Abstract

The method involves providing a shell (10) in an alloy in a form that is close to a final form. The shell is arranged with a face (11) and another face (12) opposed to the former face. Powder of another alloy is deposited by cold projection at supersonic speed on the former face such that another shell (20) in another alloy is formed on the former shell. The latter shell is allowed to be interdependent of the former shell. A set of reliefs is allowed to act as anchoring points (19) of the latter shell with regard to the former shell.
