layer; this makes it possible to achieve the densest hexagonal packing, with a space filling of up to 74%.

Abstract: A composite bearing material for use in plain bearings, i.e., bearings without rolling elements, has a thermoplastic matrix which is reinforced by short fibers having a modulus of elasticity above 50 MPa and can contain friction-reducing particles as well as other fibers.

Abstract: A plain bearing comprising a support and a galvanically deposited bearing alloy deposited on said support in a thickness of about 0.01 to 0.1 mm from a bath containing metallic fluoroborates. The bearing alloy is a copper-free alloy of only tin, antimony and lead and consisting essentially of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead. The support comprises a steel support covered with lead or tin-bronze and a nickel containing barrier layer.

Abstract: The bearing is composed of a strong metallic backing, a softer metallic support layer, and a galvanically applied metallic anti-friction layer, the support layer and the anti-friction layer being of mutually different metals or metallic alloys. An intermediate layer is provided between the support layer and the anti-friction layer. The intermediate layer is made as a layer which prevents or limits diffusion of metallic components from the anti-friction layer into the supporting layer and vice versa, and is composed of a binding layer, entering into a lasting surface bond with the material of the anti-friction layer, and of an underlayer, entering into a lasting surface bond with the material of the support layer.

Abstract: A composite material for use as shock absorber, as bushings or the like having controlled friction characteristics of a layer bonded to a metal substrate is formed by applying a particulate composition of a thermoplastic synthetic resin and carbon fibers having a maximum length of 1 mm to the substrate and heating it to a temperature of 50.degree. to 70.degree. K. above the melting temperature of the synthetic resin.

Abstract: 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.

Abstract: A method for producing stratification mass for the production of top surfacing layers particularly through dipping, painting, filling or spraying on a carrier (especially for friction/slide layers of bearing laminates having metallic base members) of a matrix foundation substance of fluoride-held polymers which has admixed metal or metal-alloy particles and/or additive material with friction and/or slide-improving characteristics. The applied layer material is subjected to heat to melt the same, and the layer is then cooled and pressed. The synthetic substance of the matrix can contain a primer, such as chromium oxide.

Abstract: 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.

Abstract: A bearing laminate and method of producing the same, wherein a metallic suspension alloy having a tendency to dissociate is thermokinetically applied as a coating to a substrate, such coating in its solid state becoming dissociated. The substrate and the applied coating are mechanically compressed after the application and solidification of the latter. The surface of the substrate which receives the suspension alloy coating is especially prepared, either as a rough surfaced base or else as an aluminum or aluminum alloy surface having a surface activation and grain structure that is produced by a brief heating to a temperature between 450.degree. and the melting point of the aluminum or aluminum alloy, such heating destroying and removing the aluminum oxide.

Abstract: A slide bearing laminate and method for producing the same, wherein a low-friction composite facing or layer is secured to a carrier or foundation strip by a bonding procedure. The composite facing comprises textile material having a low-friction component on one side and a glueable component on the other side, which latter is bonded to the carrier strip. The adhesive or bonding agent preferably occupies the interstices of the composite facing, and is especially formulated to resist failure by being mixed not only with friction and heat-conducting filler elements but also with fibrous fillers which particularly contribute to the failure resistance.
