Abstract
Abstract A 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.
