Abstract: A structure including at least one electrical line on one surface of the structure, one electrically conductive layer of the line resulting from deposition of an electrically conductive material via a cold spraying method, and the line includes a protective bonding layer on which the electrically conductive material is deposited via the cold spraying method, the protective bonding layer forming a continuous protective shield between the structure and the cold-sprayed material. An insulating layer is advantageously located between the structure and the protective bonding layer. Achieving an electrical line on a surface of the structure involves implementing a step of oxy-fuel flame spraying of a protective material to form a protective bonding layer, followed by a step of cold spraying of the electrically conductive material of the electrically conductive layer onto the protective bonding layer.
