Abstract
Le procédé est destiné à la fabrication d'une électrode comprenant un noyau en un métal ayant une bonne conductibilité thermique et une gaine extérieure en un matériau résistant à la corrosion. Ce procédé comprend la superposition de deux flans 10, 11, respectivement d'un premier et d'un second métal ayant les caractéristiques précitées, les faces des deux flans etant en contact direct à leur interface 13; le chauffage de la zone du flan 10 du premier métal adjacente à l'interface 13 principalement par conduction de chaleur à partir du flan 11, jusquà ce que ladite zone entre en fusion, le refroidissement des flans 10, 11 de façon à les souder ensemble, et l'extrusion des deux flans assemblés de façon à produire une électrode formée d'un noyau du premier métal compris à l'intérieur d'une gaine du second métal. Application aux bougies d'allumage.
