Abstract
A component made of superalloy is provided with a localized coating formed from three layers by a brazing heat treatment, the layers comprising an outer layer having a composition adapted to the specific surface properties sought, an inner layer having a composition which includes flux elements, and an intermediate layer obtained by the deposition of a mixture of the materials used for the other two layers.
