Evaluation of adhesion strength of protective coatings with Al powder by adhesion work of initial suspension towards metal surface

Abstract

The influence of energetic factors upon surface properties of suspensions on the basis of Na-CMC with aluminum powder, used to produce anticorrosion coatings, is revealed. It is shown that relative adhesion work, got by measuring the extent of suspensions surface strain and the angles of wetting the steel surface with suspensions, correlate with adhesion strength of coatings containing aluminum powder.
