Abstract

The analysis of test results on stability to gas-abrasive erosion for systems of paint coatings based on the erosion-resistant disperse-reinforced enamel EP-5236 applied on aluminum alloy D16-T and fibreglass VPS-20 at impact angles α = 90° and 15° was carried out. Firmness of coatings was evaluated on changes of weight characteristics of samples. Resistance of paint coatings to gas-droplet erosion on samples from alloy D16-T and also from fibreglass VPS-20 was investigated. It is shown that using of erosion-resistant system of paint coatings based on disperse-reinforced enamel EP-5236 increases resistance to gas-abrasive and gasdroplet erosion
