Abstract

The requirements to be met by a converter of the corrosion products (CCPs) of aluminum alloys are formulated, and the technique for expert assessment of its efficiency is developed. Accelerated, field, and strength tests of specimens with the exfoliation corrosion (EC) products incompletely removed were carried out. The effect of both the penetrability of a CCP composition and the surface treatment on the completeness of the EC products transformation and the paint coatings (PCs) adhesion were investigated. The CCP compositions with enhanced physicochemical properties and protective capacity, including those resistant to microbial corrosion, compatible with PCs and exerting no detrimental effect on their adhesion, are revealed.
