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.
