Abstract
(EN)
The present invention provides a stainless steel sheet carbon composite material which has excellent electrical conductivity and excellent corrosion resistance, while additionally exhibiting excellent adhesion between a base material and a carbon layer. A stainless steel sheet carbon composite material according to the present invention is obtained by superposing a carbon layer, which contains a carbonaceous material and a matrix resin that is composed of a thermoplastic resin or a thermosetting resin, on at least one surface of a sheet-like base material that is formed of a stainless steel. This stainless steel sheet carbon composite material is configured such that: the base material contains at least 0.001-0.2% by mass of carbon (C), 9.0% by mass or more but less than 16.0% by mass of chromium (Cr) and 0.005-1.0% by mass of copper (Cu); and in a specific measurement range of the surface layer of the base material, the Cu content is from 0.01-0.3% by mass and the C content is 2-15% by mass as determined by quantitative analysis of elements in the thickness direction of the surface layer of the base material by means of glow discharge optical emission spectrometry. The present invention also provides a stainless steel sheet which is used for this stainless steel sheet carbon composite material.

La présente invention concerne un matériau composite de carbone en feuille d'acier inoxydable qui présente une excellente conductivité électrique et une excellente résistance à la corrosion tout en présentant en outre une excellente adhérence entre un matériau de base et une couche de carbone. Le matériau composite de carbone en feuille d'acier inoxydable selon la présente invention est obtenu par la superposition d'une couche de carbone, qui contient un matériau carboné et une résine de matrice qui est composée d'une résine thermoplastique ou d'une résine thermodurcissable, sur au moins une surface d'un matériau de base en forme de feuille qui est formé d'un acier inoxydable. Ce matériau composite de carbone en feuille d'acier inoxydable est configuré de sorte que : le matériau de base contient au moins 0,001 à 0,2 % en masse de carbone (C), 9,0 % en masse ou plus mais moins de 16,0 % en masse de chrome (Cr) et 0,005 à 1,0 % en masse de cuivre (Cu) ; et dans une plage de mesure spécifique de la couche de surface du matériau de base, la teneur en Cu est de 0,01 à 0,3 % en masse et la teneur en C est de 2 à 15 % en masse telles que déterminées par une analyse quantitative d'éléments dans la direction de l'épaisseur de la couche de surface du matériau de base au moyen d'une spectrométrie d'émission optique à décharge luminescente. La présente invention concerne également une feuille d'acier inoxydable qui est utilisée pour ce matériau composite de carbone en feuille d'acier inoxydable.
