Title
(EN) CERAMIC COATING
(FR) REVETEMENT CERAMIQUE
Abstract
(EN)
The invention relates to non-porous, non-permeable protective ceramic layers of a thickness of less than 50 μm, preferably of a thickness of less than 5 μm and still more preferably of a thickness of less than 1 μm, which have been bonded to a substrate through an intermediary layer which contains ions of the surface to be covered, while in the case of substrates consisting of metals or alloys, the oxide of the covered material is not demonstrable with x-ray diffraction.
(FR)
L'invention concerne des couches céramiques de protection imperméables non poreuses, qui présentent une épaisseur inférieure à 50 μm, de préférence une épaisseur inférieure à 5 μm ou, mieux encore, une épaisseur inférieure à 1 μm. Ces couches sont fixées à un substrat par une couche intermédiaire contenant des ions de la surface à revêtir. Dans le cas de substrats constitués de métaux ou d'alliages, l'oxyde du matériau revêtu n'est pas déterminable par cristallographie par rayons X.
