Abstract
A process for repairing a damaged annular region of an anode configured to emit x-rays includes the step of machining the damaged annular region made of an initial target coating to a depth smaller than a thickness of the coating so as to leave behind a residual annular layer. An intermediate layer is then deposited on the residual annular layer. A repairing layer is then deposited on the intermediate layer. A heat treatment is then performed using an anneal which causes, by interdiffusion and formation of a solid solution, the material of the intermediate layer and the material of the residual annular layer to diffuse into each other and further cause the material of the intermediate layer and the material of the repairing layer diffuse into each other. As a result of this anneal the intermediate layer disappears.
