The invention relates to a method for surface treating the surface (11') of a metal. The surface treatment is performed in a surfacing chamber (33), using a surfacing material (10), which is formed of one or more compounds and possible additives, and in which: the surfacing material (10) is brought to a principally gaseous state; the surfacing material (10) is led to the chamber (33); and the surfacing amterial (10) is permitted to react with the metal surface (11') being treated. The metal surface (11') being treated is subjected in the chamber (33) to a passing flow of the surfacing material (10), and in which the said surfacing material (10) comprises compound arising in dry distillation of deciduous-wood. The invention also relates to the equipment and surfacing material used in the method.
L'invention concerne un procédé permettant de traiter la surface (11') d'un métal. Le traitement de surface s'effectue dans une chambre de revêtement (33) utilisant un matériau de revêtement (10) formé d'un ou de plusieurs composés et d'additifs éventuels. Ledit procédé consiste à amener le matériau de revêtement (10) à un état essentiellement gazeux, à déposer ledit matériau (10) dans la chambre (33), et à faire réagir ce matériau (10) avec la surface (11') du métal à traiter. Ladite surface (11') est soumise, dans la chambre (33), à un écoulement du matériau de revêtement (10), ce matériau (10) comprenant des composants produits par distillation sèche de feuillus. L'invention concerne également l'équipement et le matériau de revêtement utilisés dans ledit procédé.
