Determination of effect of metal surface preparation on resistance of epoxy-sand coating to aggressive media

Abstract

The composition and features of the manufacture of specimens of epoxy-sand composite used during the field repair of road construction machines are considered. The results of determining the influence of the preparation quality of a metal surface on resistance of the epoxy-sand coating to aggressive media are presented. It is shown that the quality of the filler preparation does not affect the coating resistance to aggressive media. It was found out that specimens with a pre-treated surface before applying the epoxy-sand composite coating showed the best resistance to aggressive media.
