A method for investigating the defectiveness of composites of polymer anticorrosive coatings in highly aggressive environments

A quantitative assessment of both the initial heterogeneity of the structure of epoxy composites and the analysis of its development under the influence of aggressive media by local X-ray spectral analysis of the distribution of particles of inorganic fillers has been carried out. Statistical processing of X-ray spectral analysis profiles makes it possible to accelerate the assessment of changes in the size of the ID and the proportion of Z of various elements of the structure of the inorganic filler framework under the influence of physically and chemically active aggressive media. When filling a system based on an adaptive epoxy-phenol-formaldehyde-furan FF matrix with chromium oxide Cr2O3, a complex effect of reducing the proportion of P and the size of ID is observed.
