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.
