Abstract

Procédé de détermination d’un défaut dans un revêtement recouvrant une pièce d’un aéronef et pièce d’aéronef recouverte de couches de revêtement L’invention concerne un procédé de détermination d’un défaut (140) dans un revêtement recouvrant une pièce (100) d’un aéronef, dans lequel ladite pièce est recouverte d’au moins une première couche de revêtement (120) comportant au moins un pigment luminescent produisant, sous une lumière d’un spectre visible, une première couleur et, sous une lumière d’un spectre ultraviolet, une seconde couleur, distincte de la première couleur, ledit procédé comportant : une opération d’éclairage de la pièce d’aéronef (100), au moyen d’une lampe (200) émettant une lumière de spectre ultraviolet, etune opération d’observation de ladite pièce d’aéronef (100) pour détecter si une portion de ladite pièce présente une couleur différente de l’ensemble de la pièce, correspondant à un défaut de revêtement, la première couche de revêtement étant de la même couleur qu’un matériau dans laquelle la pièce est fabriquée de sorte que, sous un éclairage de spectre visible, la couche de revêtement et la pièce apparaissent de la même couleur, un défaut de revêtement n’étant alors pas visible, et que, sous un éclairage de spectre ultra-violet, la couche de revêtement et la pièce apparaissent de couleurs différentes, un défaut de revêtement étant alors décelable. Figure à publier avec l’abrégé : Figure 2Method for determining a defect in a coating covering a part of an aircraft and aircraft part covered with layers of coating The invention relates to a method for determining a defect (140) in a coating covering a part (100 ) of an aircraft, in which said part is covered with at least a first coating layer (120) comprising at least one luminescent pigment producing, under light of a visible spectrum, a first color and, under light of a visible spectrum 'an ultraviolet spectrum, a second color, distinct from the first color, said method comprising: an operation of lighting the aircraft part (100), by means of a lamp (200) emitting ultraviolet spectrum light, andan operation of observing said aircraft part (100) to detect if a portion of said part has a different color from the whole of the part, corresponding to a coating defect, the first coating layer being of the same color as a material in which the part is manufactured so that, under visible spectrum lighting, the coating layer and the part appear the same color, a coating defect then not being visible, and that, under Ultra-violet spectrum lighting, the coating layer and the part appear different colors, a coating defect then being detectable.
