STRATIFORM WORK MATERIAL WITH FUNCTION LAYER EXECUTED ON SUBSTRATE AND ITS MANUFACTURE

摘要

The functional layer is composed of at least two different substances e.g. aluminium and lead and is applied by plasma spraying of a mixture of the substances, which can be either a mixture of powdered substances or a composite material, e.g. in the form of a wire, containing the substances. The functional layer is supplied in a chronological sequence of several plasma spraying steps with different compositions of the mixture onto a backing layer e.g. steel strip and is used in bearing applications.
