Title
(EN) METHOD FOR WELDING A TITANIUM COMPONENT WITH A TITANIUM NITRIDE COATING
(FR) PROCÉDÉ DE SOUDAGE D'UN COMPOSANT EN TITANE AYANT UN REVÊTEMENT EN NITRURE DE TITANE
Abstract
(EN) A workpiece (32) of Ti or a Ti alloy includes a surface with a coating layer of titanium nitride. A region of the surface includes a connection zone (34)of a Ti-N solid solution alloy. A second Ti or Ti alloy workpiece (42) is contacted with the connection zone, and a weld joint (55) is formed across the connection zone with a resistance welding process. The weld joint (55) extends into the first Ti workpiece (32) and the second Ti workpiece (42).
(FR) Une pièce à travailler (32) en Ti ou en un alliage de Ti comprend une surface ayant une couche de revêtement de nitrure de titane. Une région de la surface comprend une zone de connexion (34) d'un alliage de Ti-N en solution solide. Une seconde pièce à travailler (42) en Ti ou en un alliage de Ti est mise en contact avec la zone de connexion, et un joint de soudure (55) est formé à travers la zone de connexion à l'aide d'un processus de soudage par résistance. Le joint de soudure (55) s'étend dans la première pièce à travailler (32) en Ti et la seconde pièce à travailler (42) en Ti.
