Production method with thermal projection of a target

The invention relates to a method for producing a target by means of thermal projection, especially by plasma projection, said target comprising at least one compound selected from refractive metals, resistive oxides, and volatile oxides. The method is characterised in that at least a fraction of sa...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing a target by means of thermal projection, especially by plasma projection, said target comprising at least one compound selected from refractive metals, resistive oxides, and volatile oxides. The method is characterised in that at least a fraction of said compound in the form of a powder composition of the compound is projected by thermal projection onto at least part of the surface of the target, under a controlled atmosphere, and powerful cryogenic cooling jets directed towards the target during its construction are used.
