Method for manufacturing massive components made of intermetallic materials

摘要

The invention relates to a method for manufacturing a massive component substantially wholly made of intermetallic material, comprising the steps of:
a) preparing a mixture of powders of at least two metallic elements, the powders being present in the mixture in a proportion by weight corresponding to the atomic percentage in which the at least two metallic elements are present in a corresponding intermetallic compound which may be formed from these metallic elements;
b) applying a plurality of layers of such a mixture of powders by cold spraying on a substrate (S) so as to obtain, on the substrate (S), a preform of metallic mixture of predetermined thickness;
c) thermally treating at least the preform of metallic mixture so as to cause the reaction between the at least two metallic elements to form the corresponding intermetallic compound; and
d) removing the substrate (S), thus obtaining the massive component made of intermetallic material.
