L'invention est basée sur l'utilisation d'une buse de texturation correspondant à WO97/30200, avec un nombre de Mach aussi élevé que possible, supérieur à 2. En outre, il est prévu un traitement thermique avant et/ou après texturation. La pression de l'air de traitement est portée à des valeurs de l'ordre de 10 à 14 bar ou plus.
