Abstract
Coatings prepared by the microarc oxidation (MAO) of aluminum alloys AMg-3 and V-95 with subsequent filling with poly-p-xylylene by vapor-phase polymerization on a surface are studied. It is found that filling with the polymer makes it possible to reduce the through porosity of MAO coatings by a factor of more than 5. It is shown that nuclear backscattering spectrometry with 7.5 MeV protons is an efficient and nondestructive method for measuring the composition and thickness of layered ceramic-polymer coatings.
