摘要:
Method of online characterization of a layer of oxides on a steel substrate Method of characterization of a layer of oxides (22) present on a steel substrate (21), comprising the steps of: - providing a portion of the steel substrate comprising a layer of oxides wherein the portion defines an oxide surface, - collecting light (Lr) from said oxide surface using a hyperspectral camera (20) in order to obtain intensity values (I λ,M ) respectively representative of an intensity of a part (Lr λ,M ) of the collected light, wherein each part is respectively collected from one of a plurality of points (M) located on said oxide surface and respectively has a wavelength (λ) from a plurality of wavelengths, - comparing the obtained intensity values with reference intensity values obtained for reference oxides, and - calculating amounts of reference oxides in the layer.
